A variety of studies indicated that inorganic arsenic and its methylated metabolites have
paradoxical effects, namely, carcinogenic and anticancer effects. Epidemiological studies …

This paper reviews the current knowledge on the toxicity, speciation and biogeochemistry of
arsenic in aquatic environmental systems. The toxicity of arsenic is highly dependent on the …

Arsenic is a worldwide environmental pollutant and a human carcinogen. It is well
recognized that the toxicity of arsenicals largely depends on the oxidoreduction states …

The metabolism of arsenic is generally accepted to proceed by repetitive reduction and
oxidative methylation; the latter is mediated by arsenic methyltransferase (Cyt19). In human …

Monomethylarsonic acid (MMA V) and dimethylarsinic acid (DMA V) are active ingredients in
pesticidal products used mainly for weed control. MMA V and DMA V are also metabolites of …

The occurrence of a large number of diverse arsenic species in the environment and in
biological systems makes it important to compare their relative toxicity. The toxicity of arsenic …

Long-term exposure to ingested inorganic arsenic is associated with peripheral vascular
disease (PVD) in the blackfoot disease (BFD)-hyperendemic area in Taiwan. This study …

To gain insight into plant responses to arsenic, the effect of arsenic exposure on maize (Zea
mays L.) root proteome has been examined. Maize seedlings were fed hydroponically with …

Carbon nanotubes (CNTs) are emerging nanotechnology materials which are likely to be
mass-produced in the near future. However, prior to mass-production, certain health-related …

The biologic effects of inorganic arsenic predominantly involve reaction of the trivalent forms
with sulfhydryl groups in critical proteins in target cells, potentially leading to various …
