In the study, Kevin
Francesconi and colleagues point out that drinking water in many parts of the
world, including some regions of the United States, contain amounts of
arsenic that exceed the World Health Organization’s maximum acceptable levels.
Consumption of seafood, the article notes, is another major source of arsenic
contamination. Health effects from chronic arsenic exposure include skin and
internal cancers, cardiovascular disease, and possibly diabetes, it
scientists describe monitoring arsenic excretion in the urine of human
volunteers. They found that ability to eliminate arsenic from the body varied
greatly, with some participants excreting up to 95 percent of the ingested
arsenic but others eliminating as little as four percent. “This observed
individual variability in handling [arsenic] exposure has considerable
implications for the risk assessment of arsenic ingestion,” the paper states.
It adds that further study is needed to assess potential risks to humans
consuming seafood products. “The data presented here suggest that the long held
view that seafood arsenic is harmless because it is present mainly as
organoarsenic compounds needs to be reassessed.”
