Embryotoxicity of Great Lakes Lake Trout Extracts to Developing Rainbow Trout.Entry ID: usgsbrdcerc_GreatLakeslaketrout
Abstract: Planar halogenated hydrocarbons (PHHs), such as polychlorinated
dibenzo-p-dioxins, dibenzofurans, and biphenyls are present in aquatic systems,
and are known to produce adverse effects in fish. This study investigated the
embryotoxicity of PHH mixtures through the nanoinjection of environmental
extracts into newly fertilized eggs from two strains of rainbow trout. Organic
extracts were obtained ... from whole adult lake trout collected from Lake Michigan
in 1988 and Lake Superior in 1994. The graded doses of the final extracts used
for injections were quantified as 2,3,7,8-tetrachlorodibenzo-p-dioxin toxic
equivalents (TEQs) based on the concentrations of dioxins, furans and
non-o-PCBs in each, and as equivalent amounts found in the eggs of the original
lake trout (eggEQ).
The objectives of the study were to extract and quantitate the PHHs present in
Lake Michigan lake trout tissue; determine the embryotoxic effects of this
extract toward rainbow trout; determine if an additive model of toxicity of
PHHs adquately describes the embryotoxic effects of this chemical mixture; and
estimate the hazard these chemicals may represent toward lake trout populations
in the Great Lakes.
