Effects of naturally-occurring acid fog on inflammatory mediators in airway and pulmonary functions in asthmatic patients. (1/58)

Floating fog occurs every summer in Kushiro City in Japan, and the annual average of fog water pH in the past 4 years has been under 5.0. We previously reported that epidemiologically fog was the most important positive factor contributing to increased hospital visits of asthmatic patients compared with other meteorological values and air pollutants. This study aimed to investigate the mechanism of the effects of naturally-occurring acid fog on asthmatic patients. We compared pulmonary functions and inflammatory mediators in induced sputum between the foggy (July 1995) and the non-foggy (May 1996) season, and assessed airway responsiveness to hypo-osmolar aerosol. Forty-four out of 118 asthmatic patients of Kushiro City residents participated, pulmonary function tests were completed in 36 patients, and sputum data were available in 26 patients in both seasons. Percent forced expiratory volume in 1 sec (FEV1) was significantly (P< 0.05) decreased, and % peak expiratory flow rate (PEFR) had a trend to decrease in the foggy season more than in the non-foggy, and sputum eosinophil cationic protein (ECP) and interleukin (IL)-8 were higher in the foggy season but not significantly. A moderate inverse correlation was revealed between sputum ECP and %PEFR in the foggy season (r= -0.55, P<0.005). Subjects were divided into two groups according to the best PEFR; one had >10% lower PEFR levels in the foggy season than in the non-foggy season (Group A, n = 7), the remainder did not (Group B, n = 19). In group A, sputum ECP was significantly increased (P< 0.01) in the foggy season, but there were no changes in IL-8 and prostaglandin D2. Ultrasonic nebulized distilled water provocation test revealed no differences between group A and B. These results suggested that eosinophilic inflammation rather than hypo-osmolar effect of fog might contribute to respiratory deterioration by inhalation of naturally-occurring acid fog.  (+info)

Evaluation of ionic pollutants of acid fog and rain using a factor analysis and back trajectories. (2/58)

Fog and rain water samples were collected at the same time in the Akita Hachimantai mountain range in northern Japan from June to September in 1998 and 1999. The various ion concentrations in these samples were analyzed, and the fog droplet sizes were measured for each fog event. As the fog droplet size increased, the ion concentration decreased. The slope of log-log plots of the concentration versus the droplet size differed with the kind of ion. In order to characterize the air pollutant, moreover, these data were quantitatively analyzed by an oblique rotational factor analysis. We found that three factors were extracted as the air pollutant source: (NH4)2SO4, acids (HNO3 + H2SO4) and sea-salt. Combining the factor analysis with the 72 h back-trajectory at 850 hPa level, we found that the contribution of each factor varied with the transport pattern of air masses.  (+info)

Adverse effects of acid rain on the distribution of the Wood Thrush Hylocichla mustelina in North America. (3/58)

Research into population declines of North American bird species has mainly focused on the fragmentation of habitat on the breeding or wintering grounds [Robinson, S. K., Thompson, F. R., Donovan, T. M., Whitehead, D. R. & Faaborg, J. (1995) Science 267, 1987-1990]. In contrast, research into declines of European species has mainly focused on intensification of agriculture [Donald, P. F., Green, R. E. & Heath, M. F. (2001) Proc. R. Soc. London Ser. B 268, 25-29] and the role played by the atmospheric deposition of pollutants, in particular, acid rain [Graveland, J. (1998) Environ. Rev. 6, 41-54]. However, despite widespread unexplained declines of bird populations in regions of heavy wet acid ion deposition [Sauer, J. R., Hines, J. E. & Fallon, J. (2001) The North American Breeding Bird Survey Results and Analysis 1966-2000 (Patuxent Wildlife Research Center, Laurel, MD)], no North American studies have presented evidence linking such widespread terrestrial bird declines to acid rain. To address the question of the role played by acid rain in population declines of eastern North American songbird species, we combine data from several sources. We use a multiple logistic regression model to test for adverse effects of acid rain on the Wood Thrush, while controlling for regional abundance, landscape-level habitat fragmentation, elevation, soil pH, and vegetation. We show a strong, highly significant, negative effect of acid rain on the predicted probability of breeding by this species, and interactions with elevation, low pH soils, and habitat fragmentation that worsen these negative effects. Our results suggest an important role for acid rain in recent declines of some birds breeding in the eastern United States, particularly in high elevation zones with low pH soils, and show the need to consider other large-scale influences, in addition to habitat fragmentation, when addressing bird population declines.  (+info)

