Bioconcentration of Arsenic in Hediste diversicolor

What is it about?

This study focused on bioconcentrations of arsenic inHediste diversicolor after exposure to three different molecule solutions: arsenate, dimethylarsinate and arsenobetaine. Speciation analysis was carried out after exposing the organisms to these solutions in order to investigate their arsenic biotransformation capacity.

Why is it important?

H. diversicolor shows a high bioconcentration capacity of As in tissues and thus appears to show a wide range of possible physiological detoxification mechanisms.

Based on our results, it is plain that H. diversicolor may represent an important bioindicator species for ecotoxicological studies on arsenic speciation and accumulation.
