Exposure of Corophium orientale to spiked sediments

What is it about?

In marine ecosystems, benthic organisms are really important because they are the first step in the transfer of contaminants from environment to biota. To this end, this study focused on biological assays with the amphipod Corophium orientale exposed to two different molecules of arsenic.

Why is it important?

Differences in matix composition could result in reducing or increasing the toxicity of arsenic compound. We evaluate the influence of this aspect in the different toxicity of three arsenic compounds. This work, together with others of our group, can contribute to a better knowledge of toxicity of these compounds measured with ecotoxicological assays.

This study can provide some useful data linked with chemical speciation of arsenic and exposure matrix, for improving the correct management of contaminated sediment.
