Description

Descrição geral

Sulfur is present in abundant quantities in marine and freshwater sediments. It exists in the form of various sulfur compounds such as pyrite, acid volatile sulfides, elemental sulfur, sulfates and organic sulfur.Quantitative estimation of reduced inorganic sulfur compounds in modern sediments and shales by a chromium reduction technique has been described.
Sulfur is naturally present in cysteine and methionine amino acids, which can be detected by inductively coupled plasma mass spectrometry(ICP-MS). It is also an important element required for plant growth, since it is useful in lowering the pH of the soil.
