Does all ingested arsenic bioaccumulate in the body, or are small amounts negligible and easily discarded?

Question

Considering that virtually all rice in the US is contaminated with arsenic, it has roused me into asking this question. Each time you consume a bowl of rice, does the arsenic therein circulate into your bloodstream and bioaccumulate permanently into all of your organs, or, if eaten infrequently, is the exposure negligible and low enough, such that the body is unaffected and readily able to excrete the arsenic out without any bioaccumulation occuring?

Answer 1

Most substances are poison if applied in extenso.

Even water is lethal if extensively forced upon body.

The question is: what does extensively mean?

Insignificant doses of arsenic may well be digested,

not accumulated and got rid of naturally, only if applied

as an overdose it is deadly