Whither acid rain? (4/58)

Acid rain, the environmental cause celebre of the 1980s seems to have vanished from popular conscience. By contrast, scientific research, despite funding difficulties, has continued to produce hundreds of research papers each year. Studies of acid rain taught much about precipitation chemistry, the behaviour of snow packs, long-range transport of pollutants and new issues in the biology of fish and forested ecosystems. There is now evidence of a shift away from research in precipitation and sulfur chemistry, but an impressive theoretical base remains as a legacy.  (+info)

Nitrogen deposition in the greater Tehran metropolitan area. (5/58)

An investigation of air pollution in the Tehran metropolitan area between 1992-2000 indicated that there are significant amounts of nitrate ion (NO3-), over 30 kg/ha/year, deposited as wet deposition, compared to 13 kg/ha/year in the Chitgar Parkland near the Tehran metropolitan area. The amount of NO3- in warm seasons is twofold that of cold seasons, and there was a significant difference between cold and warm seasons. Annual wet deposition of ammonia (NH3) was 10 kg/ha/year in the Chitgar Parkland.  (+info)

To trade or not to trade? Criteria for applying cap and trade. (6/58)

The use of emissions trading (cap and trade) is gaining worldwide recognition as an extremely effective policy tool. The U.S. Sulfur Dioxide (SO2) Emissions Trading Program has achieved an unprecedented level of environmental protection in a cost-effective manner. The successful results of the program have led domestic and foreign governments to consider the application of cap and trade to address other air quality issues. Certain analyses are particularly important in determining whether or not cap and trade is an appropriate policy tool. This paper offers a set of questions that can be used as criteria for determining whether or not cap and trade is the preferred policy approach to an environmental problem.  (+info)

Anthropogenic effects on forest ecosystems at various spatio-temporal scales. (7/58)

The focus in this review of long-term effects on forest ecosystems is on human impact. As a classification of this differentiated and complex matter, three domains of long-term effects with different scales in space and time are distinguished: Exploitation and conversion history of forests in areas of extended human settlement, Long-range air pollution and acid deposition in industrialized regions, Current global loss of forests and soil degradation. There is an evident link between the first and the third point in the list. Cultivation of primary forestland--with its tremendous effects on land cover--took place in Europe many centuries ago and continued for centuries. Deforestation today is a phenomenon predominantly observed in the developing countries, yet it threatens biotic and soil resources on a global scale. Acidification of forest soils caused by long-range air pollution from anthropogenic emission sources is a regional to continental problem in industrialized parts of the world. As a result of emission reduction legislation, atmospheric acid deposition is currently on the retreat in the richer industrialized regions (e.g., Europe, U.S., Japan); however, because many other regions of the world are at present rapidly developing their polluting industries (e.g., China and India), "acid rain" will most probably remain a serious ecological problem on regional scales. It is believed to have caused considerable destabilization of forest ecosystems, adding to the strong structural and biogeochemical impacts resulting from exploitation history. Deforestation and soil degradation cause the most pressing ecological problems for the time being, at least on the global scale. In many of those regions where loss of forests and soils is now high, it may be extremely difficult or impossible to restore forest ecosystems and soil productivity. Moreover, the driving forces, which are predominantly of a demographic and socioeconomic nature, do not yet seem to be lessening in strength. It can only be hoped that a wise policy of international cooperation and shared aims can cope with this problem in the future.  (+info)

An approach to balancing the positive and negative effects of elevated nitrogen oxides in the lower atmosphere on terrestrial plants. (8/58)

Elevated NOx in the lower atmosphere has three major effects on terrestrial plants. On the one hand, it causes an increase in surface ozone concentration. This reduces plant growth rate. On the other hand, elevated NOx causes an increase in the flux of oxidized N compounds from the atmosphere to the land surface. This plays a dual role in the life of terrestrial plants. Additional N in soils stimulates plant growth (N-fertilization effect), whereas soil acidification may negatively affect plants. A simple empirical model for calculating the overall effect of anthropogenic increase in NOx level has been developed. The model is based on experimental "cause-response" data presented in world scientific literature. Calculations showed that at the large scale, among the above-mentioned changes, elevated O3 plays a major and negative role in plant life. Its negative effect on plants is partly compensated by N fertilization in unmanaged ecosystems. Such compensation appears to be negligible in agricultural lands. There are vast territories in Euro--Asia--for instance, a territory of Russia--in which acid atmospheric deposition has no significant effect on terrestrial plants.  (+info)

