Impacts of Petroleum Fuels on Fertilization and Development of the Antarctic Sea Urchin Sterechinus neumayeri
Abstract Antarctic marine environments are at risk from petroleum fuel spills as shipping activities in the Southern Ocean increase. Knowledge of the sensitivity of Antarctic species to fuels under environmentally realistic exposure conditions is lacking. We determined the toxicity of 3 fuels, Speci...
