Organoarsenic chemistry WikipediaArsenic occurrence toxicity and speciation techniques
Organoarsenic chemistry is the chemistry of compounds containing a chemical bond between arsenic and carbonA few organoarsenic compounds also called organoarsenicals are produced industrially with uses as insecticides herbicides and fungicidIn general these applications are declining in step with growing concerns about their impact on the environment and human healthSpectrometric methods for the determination of arsenic involve the use of various spectrometric techniques such as UV visible atomic absorption atomic emission hydride generation graphite furnace etc The most widely accepted procedures for the analysis of total arsenic exploit the reduction of arsenic compounds to gaseous arsine

Arsenic induced abnormalities in glucose metabolism Environmental Arsenic Exposure and Diabetes
Arsenic is a toxic heavy metal and belongs to the 5 th group in the periodic table It is present in both inorganic and organic forms in different surroundings and its level is increased by anthropogenic contamination It is a ubiquitous element and is found in four oxidation states 3 0 3 and 5arsenic exposure is ascertained at an individual level using total urinary arsenic The authors have taken considerable effort to isolate the effect of inorganic arsenic by control ling for nontoxic arsenic species that could influence uri nary arsenic levels from the consumption of seaweed fish or shellfish
