The Determination of Arsenic in Official Arsenicals*†
Journal of the American Pharmaceutical Association (Scientific ed.), 1947Abstract An assay for the determination of arsenic is presented which is applicable to six of the seven Pharmacopoeial arsenicals. The method employs an alkali‐acid permanganate oxidation for the destruction of organic matter.

Arsenate detoxification in a Pseudomonad hypertolerant to arsenic
Archives of Microbiology, 2006Pseudomonas sp. strain As-1, obtained from an electroplating industrial effluent, was capable of growing aerobically in growth medium supplemented with up to 65 mM arsenate (As (V)), significantly higher concentrations than those tolerated by other reference arsenic resistant bacteria. The majority of the arsenic was detected in culture supernatants as

Arsenic poisoning continues to require awareness of its diverse clinical manifestations. Industry is the major source of arsenic exposure. Although epidemiologic studies strongly contend that arsenic is carcinogenic, there are little supportive research data.

Atherosclerosis, 2000
Epidemiological studies have demonstrated a correlation between environmental or occupational arsenic exposure and a risk of vascular diseases related to atherosclerosis. Studies summarized in this review suggest that arsenic induces endothelial dysfunction, including inflammatory and coagulating activity as well as impairs nitric oxide (NO) balance ...

Arsenic excretion by monkeys dosed with arsenic-containing fish or with inorganic arsenic
Bulletin of Environmental Contamination and Toxicology, 1978Four adult female Cynomolagus monkeys were given single oral dose of fish arsenic. 67% of the arsenic was excreted with the urine and 10% with the feces, essentially within 5 days post exposure. The same monkeys were later dosed with inorganic arsenic and 76% of it was excreted with the urine, and practically nil with the feces.

Arsenic and arsenic health effects
AIP Conference Proceedings, 2019Arsenic (As) is a common, naturally occurring drinking water contaminant, that originates from As-containing rocks and soil and is transported to natural waters through erosion and dissolution. Chronic As poisoning has become a worldwide public health issue.

Arsenophobia has held sway over civilized governments throughout this century. Because of the still unproven association between arsenic (As) and cause of cancer, arsenophobia has gained strength to the point that many safe uses of arsenicals have been abandoned. Even the production of arsenic trioxide (AS2O3) is in jeopardy.
