Sulfur dioxide is sometimes used as a preservative (E number: E220[2]) in alcoholic drinks,[3] or dried apricots and other dried fruits due to its antimicrobial properties. The preservative is used to maintain the appearance of the fruit rather than prevent rotting. This can give fruit a distinctive chemical taste. Sulfur dioxide is also a good reductant. In the presence of water, sulfur dioxide is able to decolorize substances that can be reduced by it; thus making it a useful reducing bleach for papers and delicate materials such as clothes. This bleaching effect normally does not last very long. Oxygen in the atmosphere reoxidizes the reduced dyes, restoring the color. Sulfur dioxide is also used to make sulfuric acid, being converted to sulfur trioxide, and then to oleum, which is made into sulfuric acid. Sulfur dioxide for this purpose is made when sulfur combines with oxygen. This is called the contact process. According to Claude Ribbe in The Crime of Napoleon, sulfur dioxide gas was used ...

Sulfur dioxide is toxic in large amounts. It or its conjugate base bisulfite is produced biologically as an intermediate in both sulfate-reducing organisms and in sulfur-oxidizing bacteria, as well. The role of sulfur dioxide in mammalian biology is not yet well understood.[28] Sulfur dioxide blocks nerve signals from the pulmonary stretch receptors and abolishes the Hering-Breuer inflation reflex. It was shown that endogenous sulfur dioxide plays a role in diminishing an experimental lung damage caused by oleic acid. Endogenous sulfur dioxide lowered lipid peroxidation, free radical formation, oxidative stress and inflammation during an experimental lung damage. Conversely, a successful lung damage caused a significant lowering of endogenous sulfur dioxide production, and an increase in lipid peroxidation, free radical formation, oxidative stress and inflammation. Moreover, blockade of an enzyme that produces endogenous SO2 significantly increased the amount of lung tissue damage in the ...

It is a major air pollutant that is colorless and has a pungent smell, released from the combustion of fossil fuels such as coal and oil, in different industries, and it is also a product of the burning fuels in automobiles released from the vehicular exhausts. Natural sources of Sulphur dioxide include forest fires, plant decay and volcanic eruptions. Sulphur dioxide can enter our bodies in three ways: Ingestion, Inhalation and direct contact. As Sulphur dioxide is used as a food preservative, it can easily be ingested. High concentration of Sulphur dioxide on a long-term basis can result in breathing problems, respiratory illnesses such as Bronchitis, Emphysema and Pulmonary Edema, alterations in pulmonary defenses, and aggravation of existing cardio vascular diseases. Furthermore, there are also some precautionary measures that common man can take to ensure minimum interaction with Sulphur dioxide. These include the usage of Mass Transportation systems like Public Transport to make sure that ...

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. ...

The Obama Administrations proposal harms communities such as Muskogee, which is trying to create jobs and grow its economy. This rule is part of EPAs oncoming regulatory train wreck that will stifle growth and economic development in Muskogee, as well as in cities and towns across the nation. As Ranking Member of the EPW Committee, I have supported ...

Sulfur dioxide is a reducing bleach, and can counter the effects of oxidizing bleaches, thus preserving color in fruits dried in the sun. The combination of fruit acids and ultraviolet light would otherwise react with the colorful compounds in the fruit, making them pale. Sulfur dioxide is produced by burning sulfur in air (for preserving fruit), or by reacting sodium bisulfite in the water in a product such as wine. Sulfur dioxide kills yeasts, molds, and bacteria. ...

I was reading (in my HVAC/R text) that sulfur dioxide was used as a dual purpose refrigerant/lubricant in some machines in the 19th century, and was used on British warships up until the 1940s. I was wondering if there were any similar modern uses for sulfur dioxide? Also wondering if there are other modern refrigerants that are used as dual purpose?

