Westernized diets lower arsenic gastrointestinal bioaccessibility but increase microbial arsenic speciation changes in the colon.
TLDR
Dietary background is a crucial parameter to incorporate when predicting bioavailability with bioaccessibility measurements and when assessing health risks from As following oral exposure.About:

Nutritional status affects the bioaccessibility and speciation of arsenic from soils in a simulator of the human intestinal microbial ecosystem.
TL;DR: The results indicated that the vitamin C and protein powder increased As bioaccessibility in gastric digests and significantly decreased As methylation with the addition of glucose, which enhanced the reduction of As(V).

Refining health risk assessment of heavy metals in vegetables from high geochemical background areas: Role of bioaccessibility and cytotoxicity
TL;DR: Wang et al. as mentioned in this paper conducted a systematic study of heavy metal levels, bioaccessibilities, and gastrointestinal cytotoxicity in two popular consumed vegetables mint and pea sprouts from three major producing cities in Yunnan, Southwest China were conducted for evaluating potential health risk to local inhabitants.
Journal ArticleDOI
A novel approach to converting alkylated arsenic to arsenic acid for accurate ICP-OES determination of total arsenic in candidate speciation standards
TL;DR: A new approach was developed for quantitatively converting alkylated arsenic to arsenic acid (AsV) using microwave assistance as discussed by the authors, which was used in the development of a new series of organic As reference materials, SRMs 3030, 3031, 3033 and 3034, for monomethylarsonic acid, dimethylarsinic acid, arsenobetaine and arsenocholine, respectively.
Journal ArticleDOI
Improving the predictive value of bioaccessibility assays and their use to provide mechanistic insights into bioavailability for toxic metals/metalloids – A research prospectus
TL;DR: In this paper, only a portion of orally ingested metal(loid) contaminants are bioavailable, which poses a significant public health concern, since only a small portion of ingested metal contaminants can be bioavailable.

Arsenic contamination of Bangladesh paddy field soils: implications for rice contribution to arsenic consumption.
Andrew A. Meharg,M.m. Rahman +1 more
TL;DR: Assessment of arsenic levels in paddy soils throughout Bangladesh showed that arsenic levels were elevated in zones where arsenic in groundwater used for irrigation was high, and where these tube-wells have been in operation for the longest period of time.
Journal ArticleDOI
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.

Greatly enhanced arsenic shoot assimilation in rice leads to elevated grain levels compared to wheat and barley
Paul N. Williams,Antia Villada,Claire Deacon,Andrea Raab,Jordi Figuerola,Andy J. Green,Joerg Feldmann,Andrew A. Meharg +7 more
TL;DR: Investigation of variation in the assimilation and translocation of arsenic in commercially farmed temperate rice, wheat, and barley found that the risk posed by As in the human food-chain needs to be considered in the context of anaerobic verses aerobic ecosystems.

Arsenic poisoning in the Ganges delta
S. K. Acharyya,P. Chakraborty,Saibendu Kumar Lahiri,B. C. Raymahashay,Saumyen Guha,Amitava Bhowmik +5 more
TL;DR: Observations indicate that arsenic- rich pyrite and other arsenic minerals, which were proposed in previous models to give rise to arsenic pollution, are rare or even absent in the sediments of the Ganges delta.

An in vitro gastrointestinal method to estimate bioavailable arsenic in contaminated soils and solid media
TL;DR: In this paper, a method was developed to simulate the human gastrointestinal environment and to estimate bioavailability of arsenic in contaminated soil and solid media, where arsenic was sequentially extracted from contaminated soil with simulated gastric and intestinal solutions.