There was a more effect of acid rain water in 0% and 8% as is basic Acid rain may cause the increase in breathing problems of adults and children. The United States and Canada begin study of cross-border acid rain transport. The term acid rain is actually somewhat misleading because even pure rainwater collected in areas remote from civilization is slightly acidic (pH ≈ 5.6) due to dissolved carbon dioxide, which reacts with water to give carbonic acid, a weak acid:. Generally rain water gets acidic because CO 2, SO 2 and NO 2 present in the atmosphere get dissolved in it forming carbonic acid (H 2 CO 3), sulphuric acid (H 2 SO 4) and nitric acid (HNO 3) respectively. Dec 17, 2018 · Rain that has a higher hydrogen ion concentration than about 10-5 M is referred as acid rain. Essay on Acid Rain. Pollution, volcanic eruptions, power-generating plants, forest fires and even lightning bolts are some of the causes of acid rain.

Introduction. ACID RAIN An international concern Gursharn Sandhu 10CR Acid rain: I am for, the reduction of sulphur dioxide and nitrogen oxide, emissions, by 90% by the year 2010. We need to take drastic action because the effects on us are all very serious. We must protect ourselves and safeguard our future. Acid rain is the term used to describe one of the worst effects of nature. Acid rain is a mixture of sulphur dioxide, and nitrogen oxides, which are gasses being emitted into our atmosphere. These gases combine with water droplets in the atmosphere, to produce acid rain. These toxic gasses enter the clouds, so rain is highly acidic. As a result of acid rain, we suffer from terrible air pollution, so the government should recognize, this problem, and do something about it. Acid rain has a pH of about 2. This makes it very harmful, and dangerous. Acid rain is produced in countries with areas that are surrounded by industrialised buildings, such as coal fire power stations, working ...