In the summer months, the CFS conducted a targeted food surveillance project to assess the use of sulphur dioxide in fresh meat. Though commonly added to foods like dried fruits and fruit juices, sulphur dioxide is not permitted to be added to fresh, chilled or frozen meat. The project had been conducted after repeated detection of the use of the non-permitted chemical in fresh meat in recent years. Samples include pork, beef and mutton collected from various meat stalls. Of the 222 samples tested, the overall satisfactory rate was 95%, with 11 unsatisfactory results. Some involved repeat offenders. The unsatisfactory samples included nine fresh beef and two fresh pork samples with sulphur dioxide levels ranging from 20ppm and 390ppm. As sulphur dioxide is water soluble and of low toxicity, it does not pose serious health effects to the public. The CFS has taken follow-up action including issuing warning letters to the retailers concerned and taking further samples for testing. When there was ...

By Leah Burrows, SEAS Communications. For more than 15 years, the Chinese government has invested billions of dollars to clean up its deadly air pollution, focusing intensely on reducing emissions of sulfur dioxide from coal-burning power plants.. These efforts have succeeded in reducing sulfur dioxide emissions, but extreme pollution events are still a regular wintertime occurrence and experts estimate that more than 1 million people die per year in China from particulate air pollution.. New research from Harvard may explain why. It shows that a key to reducing extreme wintertime air pollution may be reducing formaldehyde emissions rather than sulfur dioxide.. The research is published in Geophysical Research Letters [2].. We show that policies aimed at reducing formaldehyde emissions may be much more effective at reducing extreme wintertime haze than policies aimed at reducing only sulfur dioxide, said Jonathan M. Moch, a graduate student at the Harvard John A. Paulson School of Engineering ...

The growth of aerosol due to the aqueous phase oxidation of sulfur dioxide by ozone was measured in laboratory-generated clouds created in the Cosmics Leaving OUtdoor Droplets (CLOUD) chamber at the European Organization for Nuclear Research (CERN). Experiments were performed at 10 and −10 °C, on acidic (sulfuric acid) and on partially to fully neutralised (ammonium sulfate) seed aerosol. Clouds were generated by performing an adiabatic expansion - pressurising the chamber to 220 hPa above atmospheric pressure, and then rapidly releasing the excess pressure, resulting in a cooling, condensation of water on the aerosol and a cloud lifetime of approximately 6 min. A model was developed to compare the observed aerosol growth with that predicted using oxidation rate constants previously measured in bulk solutions. The model captured the measured aerosol growth very well for experiments performed at 10 and −10 °C, indicating that, in contrast to some previous studies, the oxidation rates of SO2 in a

The Clean Air Transport Rule is a proposed rule of the EPA requiring significant reductions in sulfur dioxide (SO2) and nitrogen oxides (NOx) emissions that cross state lines. By 2014, the rule and other state and EPA actions would reduce power plant SO2 emissions by 71 percent over 2005 levels and NOx emissions by 52 percent, according to EPA estimates. The proposed rules will replace the EPAs 2005 Clean Air Interstate Rule, which was vacated in July 2008 by the D.C. Circuit Court. Acting under federal court order, the Obama administration proposed the new air-quality rules on July 6, 2010, for coal-burning power plants. The proposed rule would require NOx and SO2 emission reductions in 2012 and additional SO2 emission reductions in 2014.[24]. On August 21, 2012, a federal appeals court in Washington, D.C. ruled 2-1 against the Transport Rule. The court determined that the rule forced states to be accountable for pollution that was not theirs, potentially making some states responsible for ...

CHICAGO (February 19, 2020) --Today, the U.S. Environmental Protection Agency (EPA) and Illinois EPA announced their proposal to formally redesignate the Pekin area to attainment of the most recent federal air quality standard for sulfur dioxide. Recent air monitoring data show that air concentrations of sulfur dioxide in the area are now below the National Ambient Air Quality Standard (NAAQS) for sulfur dioxide, in addition to all other federal air quality standards set to protect public health. EPAs partnership with the State of Illinois has resulted in cleaner, healthier air in the Pekin area which is home to more than 40,000 people, said EPA Region 5 Administrator Kurt Thiede In addition to cleaner air, once Pekin is redesignated, local businesses will face fewer air permitting restrictions, paving the way for the infrastructure investment and economic development that help create jobs. Over the past two years, EPAs partnerships with states in Region 5 have dramatically improved air ...

