Thallium was an effective murder weapon before its effects became understood and an antidote (Prussian blue) was discovered. [7] Thallium is often imported for products like optical lenses and electronics. The US has not manufactured thallium since 1984.
The sulfate or sulphate ion is a polyatomic anion with the empirical formula SO 2− 4. Salts, acid derivatives, and peroxides of sulfate are widely used in industry. Sulfates occur widely in everyday life. Sulfates are salts of sulfuric acid and many are prepared from that acid.
The suggested safe level of copper in drinking water for humans varies depending on the source, but tends to be pegged at 1.3 mg/L. [2] So low is the toxicity of copper that copper(II) sulfate is a routine reagent in undergraduate chemistry laboratories.
Mercury poisoning is a type of metal poisoning due to exposure to mercury. [3] Symptoms depend upon the type, dose, method, and duration of exposure. [3] [4] They may include muscle weakness, poor coordination, numbness in the hands and feet, skin rashes, anxiety, memory problems, trouble speaking, trouble hearing, or trouble seeing. [1]
While humans have been able to adapt to higher levels of concentrations with time, some effects of ingestion of sulfur water has found to have cathartic effects on people consuming water with sulfate concentrations of 600 mg/litre according to a study from the US Department of health in 1962.
The effect of major volcanic eruptions on sulfate aerosol concentrations and chemical reactions in the atmosphere Major volcanic eruptions have an overwhelming effect on sulfate aerosol concentrations in the years when they occur: eruptions ranking 4 or greater on the Volcanic Explosivity Index inject SO 2 and water vapor directly into the ...
Chondroitin sulfate is an important structural component of cartilage, [2] and provides much of its resistance to compression. [3] Along with glucosamine, chondroitin sulfate has become a widely used dietary supplement for treatment of osteoarthritis, although large clinical trials failed to demonstrate any symptomatic benefit of chondroitin.
Cultures of sulfate reducing bacteria grown without the presence of sulfate will not methylate mercury. It is a possibility that the respiration of these cells is coupled to mercury methylation. [2] The Acetyl-CoA pathway for mercury methylation is done by sulfate reducing bacteria and is catalyzed by a corrinoid dependent protein. Through this ...