There are many problems and effects caused by acid rain. Acid rain can cause buildings, statues and bridges to deteriorate faster than usual. another problem is it harms thousands of lakes, rivers, and streams worldwide. It disrupts lake ecosystems and kill wildlife in affected lakes, rivers and streams. Acid rain also damages soil and the tree roots in it. When soil is acidified, tree roots are damaged, leaving them not able to draw in enough nutrients to support the tree. When acid rain falls on trees, it makes their leaves turn brownish-yellow and the tree can no longer carry out photosynthesis properly. Another problem is it will harm people when they breathe in smog, acid rain in one of its many forms. Acid rain can also harm people in-directly. This happens when people eat fish caught in affected lakes or rivers. Also, if the water source is acidic enough, it will react with copper or lead pipes to harm humans. It also washes aluminum into the water supply. Birds can be harmed if they live ...
Acid rain is rain that contains nitric and sulfuric acid. Snow and fog can also contain nitric and sulfuric acid, and the dangerous effects are the same whether the acid is falling to the earth by rain or snow, or dancing in the air via fog. Any precipitation or dust particle that contains abnormal levels of sulfur dioxide and nitrogen oxides is considered acid rain. Acid rain primarily affects the United States, Europe, and China. Acid rain directly affects the chemical and pH balances in ground water. The excess aluminum created by acid rain makes aquatic environments such as the sea, lakes, and streams, toxic. The animals that can withstand the imbalance of the waters natural minerals might survive, but quickly lose their food source as the weaker creatures die off. Animals that cannot withstand the chemical imbalances die, fail to reproduce, become deformed due to bone decalcification, or fail to grow normally. Algae growth is increased by acid rain, and rock scaling microbial and ...
Acid rain is created when rain mixes with pollution in the air. Pollution fills the air with an invisible gas called sulfur dioxide. (This gas is mainly a result of coal burning.) Sulfur dioxide combines with water in the air and sunlight to form a weak sulfuric acid that gives acid rain its bitter taste.. Acid rain can fall hundreds of miles from the nearest factory smokestacks. In cities, acid rain can cause damage and decay of buildings and statues. In rivers and lakes, it can kill fish, and on land, it can damage soil needed for the proper growth of plants.. Acid rain is a type of acid deposition, which can appear in many forms. Wet deposition is rain, sleet, snow, or fog that has become more acidic than normal. Dry deposition is another form of acid deposition, and this is when gases and dust particles become acidic.. Both wet and dry deposition can be carried by the wind, sometimes for very long distances. Acid deposition in dry form can be inhaled by people and can cause health problems ...
Acid rain is caused mostly by the combustion of fossil fuels containing sulfur and nitrogen. When sulphur and nitrogen are combusted, sulphur dioxide and nitrogen oxides are created and released into the atmosphere. Once these gases come in contact with water they become acids (Sulphuric acid and Nitric acid). This can happen either through wet deposition when rain, sleet or snow remove the gases from the air or through dry deposition when particles are deposited and absorbed into surfaces and later converted into acids when they come into contact with water. Coal power plants, electricity generation, driving a car, volcanoes and thunderstorms all contribute to acid rain. While there are natural causes of acid rain as mentioned, 90% of harmful emissions are a result of man-made sources. Acidity of rainwater is measured by the pH scale. It ranges from 0 which is highly acidic to 14 which is highly alkaline (basic). The scale point 7 is neutral. Clean rain measures at pH 5.6 while acid rain is ...
Lakes and streams in North America and Europe are beginning to recover from the damage inflicted by acid rain, scientists report. The recovery is being attributed to the passage and enforcement of environmental regulations and international agreements that reduce the emissions that produce acid rain. Emissions from burning fossil fuels steadily increased from the beginning of the Industrial Revolution in the 18th century until the 1970s. The sulfur and nitrates released into the atmosphere eventually return to the Earth as acid rain. This study provides the first conclusive evidence that international and regional agreements designed to reduce the emissions that cause acid rain, beginning with the United Nations First Sulphur Protocol in 1985, are working. Sulfur dioxide concentrations in north/central Europe air decreased by 63 percent between 1985 and 1996, according to the report. Sulfur dioxide is converted in the atmosphere to sulfuric acid, the main ingredient that produces acid rain. The ...
Preventing acid rain is the only way to stop its deadly impact on the environment. Acid rain is caused by pollution. It is released into the air naturally during a volcanic eruption, but the primary cause of excess nitric and sulfuric acid in the environment is manmade. Conserving energy is the number one way humans can prevent acid rain. Using less energy at home decreases the need for power plants. People also need to get out of their car. Using public transportation, biking or walking to destinations leaves fewer cars on the road, less emissions in the air, and a decreased dependency upon fossil fuels. Finally, manufacturing plants can reduce the emissions that cause acid rain by using scrubbers to clean and remove the dangerous chemicals from the pipes before they are released into the air ...
Many severe effects of air pollution on materials and structures come from acid rain. Acid rain dissolves limestone, marble, cement and sandstone. Acid rain stains and etches granite and corrodes metals like bronze. Acid rain damages structures such as the Taj Mahal and Thomas Jefferson Memorial.
Acid rain was a very common phenomenon before many governments stepped in to put an end to it. It is a term given to precipitation which contains various acids, but mostly sulfuric acid, which get formed when gases emitted by industry and vehicles combine with water droplets in the air. Acid rain is the most common term for this precipitation although it can also take the form of snow or fog depending on the climactic conditions of the place where it occurs. Acid rain or snow has a devastating effect on the land where it falls. It can destroy vegetation as well as animal life. Trees are stripped bare of their leaves when this rain falls on them. It can also damage the soil for good, making it unfit for cultivation. The negative results of acid rain do not stop at this. The acids wash into rivers and lakes where they kill fish and other marine life mercilessly. Certain places at high altitudes have suffered greatly as a result of these acids especially when trees in these places are surrounded by ...
Since the Industrial Revolution, emissions of sulfur dioxide and nitrogen oxides to the atmosphere have increased. In 1852, Robert Angus Smith was the first to show the relationship between acid rain and atmospheric pollution in Manchester, England. Though acidic rain was discovered in 1852, it was not until the late 1960s that scientists began widely observing and studying the phenomenon. The term acid rain was generated in 1972. Canadian Harold Harvey was among the first to research a dead lake. Public awareness of acid rain in the U.S increased in the 1970s after the New York Times promulgated reports from the Hubbard Brook Experimental Forest in New Hampshire of the myriad deleterious environmental effects demonstrated to result from it ...
Although acid rain is made more acidic from the chemicals and pollution produced by human activity, some naturally occurring rain actually has acid content in it, up to a pH level of 5. However, alkaline materials in the air counteracts the acidity in naturally occurring acid rain.. Therefore, even if greenhouse gases are eliminated, there would still be naturally occurring acid rain, but not as damaging as acid rain caused by chemicals and pollution.. ...
acid rain Acid rain is perhaps the most well known and recognizable form of pollution that is affecting the world today. Acidity is measured using a pH scale, with 7 being neutral. So anything below 7 is considered to be acidic, but as far as acid rain goes, the baseline for identifying acid rain is generally below the pH level of 5.6. But there have been many debates over this value and many ...read more ...