Wednesday, April 9, 2008 Hawaii Volcanoes National Park remains closed today after high levels of sulfur dioxide vented from Kilauea. Continuing southeastern winds will exist through most of the day, causing much of the contamination to exist elsewhere on the Big Island. In addition to the park, the Volcano House hotel and Kilauea Military Camp remain evacuated. Volcano Charter School remains closed for a second day. Sulfur dioxide can cause irritation to the nose, eyes, throat, and respiratory tract. Residents in the area are recommended to avoid smoking, stay indoors, and drink plenty of fluids, among other suggestions. Residents living northeast of the volcano should be prepared to evacuate, mainly those living in Mauna Loa Estates, Ohia Estates, Volcano Village, the Keauhou Ranch area and the Volcano Golf Course region. Trade winds on Thursday may return the conditions to normal. However, people in the region should remain prepared to evacuate if necessary. ...

It has been claimed that the team has managed to nail down an alternative to sulphur dioxide in wine, which might be able to address the rising concerns on the same lines. The team has found two extracts contained within wine to replace sulphur dioxide, which is used to preserve wine, but it can cause serious reactions too including asthma attacks.. European researchers have made progress towards finding an alternative to adding sulphur dioxide to red wine and other foodstuffs, such as dried fruit, holding out the hope of making future festive seasons healthier for millions, said the European Commission, which has added some 3 million euros to the project.. It has apparently also found that those who drank the wine with the extracts could actually not figure out any major difference from the standard wine.. As of now, names of the extracts have been kept under covers. There are fair chances of unveiling new wines in May in order to see if consumers would be able to approve them or not.. ...

Ios atmosphere is very thin and composed mostly of sulfur dioxide, with some sulfur monoxide, sodium chloride, and atomic sulfur and oxygen. Ios volcanoes contribute most of the sulfur dioxide, but its atmospheric concentration is also maintained by sunlight-driven sublimation of frozen sulfur dioxide on the surface. Despite its many volcanoes around which the ground literally sizzles, the surface of Io is very cold, averaging around -150?C. The negligible atmosphere does nothing to trap in heat. The plumes from its many volcanoes probably freeze almost instantly and drift back down as sulfur dioxide snow. It is interesting and unusual for a volatile compound such as sulfur dioxide to pile up and blanket Ios entire surface when it would be expected to be lost in space or perhaps concentrated in Ios cold polar regions. On moons and on rocky planets with exospheres, volatiles such as light gases eventually escape into space. Even though much sulfur dioxide is spewed from Ios volcanoes and ...

Sulfur dioxide (SO2) is a pollutant gas produced by various human activities, including ore processing, petroleum refining, the operation of industrial boilers and the burning of oil and coal at power plants. Although natural processes like volcanic activity and biological decay are responsible for half of the worlds atmospheric sulfur, emissions caused by human activity far exceed natural emissions in the developed countries.. Sulfur dioxide is a respiratory irritant that can be harmful at high concentrations when breathed by people who are very young, very old or already suffering from health problems. It can also damage vegetation, corrode building materials and contribute to the production of airborne particulates and acid rain.. ...

This study examined short-term effects of urban air pollution in morning hours on schoolchildren and could therefore disregard fluctuations in ozone concentrations. Earlier studies in Linz 8, 10 have shown relatively low ambient ozone during school years and no possibility of examining elementary schoolchildren in the afternoon and during summer vacation when ozone was higher, but children less localisable. From morning tests of lung functions during the school year, no negative associations with ozone had been found (and some positive ones were spurious and caused by the inverse relationship between ozone and NO2). Mean daily oxygen concentrations ranged 0.3-30.5 µg·m−3 (median 4 µg·m−3). From earlier results at higher concentrations 8, the present sulphur dioxide exposure was considered to be negligible for changes in function of small airways.. The strong correlation between the three measures of particle mass and NO2 made it difficult to separate the impact of each exposure ...

