摘要

Water quality standards for cobalt (Co) have yet to be developed for the European Union or the United States. The primary objective of the present study was to produce a data set comprising marine Co toxicity data that could be used by both the European Union and the United States to determine a predicted-no-effect concentration and ambient water quality criteria, respectively. Ten marine species, ranging from algae to fish, were subjected to chronic Co toxicity tests that were designed to meet international water quality testing standards. Chronic 10% effect concentration values ranged from a low of 1.23 mu g dissolved Co/L for red algae (Champia parvula) to a high of 31 800 mu g dissolved Co/L for sheepshead minnow (Cyprinodon variegatus). The species sensitivity ranking for chronic marine Co exposure was as follows (from most to least sensitive): C. parvula Neanthes arenaceodentata (polychaete) Americamysis bahia (mysid shrimp) Skeletonema costatum (marine diatom) Dendraster excentricus (sand dollar) Mytilus galloprovincialis (mussel) Strongylocentrotus purpuratus (purple sea urchin) Crassostrea gigas (oyster) Dunaliella tertiolecta (marine flagellate) C. variegatus. Chronic test results indicated that invertebrate and plant species were substantially more sensitive to Co exposure than fish. The chronic toxicity data were used to calculate a species sensitivity distribution, from which a hazardous concentration 5th percentile of 7.09 mu g dissolved Co/L (95% CI 0.025-47.3 mu g Co/L) was derived.
