TLDR
Flatfish, mainly in the form of plaice, and crustacea were found to be the main source of organic arsenic compounds, which gave rise to elevated concentrations of arsenic in the urine of human subjects from two cities in Sweden.About:

Journal ArticleDOI
Exposure to inorganic arsenic metabolites during early human development.
TL;DR: The increased methylation in late gestation was associated with lower arsenic concentrations in blood and higher concentrations in urine, compared with a few months postpartum, and may indicate that methylation of arsenic is increased during pregnancy and that DMA is the major form of arsenic transferred to the fetus.

A unique metabolism of inorganic arsenic in native Andean women
Marie Vahter,Gabriela Concha,Barbro Nermell,Robert Nilsson,Fernando Noel Dulout,Adayapalam T. Natarajan +5 more
TL;DR: The metabolism of inorganic arsenic (As) in native women in four Andean villages in north-western Argentina with elevated levels of As in the drinking water has been investigated, and arsenic was excreted in the urine mainly as inorganic As and DMA.
Journal ArticleDOI
Metabolism of inorganic arsenic in children with chronic high arsenic exposure in northern Argentina.
TL;DR: Interestingly, the children had a significantly higher percentage of inorganic As in urine than the women, and the percentage of DMA increased with increasing U-Asmet, indicating an induction of As methylation with increasing exposure.
Journal ArticleDOI
Altered profile of urinary arsenic metabolites in adults with chronic arsenicism. A pilot study.
Del Razo Lm,Gonzalo G. García-Vargas,Vargas H,Arnulfo Albores,María E. Gonsebatt,Regina Montero,Patricia Ostrosky-Wegman,M. Kelsh,Mariano E. Cebrián +8 more
TL;DR: Relationships between alterations in the profile of urinary arsenic (As) species and the presence of cutaneous signs of arsenicism were studied in Region Lagunera, Mexico to confirm the potential relationship between metabolic alterations and overt signs of As toxicity.

Cytogenetic effects in human exposure to arsenic
María E. Gonsebatt,Libia Vega,Ana María Salazar,Regina Montero,Patricia Guzman,J. Blas,L.M. Del Razo,Gonzalo G. García-Vargas,Arnulfo Albores,Mariano E. Cebrián,M. Kelsh,Patricia Ostrosky-Wegman +11 more
TL;DR: The type of cytogenetic damage observed gives evidence of arsenic as a clastogenic/aneugenic carcinogen in rural populations that live in the same geographical area and have similar socioeconomic status, but different degree of exposure to inorganic arsenic via drinking water.

Comparison of the Urinary-excretion of Arsenic Metabolites After a Single Oral Dose of Sodium Arsenite, Monomethylarsonate, Or Dimethylarsinate in Man
TL;DR: The urinary elimination of the metabolites of arsenic has been followed up as a function of time in volunteers who ingested a single oral dose of arsenic either as sodium arsenite (Asi), monomethylarsonate (MMA), or cacodylate (DMA).
Journal ArticleDOI
Endogenous creatinine in serum and urine.
TL;DR: There is a gradual rise in the serum concentration and in the rate of urinary excretion of creatinine from one month of age to puberty, when adult levels are reached.
Journal ArticleDOI
Methylated Forms of Arsenic in the Environment
TL;DR: Environmental samples were analyzed for arsenate and arsenite ions and the methylarsenic acids in nanogram amounts and Dimethylarsinic acid and methylarsonic acid were found in natural waters, bird eggshells, seashells, and human urine.

Chronic Arsenic Poisoning in the North of Mexico
TL;DR: Non-specific symptoms were more prevalent in the exposed population and they occurred more frequently in those individuals with skin signs, and the relative risk of suffering a particular manifestation of poisoning, ranged from 1.9 to 36 times higher in the exposure population.
