  • To limit the emission of compounds of sulfur from combustion of fuels. (ca.gov)
  • 110.8 The burning and incineration of sewage treatment plant waste gases provided that the fuel used to incinerate such gases does not contain sulfur or sulfur compounds in excess of the amounts specified in Section 301. (ca.gov)
  • A person shall not burn any gaseous fuel containing sulfur compounds in excess of 1.14 grams per cubic meter (50 grains per 100 cubic feet) of gaseous fuel, calculated as hydrogen sulfide at standard conditions, or any liquid fuel or solid fuel having a sulfur content in excess of 0.5% by weight. (ca.gov)
  • Minerals
  • The sulfur cycle is the collection of processes by which sulfur moves to and from minerals (including the waterways)[clarification needed] and living systems. (wikipedia.org)
  • Minerals such as pyrite (FeS2) comprise the original pool of sulfur on earth. (wikipedia.org)
  • dioxide pollution
  • Long-term studies surveying large numbers of children indicate that children who have breathed sulfur dioxide pollution may develop more breathing problems as they get older, may make more emergency room visits for treatment of wheezing fits, and may get more respiratory illnesses than other children. (cdc.gov)
  • In 2010, plant experts, scientists, environmentalists and ranchers said they believe sulfur dioxide pollution from coal-fired power plants is slowly killing vegetation across Texas. (sourcewatch.org)
  • 1995
  • Asphalt concrete, similar aggregate material using 'bitumen' as a binder Lunarcrete: Sulfur based "Waterless Concrete", for proposals for its use as a lunar construction material Brandt, Andrzej Marek (1995). (wikipedia.org)
  • mainly of sulfur
  • Grandma's "spring tonic" consisted mainly of sulfur and molasses. (healthy.net)
  • Sulfur concrete is a composite construction material, composed mainly of sulfur and aggregate (generally a coarse aggregate made of gravel or crushed rocks and a fine aggregate such as sand). (wikipedia.org)
  • sulfates
  • Sulfur is also available as various sulfates or sulfides. (healthy.net)
  • Prior to falling to the earth, sulfur dioxide and nitrogen oxide gases and their particulate matter derivatives-sulfates and nitrates-contribute to visibility degradation and harm public health. (sourcewatch.org)
  • trioxide
  • In perfectly dry apparatus, sulfur trioxide vapor is invisible, and the liquid is transparent. (wikipedia.org)
  • The electrical dipole moment of gaseous sulfur trioxide is zero. (wikipedia.org)
  • Liquid sulfur trioxide has a vapor pressure consistent with the gamma form. (wikipedia.org)
  • Sulfur trioxide can be prepared in the laboratory by the two-stage pyrolysis of sodium bisulfate. (wikipedia.org)
  • Sulfur trioxide will cause serious burns on both inhalation and ingestion because it is highly corrosive and hygroscopic in nature. (wikipedia.org)
  • oxide
  • Acid rain is rain saturated with chemicals like sulfur dioxide and nitrogen oxide, which causes acidification of lakes and streams and contributes to the damage of trees at high elevations and many sensitive forest soils. (sourcewatch.org)
  • Congress passed more amendments to the Clean Air Act in 1990, including Title IV, which addressed the problem of acid rain by curbing sulfur dioxide and nitrogen oxide emissions. (sourcewatch.org)
  • protein
  • Sulphur is thus considered fundamentally important to human health, and conditions such as nitrogen imbalance and protein-energy malnutrition may result from deficiency. (wikipedia.org)
  • But overall, sulfur is most important as part of protein. (healthy.net)
  • the resulting sulfur deficiency is difficult to differentiate clinically from protein deficiency, which is of much greater concern. (healthy.net)
  • Sulfur is also present in keratin, which is necessary for the maintenance of the skin, hair, and nails, helping to give strength, shape, and hardness to these protein tissues. (healthy.net)
  • Sulfur, in its various forms, is important to the yeast in protein biosynthesis as well as vitamins and coenzymes. (springer.com)
  • Protein which binds at least one iron-sulfur cluster, e.g. 2Fe-2S, 3Fe-4S, 4Fe-4S. (uniprot.org)