The most sensitive point at which oxygen can be picked up at greatest risk to the wine is at the point of bottling. If this is not controlled all the good work to manage oxygen levels up to this point can be undone. At Encirc, our filler double-evacuates the bottles of any air, before charging them with nitrogen prior to filling. This means that the wine is then entering a near 100 per cent nitrogen environment and, as a result, oxygen pickup is minimal. Depending on the initial dissolved oxygen (DO) of the wine, we regularly bottle wine with 0.2ppm of dissolved oxygen, which is global best practice. Most companies would be nearer to 1.00ppm or even higher ...

Red muscadine grape (Vitis rotundifolia Michx.) wines are very susceptible to browning and overall loss of color quality during processing and storage. This study examined the effects of three pH levels (2.90, 3.20, 3.80), three sulfur dioxide levels (25, 50, 75 ppm free SO2), three storage temperatures (20°C, 30°C, 40°C), and three storage times (0, 3, 9 months). A higher pH resulted in a loss of color intensity and redness and increased browning during storage for nine months. Wine with lower pH had a greater loss of free, unpolymerized anthocyanins, which indicated greater polymerization in lower pH wine. Sulfur dioxide levels higher than 25 ppm free SO2 severely bleached the color of red muscadine wine and lessened browning in high pH wine only. High SO2 levels also lessened browning of wine stored at 20°C, but not at higher storage temperatures. Higher storage temperature greatly increased browning and anthocyanin loss during nine months of storage. Wine stored at 30°C or 40°C had ...

The short-term effects of nitrogen dioxide (NO2) on total, cardiovascular and respiratory mortality in 30 European cities participating in the Air Pollution on Health: a European Approach (APHEA)-2 project were investigated.. The association was examined using hierarchical models implemented in two stages. In the first stage, data from each city were analysed separately, whereas in the second stage, the city-specific air pollution estimates were regressed on city-specific covariates to obtain overall estimates and to explore sources of possible heterogeneity.. A significant association of NO2 with total, cardiovascular and respiratory mortality was found, with stronger effects on cause-specific mortality. There was evidence of confounding in respiratory mortality with black smoke and sulphur dioxide. The effect of NO2 on total and cardiovascular mortality was observed mainly in western and southern European cities, and was larger when smoking prevalence was lower and household gas consumption ...

Sulphur dioxide, or SO2, belongs to the family of sulphur oxide gases (SOx). These gases dissolve easily in water. Sulphur is prevalent in all raw materials, including crude oil, coal, and ore that contains common metals like aluminium, copper, zinc, lead, and iron. SOx gases are formed when fuel-containing sulphur, such as coal and oil, is burned, and when gasoline is extracted from oil, or metals are extracted from ore. SO2 dissolves in water vapour to form acid, and interacts with other gases and particles in the air to form sulfates and other products that can be harmful to people and their environment ...

We commonly think of pollutants as contaminants that make the environment dirty or impure. A vivid example is sulphur dioxide, a by-product of industrial activity. High levels of sulphur dioxide cause breathing problems. Too much causes acid rain. Sulphur dioxide has a direct effect on health and the environment. Carbon dioxide, on the other hand, is a naturally occuring gas that existed in the atmosphere long before humans. Plants need it to survive. The CO2 greenhouse effect keeps our climate from freezing over. How can CO2 be considered a pollutant?

