Chemical contamination along the Mediterranean French coast using Posidonia oceanica (L.) Delile above-ground tissues: a multiple trace element study

▸ P. oceanica is a sensitive bioindicator for the nineteen trace elements studied. ▸ Most elements were preferentially accumulated in photosynthetic parts of leaves. ▸ DRC ICP-MS allows us to measure the background level of all trace elements. ▸ The spatial variations can be related with anthropogenic activities. ▸ The third intermediate leaf can be used alone in chemical biomonitoring.
