As(III), As(V), monomethyl arsonic acid, and dimethylarsenic acid, which gives a quick and reliable estimation of exposure to inorganic arsenic.

Induction of cancer appears to be the most striking long-term effect of chronic exposure to inorganic arsenic. Epidemiological studies have demonstrated an evident causal relationship between environmental, occupational, and medicinal exposure of man to inorganic arsenic and cancer of the skin and lungs (NAS 1977, Fowler 1977, Leonard 1984, lARC 1987, Cantor 1997, Hayes 1997).

Of the agents listed, lead is most likely to cause a decrease in heme biosynthesis. Exposure to inorganic arsenic may also cause anemia. The urinary concentrations of lead before and after EDTA treatment may confirm the diagnosis. The answer is (C). 

Arsenic concentrations in hair and nails have been used as indicators of exposure to inorganic arsenic (112,113,121,122). However, arsenic in hair might be influenced by surface contamination via dust, water, soaps, and shampoos. Data on arsenic speciation in hair and nails is sparse. Only two studies reported the presence of dimethylated arsenic species in hair and nails (119,120).
