Pollution Studies with Marine Plankton: Part II. Heavy Metals

Davies The Laboratory, Marine Biological Association, Plymouth, England Available online 15 May 2008 Choose an option to locate/access this article: Check if you have access through your login credentials or your institution Check access Get rights and content This chapter reviews the present understanding of the effects of heavy metals upon marine plankton and highlights the fact that although, at present, the data obtained from laboratory experiments cannot usually be used to assess the degree to which natural populations are at risk due to metal pollution, it might now be possible to begin to rectify the situation. Comparative sensitivity of Scenedesmus acutus and Chlorella pyrenoidosa as sentinel organisms for aquatic ecotoxicity assessment: Studies on a highly polluted urban river - Olguín - 2000 - Environmental Toxicology. The effects of spatial and temporal differences on the water quality of the urban contaminated Reconquista River (Argentina) were evaluated by means of bioassays based on the growth of two algal populations (Chlorella pyrenoidosa and Scenedesmus acutus).

The effects produced by the addition of cadmium and/or nutrient salts to the samples were also assayed. Noticeable differences in algal biomass were detected among samples from different sites, the highest values corresponding to the most polluted zones. The toxic effect of cadmium was more pronounced in S. acutus than in C. pyrenoidosa, particularly in the least polluted waters.

The addition of nutrient salts to the culture medium attenuated heavy metal toxicity, mainly to C. pyrenoidosa, and also revealed nutrient limitation to algal growth in certain sites and dates. Site classifications based both on algal bioassays and on physical and chemical variables showed good agreement. ©2000 John Wiley & Sons, Inc.
