Heavy metals in the aquatic environment of the Southern Adriatic Sea, Italy Macroalgae, sediments and benthic species

摘要

Samples of sea urchins (Paracentrotus lividus), holothurians (Holothuria polii), green algae (Ulva lactuca, Codium vermilara and Enteromorpha prolifera) and sediments were collected from different coastal zones of the South Adriatic Sea (Italy). The occurrence of metals In macroalgae is poor especially if compared with the reported in other coastal areas affected by human activities, with the exception of Fe That showed high mean values (405 μg g~-1 dry wt.). Likewise, relationship between metal concentrations in holothurians and sediments Were found, demonstrating that H. Polii could serve as bioindicator for Hg and Cu.
