(1) Inorganic anions such as chloride, nitrate and sulphate can be separated in about five minutes.(2) The respirable portion of particulates can include acid condensates, sulfates , nitrates, and organic compounds.(3) Tiny particles of soot or chemical compounds like sulphates reflect sunlight and they also promote the formation of bigger, longer lasting clouds.(4) The magnesium corrosion control rod present in many hot water heaters can chemically reduce naturally occurring sulfates to hydrogen sulfide.(5) Herbicides include a wide range of compounds, such as common salt, sulfates , and ammonium and potassium salts.(6) Other contaminants include arsenic, chromium, cyanides, phenols, sulphates , gases and ├ö├ç├┐combustible materials├ö├ç├û.(7) The Podolia ash beds consist largely of clay minerals accompanied by a variety of primary volcanogenic crystals and secondary sulphides, sulphates , oxides, carbonates, and silicates.(8) The oils are first reacted with sulfuric acid, which converts them into sulfates .(9) The technique can identify iron-bearing phases (such as oxides, silicates, sulfides, sulfates , and carbonates), as well as the amount of iron in each phase and the presence of iron in various oxidation states.(10) These minerals can be supplemented in the diet as inorganic oxides, sulfates , or organic chelates with the mineral bound to an amino acid or peptide complex.(11) They are immediately downwind of coal-burning electric plants in the Ohio and Tennessee valleys, and their high elevation makes them extremely susceptible to sulfates and nitrates moving through the atmosphere.(12) Biodiesel reduces emissions of unburned hydrocarbons, carbon monoxide, sulfates , polycyclic aromatic hydrocarbons, nitrated polycyclic aromatic hydrocarbons and particulates.(13) Black smokers, debouching fluids at 350Ôö¼ÔûæC into the overlying sea water sit atop a mound of hydrothermal minerals, including sulphides, sulphates , oxides, and silicates.(14) Oxygen levels also had significant effects on ocean chemistry: increasing continental weathering rates and providing sulfates and nitrates as nutrients.(15) Common among these are bicarbonates, calcium, chlorides, fluorides, magnesium and sulfates - all of which can cause salt stress if found in excessive amounts.(16) Organic sulfates are esters and are formed by reacting an alcohol with cold sulfuric acid or by the reaction of sulfuric acid with a double bond in an alkene.
