  • pollutant
  • Coal-fired power plants are the largest human-caused source of sulfur dioxide, a pollutant gas that contributes to the production of acid rain and causes significant health problems, particularly through its role in forming particulates . (sourcewatch.org)
  • Sulfur dioxide (SO 2 ) 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. (tva.gov)
  • Most of the rest is from burning fossil fuels for industry, but smaller amounts of the pollutant also are released from other industrial processes, such as extracting metal from ore, and the use of high-sulfur fuels by locomotives, ships and non-road equipment. (boulderweekly.com)
  • atmosphere
  • The blue auroral glows of Io's upper atmosphere are caused by volcanic sulfur dioxide. (wikipedia.org)
  • The atmosphere of Io , a natural satellite of Jupiter , is 90% sulfur dioxide and trace amounts are thought to also exist in the atmosphere of Jupiter . (wikipedia.org)
  • Yaguang Luo and William Conway from the USDS ARS, in collaboration with Liping Kou, Wu Ding, and Xinghua Liu from China's Northwest A&F University, recently published a report in HortScience that explored alternatives to sulfur dioxide for maintaining quality of table grapes, including various combinations of rachis removal, chlorinated wash, hot water treatment, and modified atmosphere packaging.

  • acid rain
  • Sulfur dioxide contributes to the formation of acid rain, which damages forests, crops, and buildings, and acidifies lakes, streams, and rivers, making them unsuitable for aquatic plant and animal life. (sourcewatch.org)
  • A known health hazard and contributor to acid rain, sulfur dioxide (SO 2 ) is one of six air pollutants regulated by the U.S. Environmental Protection Agency (EPA). (nasa.gov)
  • decay
  • Although natural processes like volcanic activity and biological decay are responsible for half of the world's atmospheric sulfur, emissions caused by human activity far exceed natural emissions in the developed countries. (tva.gov)
  • Because of its effectiveness in delaying stem browning and decay, sulfur dioxide gas (SO2) is currently the treatment of choice in many countries for prolonging shelf life of grapes. (scienceblog.com)
  • According to the Kou, a visiting scientist from China and the study's lead researcher, the hot water treatment resulted in significantly higher oxygen retention and lower carbon dioxide accumulation in packages, firmer texture, higher overall visual quality, lower decay rate, and lower microbial populations than other treatments or commercially packed grapes.

  • concentration
  • 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. (pakobserver.net)
  • According to European and Russian regulations it is allowed not to indicate on the labels the presence of sulfur dioxide in beverages if its concentration is less than 10 mg/L. (environmental-expert.com)
  • respiratory
  • Animal studies also show respiratory effects from breathing sulfur dioxide. (cdc.gov)
  • Sulfur dioxide and other air pollutants have been reported to contribute to or aggravate acute, nonspecific diseases of the upper respiratory tract, chronic bronchitis, emphysema, and lung cancer (3). (cdc.gov)
  • NIOSH
  • Although the current permissible exposure limit promulgated by the Occupational Safety and Health Administration standard is 5 ppm for an 8-hour time-weighted average (TWA) exposure (7), based on available scientific information, NIOSH recommends that occupational exposures to sulfur dioxide not exceed an 8-hour TWA of 0.5 ppm (4). (cdc.gov)
  • refrigerant
  • 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 1940's. (hvac-talk.com)
  • methyl
  • My father got into the refrigeration business back in 1942 when the flavors of the day were the 'new' R12 Freon, sulfur dioxide and methyl chloride for most all domestic and light commercial work. (hvac-talk.com)
  • Environmental
  • The U.S. Environmental Protection Agency (EPA) is issuing a final new health standard for sulfur dioxide (SO2). (environmental-expert.com)
  • The monitors tested were the DuPont air monitoring badges, the 3M sulfur-dioxide monitor, Mine Safety Appliances (MSA) Vapogard dosimeter tubes, Reiszner Environmental and Analytical Laboratories (REAL) badges and the REAL badges with water. (cdc.gov)
  • To comply with environmental regulations in the production of low-level sulfur fuel, it is necessary to get reliable information about the product quality and sulfur content. (environmental-expert.com)
  • In the mid-2000`s, the Environmental Protection Agency (EPA) began a program to greatly reduce the amount of Sulfur in petroleum products. (environmental-expert.com)
  • adults
  • Children who live in or near heavily industrialized areas where sulfur dioxide occurs may experience difficulty breathing, changes in the ability to breathe deeply, and burning of the nose and throat It is not known whether children are more vulnerable to these effects than adults. (cdc.gov)
  • However, children may be exposed to more sulfur dioxide than adults because they breathe more air for their body weight than adults do. (cdc.gov)
  • climate
  • Using a new satellite-based method, scientists from NASA, Environment and Climate Change Canada , and two universities have located 39 unreported and major manmade sources of sulfur dioxide emissions. (nasa.gov)
