Jan 09, 2017· Sulfates. Salts, acid derivatives, and peroxides of sulfate are widely used in industry. Sulfates also occur widely in everyday life. Sulfates are salts of sulfuric acid and many are prepared from that acid. Sulfates are very important molecules for everyone's health and do not cause allergic or sensitivity reactions....
Corporate Personhood and Sulfide Mining in Anishinaabeg ...
But sulfates, which are released through the sulfide mining process, enter into rivers and lakes. The sulfates drift into the sediment where they convert into hydrogen sulfide that enters the root system of manoomin. Concentrations of sulfates that are over 10 parts per million of sulfate impairs the growth of manoomin resulting in...
