TLDR
In this article, a high performance liquid chromatography inductively coupled plasma mass spectrometry (HPLC-ICP-MS) system for speciation of arsenite, arsenate, monomethyl arsonic acid (MMAA), dimethyl arsenic acid (DMAA) and arsenobetaine (AB) in urine samples has been developed.About:

Identification of dimethylarsinous and monomethylarsonous acids in human urine of the arsenic-affected areas in West Bengal, India.
TL;DR: A speciation technique for arsenic has been developed using an anion-exchange high-performance liquid chromatography/inductively coupled argon plasma mass spectrometer (HPLC/ICP MS) and was applied to determine arsenic species in urine samples from three arsenic-affected districts of West Bengal, India.

Arsenic speciation and toxicity in biological systems.
TL;DR: Overall, it appears that contamination of water by As is probably more harmful to humans than As in food grains or vegetables, because As bioavailability in water is generally higher than its bio availability in food.

TL;DR: The results suggest that MMA(III) (GS)(2) is highly toxic compared to other arsenic compounds because of faster accumulation of this species by cells, in addition to having the toxic nature of methylated trivalent organic arsenics.

TL;DR: The evidence assessed here indicates that arsenic can also cause liver, lung, kidney, and bladder cancer and that the population cancer risks due to arsenic in U.S. water supplies may be comparable to those from environmental tobacco smoke and radon in homes.

Cancer potential in liver, lung, bladder and kidney due to ingested inorganic arsenic in drinking water.
TL;DR: A significant dose-response relationship was observed between arsenic level in drinking water and mortality of the cancers, and the multiplicity of inorganic arsenic-induced carcinogenicity without showing any organotropism deserves further investigation.

Dose-response relation between arsenic concentration in well water and mortality from cancers and vascular diseases
TL;DR: A significant dose-response relation was observed between arsenic levels in well water and cancers of the bladder, kidney, skin, and lung in both males and females, and cancers in the prostate and liver in males, but there was no association for cancer of the nasopharynx, esophagus, stomach, colon, and uterine cervix.
