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?

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).
