Inorganic arsenic (As) is considered as a human carcinogen because it is associated with cancers of skin, lung, liver and bladder in exposed population. Consumption of As contaminated ground water for long term causes oxidative stress. Generation of reactive oxygen
Samantha L Goggin et al.
Neurotoxicology, 33(5), 1338-1345 (2012-09-11)
Over the past two decades, key advancements have been made in understanding the complex pathology that occurs following not only high levels of arsenic exposure (>1 ppm) but also levels previously considered to be low (<100 ppb). Past studies have

Biological trace element research, 150(1-3), 451-459 (2012-08-15)
The objective of the present study was to investigate if arsenic exposure results in glutathione efflux from human erythrocytes. Arsenite significantly depleted intracellular nonprotein thiol level in a time- and concentration-dependent manner. The intracellular nonprotein thiol level was decreased to