Sulfur Dioxide (SO2) along with nitrous oxides, are two leading causes of acid rain. When SO2 is emitted into the atmosphere, it reacts with other chemicals to form sulfuric acid, which then returns to the surface through precipitation. Sulfur dioxide affects the lungs and makes it hard to breath. Sulfur dioxide reacts to form sulfate particles which when inhaled frequently enough can cause asthma or bronchitis. In operations with SO2 Gas Cylinders, where Sulfur Dioxide gas may accidently be released in large concentrations, it can cause immediate danger to life and health. In these applications, Heil provides emergency release scrubbers to reduce the risk of excessive exposure and contain the release. ...
Burning fossil fuels can cause acid rain, global warming, oil spills, and air and water pollution. All of these things are VERY bad for the environment. It affects the air we breathe, water we drink, and damages the ecosystem. Damaging the ecosystem will affect the lives we live for many years to come. In the US we use about 17 million barrels of oil every day. If you think that is bad 86% of US energy comes from fossil fuels. What Can You Do About It? What are Fossil Fuels? by Trisha Minocha Fossil Fuels are nonrenewable forms of energy from a million years ago. They come from underground and will not last forever. Coal, natural gas, and oil are fossil fuels ...

Reducing air pollution from the largest sources of emissions, including coal-fired power plants, is one of EPAs National Enforcement Initiatives for 2011-2013. SO2 and NOx, two key pollutants emitted from power plants, have numerous adverse effects on human health and are significant contributors to acid rain, smog, and haze. These pollutants are converted in the air to fine particles of particulate matter that can cause severe respiratory and cardiovascular impacts, and premature death. Reducing these harmful air pollutants will benefit the communities located near NIPSCO facilities, particularly communities disproportionately impacted by environmental risks and vulnerable populations, including children. Considering that air pollution from power plants can drift significant distances downwind, this settlement will reduce air pollution outside the immediate region ...
StateImpact Pennsylvania. By Susan Phillips. August 17, 2016. Air pollutants from Pennsylvanias natural gas production sites increased from 2013 to 2014, according to data released Wednesday by the Department of Environmental Protection. The air inventory data for shale gas production relies on information submitted by the industry, and includes emissions from compressor stations that utilize gas from coal beds, conventional, and unconventional wells. Although the number of well sites reporting information to the DEP dropped by 2.7 percent from 2013 to 2014, the number of pipeline related infrastructure sites increased by 12 percent.. Read enough? Click here to send a letter to Governor Wolf and your representatives.. Sulfur dioxide emissions saw the greatest jump, increasing 40 percent over 2013 levels. Sulfur dioxide contributes to acid rain, and causes respiratory problems including asthma. Other air pollutants that contribute to public health impacts also increased, including nitrogen ...
There is more nitrogen gas in the air than any other kind of gas. About 4/5ths of Earths atmosphere is nitrogen gas! A molecule of nitrogen gas is made up of two nitrogen atoms. There are other molecules in the atmosphere that have nitrogen atoms in them too, such as nitric oxide (NO) and nitrogen dioxide (NO2). These molecules are air pollutants. They are made in the engines of cars and other places. They also make other kinds of air pollution such as peroxyacetyl nitrate (PAN), a dangerous chemical in smog. They also help make nitric acid. Nitric acid is part of acid rain. Down on the land, nitrogen atoms are important parts of living creatures, soils, and even rivers. The Nitrogen Cycle explains how nitrogen atoms move around in the environment, including through living things like you and me! ...

