Arsenic in Hediste diversicolor
What is it about?
This study focused on the exposure of the common ragworm Hediste diversicolor(Müller 1776) to sediments enriched with different arsenic compounds, namely arsenate, dimethyl-arsinate, and arsenobetaine. Speciation analysis was carried out on both the spiked sediments and the exposed polychaetes in order to investigate H. diversicolor capability of arsenic bioaccumulation and biotransformation
Why is it important?
From speciation analysis, Trimethyl-arsine oxide (TMAO) resulted to be the predominant chemical form in the tissues of H. diversicolor exposed to all the spiked sediments. A possible explanation of its biosynthesis is that TMAO could be a chemical compound that increases resistance to As bioaccumulation.
