Seafood, including finfish, shellfish, and seaweed, is the largest contributor to arsenic (As)
exposure in many human populations. In contrast to the predominance of inorganic As in …

Arsenic is a metalloid that occurs naturally in aquatic and terrestrial environments. The high
toxicity of arsenic derivatives converts this element in a serious problem of public health …

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 …

Diet, especially seafood, is the main source of arsenic exposure for humans. The total
arsenic content of a diet offers inadequate information for assessment of the toxicological …

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 …

Background Speciation analysis is essential when evaluating risks from arsenic (As)
exposure. In an oral exposure scenario, the importance of presystemic metabolism by gut …

Inorganic arsenic (iAs) at high exposures is a human carcinogen, affecting mainly the
urinary bladder, lung and skin. We present an assessment of the mode of action (MOA) of …

Microbe-mediated arsenic (As) methylation is enhanced when paddy soils are flooded,
producing primarily dimethylarsinic acid (DMA) that is phytotoxic and can induce rice …

Trace element-contaminated soils (TECSs) are one of the consequences of the past
industrial development worldwide. Excessive exposure to trace elements (TEs) represents a …