Water is a natural solvent. Rain water is acidic due to carbon dioxide picked up in the atmosphere. Water and CO2 make carbonic acid (acid rain). Water hardness is primarily calcium and magnesium. Calcium is limestone - common throughout Midwest. Acid water dissolves limestone, iron, and other minerals in soil. All pure water has an affinity for metals. Surface water supplies are generally low in dissolved minerals. Well supplies vary in dissolved minerals with depth and location. pH is the measure of acidity of a water supply based on the hydrogen ion. Water with a pH below 7.0 is corrosive. Above is considered alkaline water which is not a problem except in industry.. Ionization. Minerals dissolved in water are present as ions. Ions have an electrical charge; either positive or negative. Ion exchange resins take advantage of this charge. Water Softeners are cation exchangers meaning they will exchange, or pick up all positive ions. Positive ions are calcium, magnesium, iron, copper, lead, ...
Making Peace With the Planet, by Barry Commoner. The assault on environmental quality results from the use of systems of production that yield useful goods but also generate pollutants.. The engines that power modern cars and trucks also produce pollutants that turn into smog and acid rain. Once disseminated, the synthetic pesticides and chemical fertilizers heavily used in agricultural production also become toxic pollutants that poison our water and food. As the petrochemical industry produces plastics, detergents, and numerous other synthetic chemicals, it also generates almost as much in toxic emissions.. Fuel-burning and nuclear power plants produce electricity; but the one also emits gases that are overheating the planet, and the other leaves huge stores of radioactive waste that will outlive the industry itself.. The current environmental crisis is the unanticipated outcome of the ways in which the corporations that are entrusted with these decisions have chosen to provide us with ...
Advances in hydraulic fracturing, or fracking, to obtain natural gas have made this resource an abundantly available and comparatively inexpensive source of fuel. While electric utility generators have traditionally favored large coal-or nuclear-powered plants to supply electricity to a designated grid, natural gas has steadily risen in popularity within this sector since the 1990s - if it continues along its current path, natural gas is projected to overtake coal and nuclear power as a primary source of alternative energy over the next few decades. Automakers, however, are still struggling to put Americas prodigious volumes of natural gas to their use. While coal may still be the cheapest means of generating electricity, it is also the dirtiest, causing smog, soot, acid rain, and other toxic air pollutants. Natural gas burns cleaner, and releases dramatically fewer emissions into the atmosphere - a nearly 30 percent reduction in carbon output and toxins. Its also cheaper by as much as $1 per ...

for you no longer have a harbor. Two boys casting a fishnet below gas flares, sulfuric dioxide, methane, acid rain. And despair, my body a fallen tree. So let 350 be the bridge I become lifting my child when our kayak doesnt meet the dock. Fighting to get back 350: hydroponic tomatoes, hoop-house lettuce, neighbors planting pawpaw trees. My man pushing a wheelbarrow, bending to gather storm-tossed sticks. 350 is more bike lanes, more skateboards. More darning of socks. My daughter about to be born: too late for a heparin lock, a heart monitor-only the power within me, the pain for which Ive longed, and her release into our world gone beyond its limit. Contract. Push. Put a door in the side of the ark and make lower, middle, and upper decks. 350, let it be a boomerang, a ricochet. A beeswax candle on my birthday cake. 350, your husband, daughter . . . and you will enter . . . sister, lover, lifelong partner snugged against the fine ark of your ribs. ...
The reason sulfur is important isnt that the world is running short. Quite the opposite: Theres enough locked away in the worlds fossil fuel deposits to feed current levels of demand for more than 7,000 years. The problem is that theres too much of it.. The proximate issue centers on the worlds shipping fleet. Atmospheric levels of sulfur dioxide have been falling since the early 1980s, when fears around acid rain, asthma and heart disease saw coal-fired power plants install scrubbers to remove the pollutant from their smokestacks. The maritime industry, however, has been stuck in the past.. For years, cargo ships have been powered by about 4 million barrels a day of the dirtiest, bottom-of-the-barrel fraction of crude, a tarry substance known as bunker fuel or residual fuel oil. Thats set to change in less than 18 months, after the International Maritime Organization adopted rules that would keep the sulfur content of the bunker fuel on standard ships below 0.5 percent from Jan. 1, ...

