“…Steric parameters such as molecular size and shape sometimes also become important factors in passive uptake (Barron 1990;Landrum and Fisher 1998). Shaw and Connell (1984) did not demonstrate a correlation between BCFs of polychlorinated biphenyl (PCB) compounds normalized to that of 2 ,3,4,4 ,5 -pentachlorobiphenyl, with their log K ow values, in mullet and the polychaete Capitella capitata.…”

“…It is important to consider a host of factors when generating bioaccumulation data, including exposure levels of a chemical in interstitial water, presence of sediment particles or detritus, dietary habits of each tested organism, etc. (Connell 1988;Landrum and Fisher 1998;Miyamoto et al 1990).

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...

“…Both the geologically young Great Lakes and the PontoCaspian regions have histories of climactic instability, dramatic basin and waterway changes, and more recently -heavy metal, pesticide, fertilizer, and run-off pollution. The round goby has particularly high pollution tolerance (Moskal'kova 1996;Landrum and Fisher 1998), which may aid its success in new and marginal habitats. In addition, results of ecological studies predict that invasion-prone communities have lower overall species diversities and offer greater niche opportunities (Elton 1958;Case 1990;Moulton and Pimm 1993;Shea and Chesson 2002).…”

Genetic variability and structure of nonindigenous vs native populations are compared for the Eurasian round goby Neogobius melanostomus and the tubenose goby Proterorhinus marmoratus, which both invaded Lake St. Clair of the North American Great Lakes about 1990. The round goby spread rapidly to all of the Great Lakes and the tubenose goby largely has been restricted to Lake St. Clair, with some recent range extension into western Lake Erie. Risk analyses may indicate whether genetic variability of colonizers is predictive of their relative invasive and establishment successes. The present investigation examined DNA sequence variation across the left domain of the mitochondrial DNA cytochrome b gene in round and tubenose gobies from Eurasian and Great Lakes locations. We also sequenced six additional Neogobius species (including the monkey N. fluviatilis, racer N. gymnotrachelus, and bighead N. kessleri gobies that have been 'on the move' in Europe) and the knout goby Mesogobius batrachocephalus from the Black Sea in order to develop diagnostic genetic characters to identify them in case of future and/or undetected invasions and to delineate their phylogenetic relationships. Results show that a diverse number of haplotypes characterize round and tubenose goby populations from both North America and Eurasian sites, fitting a risk analysis prediction of high genetic variability in their successful introductions. Phylogenetic results indicate that the current genus Neogobius is paraphyletic and that the subgenus Apollonia thus should be elevated to the level of genus, containing Apollonia (N.) melanostomus (the round goby) and A. (N.) fluviatilis (the monkey goby). In addition, there appear to be two separate species of Proterorhinus marmoratus, a marine P. marmoratus Pallas 1814 in the Black Sea (matching the original type locality), and a 'cryptic' freshwater species in the Danube and Dnieper Rivers and probably other Eurasian freshwater habitats, as well as invasive in the Great Lakes. We suggest resurrecting the name P. semilunaris Heckel 1837 for the freshwater species (a taxon that was originally described from rivers draining into the Aegean Sea and the Danube River, but was later placed in synonymy with P. marmoratus).

“…The bioaccumulation is a measure of the degree of enrichment in bodily tissue. Again, a moderately toxic pharmaceutical present in the environment in minute concentrations (corresponding to a low PECvalue) can reach concentrations in fish tissue that are 1 000 -1 00 000 times higher if the pharmaceutical is bioaccumulative (occurs within a trophic level, and is the increase in concentration of a substance in an individuals' tissues due to uptake from food and sediments in an aquatic milieu) and/or if the substance and has a corresponding bioconcentration factor, BCF) (Suedel et al, 1994, andLandrum andFischer, 1999).…”
