“…and its relationship to an entropy gain that dominated the transfer process from water to algae, and found it to be similar to what was observed in fish. A slight increase in the BCF for pentachlorophenol (32) was reported in zebra mussel when temperatures were higher; however, BCF changes for dieldrin (22), lindane (30), and pentachlorophenol (32) were insignificant in other mussels (Boryslawskyj et al 1988;Ernst 1979;Fisher et al 1999). Therefore, the temperature effect on BCF appears to be less important for bivalva.…”

“…Furthermore, in cold weather, either FA unsaturation or content of phosphatidyl-ethanolamines (PE), -inositols (PI), and -serines (PS) increased in PL; these factors are lined with membrane fluidity (Lin et al 2003;Pirini et al 2000). Increased FA unsaturation was induced when a freshwater mussel was acclimatized at a lower temperature (Boryslawskyj et al 1988).…”

The ecotoxicological assessment of pesticide effects in the aquatic environment should normally be based on a deep knowledge of not only the concentration of pesticides and metabolites found but also on the influence of key abiotic and biotic processes that effect rates of dissipation. Although the bioconcentration and bioaccumulation potentials of pesticides in aquatic organisms are conveniently estimated from their hydrophobicity (represented by log K(ow), it is still indispensable to factor in the effects of key abiotic and biotic processes on such pesticides to gain a more precise understanding of how they may have in the natural environment. Relying only on pesticide hydrophobicity may produce an erroneous environmental impact assessment. Several factors affect rates of pesticide dissipation and accumulation in the aquatic environment. Such factors include the amount and type of sediment present in the water and type of diet available to water-dwelling organisms. The particular physiological behavior profiles of aquatic organisms in water, such as capacity for uptake, metabolism, and elimination, are also compelling factors, as is the chemistry of the water. When evaluating pesticide uptake and bioconcentration processes, it is important to know the amount and nature of bottom sediments present and the propensity that the stuffed aquatic organisms have to absorb and process xenobiotics. Extremely hydrophobic pesticides such as the organochlorines and pyrethroids are susceptible to adsorb strongly to dissolved organic matter associated with bottom sediment. Such absorption reduces the bioavailable fraction of pesticide dissolved in the water column and reduces the probable ecotoxicological impact on aquatic organisms living the water. In contrast, sediment dweller may suffer from higher levels of direct exposure to a pesticide, unless it is rapidly degraded in sediment. Metabolism is important to bioconcentration and bioaccumulation processes, as is detoxification and bioactivation. Hydrophobic pesticides that are expected to be highly stored in tissues would not be bioconcentrated if susceptible to biotic transformation by aquatic organisms to more rapidly metabolized to hydrophilic entities are generally less toxic. By analogy, pesticides that are metabolized to similar entities by aquatic species surely are les ecotoxicologically significant. One feature of fish and other aquatic species that makes them more relevant as targets of environmental studies and of regulation is that they may not only become contaminated by pesticides or other chemicals, but that they constitute and important part of the human diet. In this chapter, we provide an overview of the enzymes that are capable of metabolizing or otherwise assisting in the removal of xenobiotics from aquatic species. Many studies have been performed on the enzymes that are responsible for metabolizing xenobiotics. In addition to the use of conventional biochemical methods, such studies on enzymes are increasingly being conducted using immunochemical met...

“…Consequently, mussels have been used in many contaminant monitoring programs (Bedford and Zabik 1973, Adams et al 1981, Schmitt et al 1987, Boryslawskyj et al 1988). Our objectives were (1) to obtain baseline information on the concentrations of cadmium, copper, mercury, and zinc in threeridge mussels Amblema plicata plicata from the upper Mississippi River; (2) to compare metal concentrations in mussels from an area where metal abundances have been greatly increased 'Present Address: U.S.…”

Concentrations of mercury and zinc in the threeridge mussel Amblema plicata plicata, sampled in 1987 from Pools 3 and 10 in the upper Mississippi River, were comparable to concentrations in mussels from moderately contaminated systems, while copper concentrations were similar to concentrations in mussels from more polluted waters.Cadmium concentrations in mussels were significantly less at a lightly contaminated site (Pool 10, range 0.53 to 0.92 pg/g dry weight) than at a site where metal abundances were strongly influenced by industrial and domestic inputs (Pool 3, range 0.80 to 1.25 pg/g dry weight).Yet, cadmium concentrations in Pool 3 were an order of magnitude less than values reported for mussels from more metal-polluted systems.In contrast, concentrations of copper, mercury, and zinc did not differ between sites. Cadmium and zinc concentrations generally increased with size of the mussel, copper concentrations decreasedwith size, and mercury concentrations were unrelated to size.

The Braer tanker wreck demonstrated the danger ofpetroleum spills to salmon farms. The water soluble@action (WSF) of crude petroleum oils is quite direrent from the parent oils. It is rich in methyl-and alkyl-substituted monoaromatic and lower molecular weight polyaromatic hydrocarbons, guaranteeing strong petroleum flavor. Both n-alkanes above C, and more complex hydrocarbons above the methylnaphthalenes are virtually absent. The WSF in salmon intercellular fluids is rapidly depurated but a portion dissolves into the adipocyte cells in the salmon muscle and is retained much longer. The distribution of adipocytes along the myosepta of white muscle and in the belly flaps has been defined by histochemistry and their isolation by collagenase, centrifigation, andflotation is &scribed in dark muscle small fat droplets are instead found among and within the cells of musclejbers.