Much of the environment problems arise from the supply and utilization of energy for industrial, transportation and domestic markets. The use of fossil fuels can result in environmental, atmospheric, and terrestrial problems, including organic, acid rain, and global warming hazards. Here I will address the CO{sub 2} global greenhouse problem and touch upon the nuclear industry and its dilemma as well. We recognize the possibility of global natural feedback phenomena which may limit and mitigate anthropomorphic global greenhouse climate change, however, here I am limiting the discussion to anthropomorphic (man made) technological mitigation process as opposed to adaptation which means adapting to change. ...
As an international leader in refractories for SRUs, HarbisonWalker Internationals refractory products ensure that SRU reaction furnaces operate reliably when faced with high temperatures, increased throughput, and harsh, corrosive environments.. Di-Hydrogen-Sulfide and sour water are stripped from hydrocarbon products in other units of the refinery and routed through the SRU to be converted to elemental sulfur. Without this conversion, the sulfur oxides would be expelled into the air after incineration, resulting in acid rain and various health issues. The main focus of the SRU, the reaction furnace, burns part of the feed at temperatures up to 2800°F. The gases then pass through a series of converters and condensers that convert the acid gases to elemental sulfur and condense them to liquid. This method is known as the Claus process.. HarbisonWalker International offers a full portfolio of high-temperature alumina firebricks as well as lightweight brick and castables for efficient and ...
The process is already under way. During the Mao era, the Peoples Liberation Army ritualistically fired shells at the Taiwan-controlled island of Quemoy; now, the mainland spews garbage that floats across the mile-and-a-quarter-wide channel and washes up on Quemoys beaches at the rate of 800 metric tons a year. Acid rain caused by Chinas sulfur-dioxide emissions severely damages forests and watersheds in Korea and Japan and impairs air quality in the United States. Every major river system flowing out of China is threatened with one sort of cataclysm or another, including pollution (Amur), damming (Mekong, Salween), diverting (Brahmaputra), and melting of the glacial source (Mekong, Salween, Brahmaputra). The surge in untreated waste and agricultural runoff pouring into the Yellow and China Seas has caused frequent fish die-offs and red-tide outbreaks, and overfishing is endangering many ocean species. The growing Chinese taste for furs and exotic foods and pets is devastating neighboring ...
Introduction. In what way can the hydrological cycle be regarded as a system and what impact may human activity have on flows and stores? The hydrological cycle is a system, in the sense that it shows the global circulation of water/moisture between the atmosphere, land, and the seas and oceans. A system is a series of inputs outputs and outputs, and can be used at any scale. For example it could be either a global hydrological cycle or an individual drainage basin. In the global cycle there are a series of stores, such as the seas and the ice caps. It also contains flows or transfers that link the stores together. For example, evaporation. Water is moved between the stores, and the amount varies depending on the area or the given time. ...read more. Middle.

Unfortunately, it is difficult to reliably supply our bodies with sufficient magnesium, even from a good, balanced whole foods diet. First of all, modern agricultural methods favor the universal use of NPK fertilizers (nitrogen, phosphorus, and potassium). Both potassium and phosphorus are antagonists of magnesium in the soil, and on calcareous soils create a relative magnesium deficiency (the magnesium present is bound and therefore unavailable to the crop). On sandy or loamy soils that are slightly acid, an actual magnesium deficiency often exists, as the magnesium leaches from the soil and is also unavailable to the crop. This leaching also occurs in response to acid rain. Magnesium, in fact, is one of the most depleted minerals in farm soils. To add insult to injury, new plant hybrids are continually introduced that have been bred to survive on these mineral-depleted soils. Of course, when mineral-depleted crops are eaten by animals or by us, they will sooner or later cause disease. Even ...
Mapeshield CI 100 is a surface-applied corrosion inhibitor designed to penetrate concrete structures and protect embedded steel reinforcement. It forms a protective layer on the surface of the steel reinforcing bar to inhibit corrosion caused by carbonation, the presence of chlorides and other contaminants in the concrete (such as deposits from acid rain and industrial pollution), and helps to prevent additional cracking and spalling in the future. Mapeshield CI 100 can be applied by spray, brush or roller. By diffusing into the hardened pore structure of concrete to the steel reinforcing bars, Mapeshield CI 100 delays the corrosion process and reduces overall corrosion activity. ARCAT provides architectural information on building materials, manufacturers, specifications, BIM families and CAD details.

