The Chemistry and Bioaccumulation of Copper and Other Heavy Metals by Phytoplankton in the Water Column of San Diego Harbor and their Relationship to Ecological Assessment and Water Quality( )

1 edition published in 1998 in English and held by 0 WorldCat member libraries worldwide

My long term goal is to determine the ecological importance of specific toxic metals (copper and zinc) in harbors, through an understanding of their chemistry and biological effects at the base of marine food chains. The major focus is on obtaining quantitative answers to research questions in this area, to establish what concentrations of these elements are acceptable when they are derived from anthropogenic sources. The specific objective is to determine the relationship between heavy metal chemistry and the accumulation of these metals in living cells. Such accumulation influences the toxicity of these metals to small grazers, which are the basis of EPA regulatory criteria and toxicity testing which EPA requires of many navy facilities
The Relationship Between Copper Speciation and Toxicity for Larvae of the Blue Mussel Mytilus edulis: Regulatory Implications and Determination of Water Effect Ratios( )

1 edition published in 2005 in English and held by 0 WorldCat member libraries worldwide

Copper toxicity to larvae of the blue mussel Mytilus edulis was quantified in chemically defined media to determine the relationship between concentrations of the free aquo Cu2+ ion and toxicity. The objective was to generate robust relationships to predict the effects of water chemistry on the toxic effects of copper and assess their ecological and regulatory implications. We found a robust relationship exists, suggesting that this species, a key organism in the regulatory enforcement community, is affected primarily by free Cu ions. This validates current assumptions behind the adoption of site-specific criteria derived from testing. However, the concentrations of free Cu ions required to observe chronic toxic effects (10-9M) are much higher than found in most harbors. Titration data in the literature suggest that dissolved concentrations of Cu in US harbors would have to be much higher before the survival of this organism was threatened. This is significant because an exhaustive study of Cu toxicity to invertebrates carried out in the 1970s found that Mytilus larvae were among the most sensitive species. It seems likely that concerns about Cu toxicity to marine planktonic invertebrates may be overstated. Caution must be exercised when extending these conclusions to benthic organisms, to which more refractory forms of Cu are probably bioavailable
