Sulfate Anion, SO42-- The sulfate anion in the atmosphere is the result of the oxidation of sulfur dioxide (SO2). The sulfate anion is water soluble and is removed from the atmosphere through precipitation.[Analytica Chimica Acta, v.
sulfate-reducing bacteria
sulfur dioxide (SO2) A pungent, colorless, gaseous pollutant formed primarily by the oxidation of sulfur, such as in anaerobic biological decomposition, and combustion of fossil fuels.
Sulfates: (See Sulfur Oxides.)
> Sulfur Dioxide (SO2): A strong smelling, colorless gas that is formed by the combustion of fossil fuels. Power plants, which may use coal or oil high in sulfur content, can be major sources of SO2.
Iron(III) sulfate or chloride are other common coagulants. They also needs a buffered water, so lime or soda ash is often added to the water.
carbonate, sulfate, chloride and nitrate. Excessive hardness
in water is undesirable because it causes the formation of
soap curds, increased use of soap, deposition of scale in ...
a characteristic of water, imparted by salts of calcium, magnesium, and iron, such as bicarbonates, carbonates, sulfates, chlorides, and nitrates that cause curdling of soap, deposition of scale in boilers, damage in some industrial process, ...
Hardness: characteristic of water which describes the presence of dissolved minerals. Carbonate hardness is caused by calcium and magnesium bicarbonate; noncarbonate hardness is caused by calcium sulfate, calcium chloride, magnesium sulfate, ...
Example; A conjugate of a xenobiotic with some group such as glutathione, sulfate or glucuronic acid, to make it soluble in water or compartmentalized within the cell.

A characteristic of water caused mainly by the salts of calcium and magnesium, such as bicarbonate, carbonate, sulfate, chloride and nitrate.
The clumping together of solids so they can more easily be settled out or filtered out of water. A chemical called aluminum sulfate (alum) is generally used to aid coagulation in water treatment and reclamation.

Hardness (water): Condition caused by dissolved salts of calcium, magnesium, and iron, such as bicarbonates, carbonates, sulfates, chlorides, and nitrates.
In order of decreasing redox potential, these TEAs include nitrate, manganic manganese, ferric iron, sulfate, and carbon dioxide. Microorganisms preferentially utilize electron acceptors that provide the maximum free energy during respiration.
Oxidation of sulfur dioxide produces sulfur trioxide which is the precursor of sulfuric acid which, in turn, is responsible for the sulfate particulate matter emissions.
Anaerobes A group of organisms that do not require molecular oxygen. These organisms, as well as all known life forms, require oxygen. These organisms obtain their oxygen from inorganic ions such as nitrate or sulfate or from protein.

radical : A group of atoms that is capable of remaining unchanged during a series of chemical reactions. Such combinations (radicals) exist in the molecules of many organic compounds; sulfate (SO42-) is an inorganic radical.
The Intergovernmental Panel on Climate Change (IPCC) recently concluded that increased concentrations of greenhouse gases are causing an increase in the Earth's surface temperature and that increased concentrations of sulfate aerosols have led to ...
Electron acceptors are compounds that are relatively oxidized and include oxygen, nitrate, iron (III), manganese (IV), sulfate, carbon dioxide, or in some cases the chlorinated aliphatic hydrocarbons such as tetrachloroethene (PCE), ...
respiration the process during which organisms metabolize food molecules to get energy for growth and maintenance, consuming oxygen, nitrate, sulfate, or another oxidizer and giving off carbon dioxide. ...
Examples: Olancha, Californiaspring (mound)Spring where water emergent at the land surface under artesian flow upward along a fault or fracture where algal material and chemical deposition of dissolved calcium sulfate or calcium carbonate at the ...
