BACKGROUND It is generally acknowledged that the determination of harmful chemical compounds excreted into saliva is useful for assessing their exposure levels. The aim of the present study was to compare the total arsenic and its species in saliva and urine samples collected from the people residing in an arsenic-contaminated area of China and to further verify the feasibility of using salivar...

The presence of arsenic in marine samples was first reported over 100 years ago, and shortly thereafter it was shown that common seafood such as fish, crustaceans, and molluscs contained arsenic at exceedingly high concentrations. It was noted at the time that this seafood arsenic was probably present as an organically bound species because the concentrations were so high that if the arsenic ha...

The concentrations of four chemical species of arsenic in urine were observed with time, after ingestion of three different chemical species of arsenic. The arsenic-rich substances ingested, including arsenite-rich wine, arsenate-rich drinking water, and crab meat which contained organo-arsenic compounds. After ingestion of arsenite-rich wine, approximately 10% of the arsenic was excreted as ar...

The importance of arsenic detection techniques has received significant attention of researchers during recent years due to its carcinogenic effects on human health through drinking water even at low concentration. There are various arsenic detection techniques used in laboratory that have detection limit below 1μg/L viz., Hydride Generation Atomic Absorption Spectroscopy (HGAAS), Graphite Furn...

Epidemiological evidence shows an association between inorganic arsenic in drinking water and increased risk of skin, lung and bladder cancers. The lack of animal models has hindered mechanistic studies of arsenic carcinogenesis in the past, but some promising new models for these cancers are now available. The various forms of arsenic to which humans are exposed, either directly or via metabol...

Since Babagorgorfountain in the Ghorveh city of Kurdistan province is located in the arsenic belt of Iran, to raise awareness about the quality of drinking water from this fountain the concentration of arsenic and other heavy metals as well as other physicochemical parameters were investigated to protect the public health. In this study, water samples were collected from Babagorgorfountain. Ars...

given in sufficient quantity without causing poisonous effect on the host. On the other hand, the organic compounds in which arsenic is combined with carbon appear to have the effect of reducing its toxicity, thus enabling more of the element to be given with correspondingly enhanced therapeutic activity. One of the first of these compounds that were tried was atoxyl, it proved useful in syphil...
