There is a demonstrable association between exposure to air pollutants and deaths due to cardiovascular diseases. The objective of this study was to estimate the effects of exposure to sulfur dioxide on mortality due to circulatory diseases in individuals 50 years of age or older residing in São José dos Campos, SP. This was a time-series ecological study for the years 2003 to 2007 using information on deaths due to circulatory disease obtained from Datasus reports. Data on daily levels of pollutants, particulate matter, sulfur dioxide (SO2), ozone, temperature, and humidity were obtained from the São Paulo State Environmental Agency. Moving average models for 2 to 7 days were calculated by Poisson ...
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 ...
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. ...

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 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 ...

Sulfur dioxide irritates the skin and mucous membranes of the eyes, nose, throat, and lungs. High concentrations of SO2 can cause inflammation and irritation of the respiratory system, especially during heavy physical activity. The resulting symptoms can include pain when taking a deep breath, coughing, throat irritation, and breathing difficulties. High concentrations of SO2 can affect lung function, worsen asthma attacks, and worsen existing heart disease in sensitive groups. This gas can also react with other chemicals in the air and change to a small particle that can get into the lungs and cause similar health effects ...

Sulphur dioxide (E220) and other sulphites (E221, E222, E223, E224, E226, E227 and E228) are used as preservatives in a wide range of foods, especially soft drinks, sausages, burgers, and dried fruits and vegetables.. Sulphur dioxide is produced naturally when wine and beer are made, and is sometimes added to wine. Anyone who has asthma or allergic rhinitis may react to inhaling sulphur dioxide. A few people with asthma have had an attack after drinking acidic drinks containing sulphites, but this isnt thought to be very common.. Food labelling rules require pre-packed food sold in the UK, and the rest of the European Union, to show clearly on the label if it contains sulphur dioxide or sulphites at levels above 10mg per kg or per litre. ...

The Tilston air quality monitoring program, which was first started in July 1998, had developed and expanded since that time as additional air quality issues arose. The program was developed in consultation with the Tilston Community Advisory Group (CAG). At the start of the monitoring program in July 1998, Manitoba Conservation only conducted limited outdoor air monitoring for sulphur dioxide in W. Campbells farm yard (Farm Yard #1) in the Rural Municipality of Albert (9-6-29). This monitoring location was 1.6 km (1 mile) directly east of the Tundra Oil and Gas Ltd. oil battery located at 8-8-6-29 W.P.M. (the battery). The air quality monitoring program was expanded in early 1999 because of additional questions that had arisen regarding the air quality in the area. The sulphur dioxide monitor was re-located from its original location at W. Campbells farm to a monitoring trailer on J. Andersons farm yard (Farm Yard #2) about 1 km south at 4-6-29 W.P.M. This new location was selected in ...

Robust cloud products are critical for DSCOVR to make a significant contribution to climate studies. Building on our teams track-record in cloud detection, cloud property retrieval, oxygen band exploitation, and DSCOVR-related studies, we propose to develop a suite of algorithms for generating the operational EPIC cloud mask, cloud height and cloud optical thickness products. Multichannel observations will be used for cloud masking; the cloud height will be developed with information from the oxygen A- and B- band pairs (780 nm vs. 779.5 nm and 680 nm vs. 687.75 nm); for the cloud optical thickness retrieval, we propose an approach that combines the EPIC 680 nm observations and numerical weather model outputs. Preliminary results from radiative transfer modeling and from proxy data applications show that the proposed algorithms are viable. Product validation will be conducted by comparing EPIC observations/retrievals with counterparts from coexisting Low Earth Orbit (LEO) and Geosynchronous ...
