An Assessment of Sediment Toxicity in the River Tyne Estuary, UK by Means of Bioassays

摘要

This paper describes an evaluation of the toxicity of contaminate sediments obtained in June 1992 from six intertidal stations on a 25 km stretch of the Indus- trialised River Tyne Estuary in northeast England. The bioassays for toxicity included the amphipod Corophium spp. and the polychaete Arenicola marina whole sediment tests, as well as tests on elutriates with the copepods Tisbe bat- tagliai and Acartia tonsa, the embryo of the oyster Crassostrea gigas, the light- emitting bacterium Photobacterium phosphoreum and the unicellular algae Tetraselmis suecica and Thalassiosira pseudonana.
