Toxic anthropogenic signature in Antarctic continental shelf and deep sea sediments
7 pages, 4 figures, 1 table Industrial activity generates harmful substances which can travel via aerial or water currents thousands of kilometers away from the place they were used impacting the local biota where they deposit. The presence of harmful anthropogenic substances in the Antarctic is par...