Potassium (PSO3) Bisulfite Production Systems from Powell are available to produce various weights of potassium bisulfite using 32% to 45% potassium hydroxide and dry sulfur dioxide (SO2) gas, wet sulfur dioxide gas, or liquid sulfur dioxide out of railcars, iso containers, or tank trucks. The systems are automatic and include pumps and heat exchangers for the safe, accurate production of potassium bisulfite. The system can be started by an operator and flow rates can be varied as required. Remote mounted pumps for potassium hydroxide supply and water for dilution of 32 or 45% potassium hydroxide are typical options. A cooling tower with pump is a typical option used for cooling the process.. Many options exist for the equipment such as:. ...

Exposure to an increased level of air pollutants, especially nitrogen dioxide, has been associated with lower likelihoods of successful pregnancy among women undergoing in vitro fertilization, according to a team of fertility researchers.. The team examined the outcomes of the first pregnancy attempt of 7,403 women undergoing IVF at Penn State Milton S. Hershey Medical Center, Hershey, Pa.; Shady Grove Fertility, Rockville, Md.; and Columbia University College of Physicians and Surgeons, New York, N.Y. They conducted their observations over a seven-year period from 2000 to 2007.. Numerous studies have consistently shown a relationship between air pollution and human health, ranging from mortality, cardiovascular disease and other chronic conditions, said Duanping Liao, Ph.D., professor of epidemiology and vice chair department of public health sciences, Penn State College of Medicine. In the process of searching for the mechanisms responsible for the above associations, we, and others, have ...

2001 Quality Assurance Report. EXECUTIVE SUMMARY. Gaseous Monitoring Network The APCD routinely monitors four gaseous pollutants: carbon monoxide (CO), ozone (O3), sulfur dioxide (SO2), and oxides of nitrogen (NOx). Fifty-eight accuracy audits were conducted in 2001. All but three of these audits were within the 10% full-scale analyzer response error considered acceptable by the APCD.. EPA interlaboratory comparisons were conducted during 2001 for carbon monoxide, ozone, sulfur dioxide, and nitrogen dioxide. The ozone comparisons were invalidated due to faulty NPAP equipment. Interlab comparisons are included for 18 gaseous analyzers. All interlab results were within the acceptable EPA performance criterion of 15% error, except one. It was determined that the instrument in question was in need of repair and recalibration.. Overall data recovery for the gaseous monitoring network was 92% in 2001. During this time only one of the analyzers in the APCD network failed to meet the EPA 75% data ...

True flaws, known as objective flaws, occur because of chemical imbalances in the finished products. Wine is primarily of water (80%-90%). The remaining 10%-20% is made up of hundreds or even thousands of different chemical or molecular components. Here, problems may arise. The first type of subjective flaw is off-odors resulting from sulfur compounds. Sulfur has been used since Roman times as a preservative. However, in the wrong concentration, bad things happen. Sulfur dioxide (SO2)* is characterized by a pungent smell of burnt matches, often accompanied by an unpleasant tickling sensation in the nose and throat. The effects of SO2 are directly related to pH. The more acidic the wine, the more pronounced the sulfur dioxide will be. Another compound, hydrogen sulfide (H2S), is characterized by an odor of rotten eggs, resulting from the reduction of elemental sulfur. Yeasts need nitrogen to grow and multiply. In a nitrogen-deficient must, yeasts scavenge for this element by breaking apart amino ...

Top: Photograph of the SO2 camera installation when scientists tested the radio link to the Hawaiian Volcano Observatory (HVO). The camera is aimed at the plume emitting from the Overlook Crater, about 1.4 km away. Under typical trade wind conditions, the plume is blown to the southwest, thus moving from right to left in the imagery. The dashed line indicates the approximate field of view of the instrument. HVO is just off the image to the right. The photograph shows Mauna Loas southern flank in the background. At a distance of more than 20 km, however, this feature is barely visible in the UV imagery even on the clearest of days because UV radiation is scattered significantly more efficiently on air molecules than visible light. Bottom: Example of the imagery displayed at HVO on September 7, 2013 just after a transition between a passive and an active lava lake occurred at 11:21 HST (21:21 UTC). The color scale spans from 0 to 10,000 ppmm. The semicircle represents the closed path along which ...