Immediately following Iraqs invasion of Kuwait, predictions were made of an environmental disaster stemming from Iraqi threats to blow up captured Kuwaiti oil wells. Speculation ranging from a nuclear winter type scenario, to heavy acid rain and even short term immediate global warming were presented at the World Climate Conference in Geneva that November.[32][33] On January 10, 1991, a paper appearing in the Journal Nature, stated Paul Crutzens calculations that the setting alight of the Kuwait oil wells would produce a nuclear winter, with a cloud of smoke covering half of the Northern Hemisphere after 100 days had passed and beneath the cloud, temperatures would be reduced by 5-10 Celsius.[34] This was followed by articles printed in the Wilmington Morning Star and the Baltimore Sun newspapers in mid to late January 1991, with the popular television scientist personality of the time, Carl Sagan, who was also the co-author of the first few nuclear winter papers along with Richard P. Turco, ...
In Aesops fable about the boy who cried Wolf!, the point of the tale is that eventually there was a wolf, but the boy was not believed because he had given too many false alarms. In my view, the Covid-19 coronavirus is indeed a wolf, or at least has the potential to be one. Many people, including President Trump, think we are over-reacting, because so many past scares have been exaggerated. I think thats wrong.. Coming from you, a friend said to me the other day, thats scary. I am known as an obsessive and serial debunker of false alarms. I have been at it for almost 40 years ever since I realised as a science journalist in the 1980s that acid rain was being wildly overblown as a threat to forests (I was right). This scepticism has served me well. I did not believe that mad cow disease would kill hundreds of thousands of people, as some experts were claiming in the mid 1990s. In the end just 177 died. Likewise, I refused to panic over bird flu, swine flu, SARS or ebola.. I set out to ...

The Emeryville Research Center of Shell Development Company in Emeryville, California was a major research facility of Shell Oil Company in the United States from 1928 until 1972, when Shell Development relocated to Houston, Texas. Shell Developments Emeryville facilities were located on about 27 acres (110,000 m2), included nearly 90 buildings at its peak, and when decommissioned in 1972, employed a staff of about 1500. Tricresyl phosphate (TCP) and other gasoline additives were developed at Emeryville. Tar sands extraction and other techniques to increase oil reserves were studied at bench scale and in pilot plants. Shell Development also pioneered de-sulfurization methods and standards for gasoline and motor oil, which were significant in reducing acid rain and other adverse environmental effects of auto exhaust gases. Shell Development scientist Thomas Schatzky also pioneered fingerprinting techniques to identify oil spills origins. Shell Development Emeryville scientists created the epoxy ...

The main use of calcium carbonate is in the construction industry, either as a building material or limestone aggregate for road building or as an ingredient of cement or as the starting material for the preparation of builders lime by burning in a kiln. However, because of weathering mainly caused by acid rain,[17] calcium carbonate (in limestone form) is no longer used for building purposes on its own, but only as a raw/primary substance for building materials.. Calcium carbonate is also used in the purification of iron from iron ore in a blast furnace. The carbonate is calcined in situ to give calcium oxide, which forms a slag with various impurities present, and separates from the purified iron.[18]. In the oil industry, calcium carbonate is added to drilling fluids as a formation-bridging and filtercake-sealing agent; it is also a weighting material which increases the density of drilling fluids to control the downhole pressure. Calcium carbonate is added to swimming pools, as a pH ...

A serious underprediction of ambient sulfate (SO4(2-) by two comprehensive, Eulerian models of acid deposition, the Regional Acid Deposition Model (RADM) and the Acid Deposition and Oxidant Model (ADOM), was found in the National Acid Precipitation Assessment Program phase of the Eulerian Model Evaluation Field Study (EMEFS) model evaluation. Two hypotheses were proposed to explain the cause of the underprediction in RADM: insufficient SO4(2-) production by nonprecipitating convective clouds and insufficient primary SO4(2-) emissions. Modifications of the RADM cloud and scavenging module to better simulate nonprecipitating cumulus clouds are described in detail. Three contrasting pairs of tests using data from the EMEFS were applied to these hypotheses: source vs. downwind regions; mid summer vs. late summer seasons, sunny-dry vs. cloudy-wet synoptic types. The SO4(2-) emissions hypothesis, tested by artificially boosting SO4(2-) emissions, fared better than expected but was rejected because of ...

Abstract. North African dust reaches the southeast United States every summer. Measurements taken in Miami, Florida indicate that more than one-half of the surface dust mass concentrations reside in particles with diameters less than 2.1 μm, while vertical profiles of micropulse lidar depolarization ratios show dust reaching above four km during pronounced events. These observations are compared to the representation of dust in the MERRA-2 aerosol reanalysis and closely-related GEOS-5 Forward Processing (FP) aerosol product, both of which assimilate satellite-derived aerosol optical depths using a similar protocol and inputs. These capture the day-to-day variability in aerosol optical depth well, in a comparison to an independent sun-photometer-derived aerosol optical depth dataset. Measured near-surface dust mass concentrations slightly exceed model values, with most of the modeled dust mass in diameters between 2-6 μm. Modeled-specified mass extinction efficiencies equate light extinction ...
