Abstract
Anthropogenic contamination in the Antarctic near-shore marine environment is a challenge for environmental managers because of its isolation, high costs associated with monitoring and remediation activities, and the current lack of Antarctic-specific ecotoxicological data. The present study investigated the application of diffusive gradients in thin films (DGT) with a Chelex-100 binding resin for metal contaminant assessment in Antarctic marine conditions. Diffusion coefficients for cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb), and zinc (Zn), determined at 1 °C, ranged between 2.1 and 2.6×10-6 cm2 /s and were up to 32% lower than those derived by theoretical calculations. Competition of metals on the DGT binding resin was observed at subsaturation concentrations, reducing the effective capacity for metal uptake by approximately 60%. The lability of the dissolved (0.45 µm filterable) Cd, Cu, Pb, and Zn metal fraction to DGT was generally >90% and unaffected by the presence of the Antarctic marine microalga Phaeocystis antarctica. Both DGT and dissolved metal concentrations gave equivalent mixture toxicity predictions in independent action and concentration addition models to P. antarctica and Cryothecomonas armigera; that...Continue Reading
