the case for a cause-effect linkage between environmental contamination and development in eggs of the common snapping turtle (chelydra s.serpentina) from ontario, canada.concentrations of polychlorinated biphenyls (pcbs), dibenzo-p-dioxins, and dibenzofurans, organochlorine pesticides, and their metabolites were measured in eggs of the common snapping turtle (chelydra s.serpentina) collected from four wetlands on the shorelines of lakes ontario, and erie, and one control location in central ontario, canada. snapping turtle eggs from these sites were also artificially incubated to determine hatching success, and incidence of deformities in embryo and hatchling tu ...19911908525
temporal and geographic variation of organochlorine residues in eggs of the common snapping turtle (chelydra serpentina serpentina) (1981-1991) and comparisons to trends in the herring gull (larus argentatus) in the great lakes basin in ontario, canada.common snapping turtle (chelydra serpentina serpentina) eggs from five sites within the great lakes basin, and from a reference site in north-central ontario were collected during 1981-1991 and analyzed for four organochlorine pesticides, polychlorinated biphenyls (pcbs) including six non-ortho pcbs, polychlorinated dibenzodioxins (pcdds), and polychlorinated dibenzofurans (pcdfs). the pattern of geographic variation was consistent over time in eggs with cootes paradise/ hamilton harbour and lyn ...19968975824
organochlorine pesticides, pcbs, dibenzodioxin, and furan concentrations in common snapping turtle eggs (chelydra serpentina serpentina) in akwesasne, mohawk territory, ontario, canada.subsamples of eight clutches of common snapping turtle eggs (chelydra serpentina serpentina) were collected from four sites from the territory of the mohawk nation, akwesasne, on the shore of the st. lawrence river. egg contents were analyzed for organochlorine pesticides, polychlorinated biphenyls (pcbs), dibenzodioxins, and furans. the sites were 2 to 13 km downstream from pcb-contaminated landfill sites. maximum concentrations of total pcbs in snapping turtle clutches were extremely high, and ...200111443374
