“…Also in 198911990, organochlorine pesticides were highest in eggs from the Cornwall area. Eggs collected from Akwesasne and from Long Sault (Figure I), near Dioxin andFuran Concentrations (1984'1989) Cornwall, upstream of Akwesasne, contained organochlorine pesticide concentrations that were two to three times higher than those from the other sites studied on the St. Lawrence River (Bonin et al 1995). The concentrations of pesticides in eggs from the Cornwall area were similar to those found in eggs sampled in 1984 at that general area by Struger et al (1994).…”

“…The most contaminated sample collected was a Lake Erie water snake from Pelee Island, Lake Erie in which the liver contained 0.46 "gig p,p'-DDE and 6.58 "gig Aroclor 1254: 1260. Maximum mercury concentration among all samples was 0.39 "gig which is actually lower than levels Lawrence River (Bonin et al 1995). To date, the concentrations of p,p'-DDE in the eastern spiny softshell eggs from Rondeau Provincial Park of Lake Erie are the highest ever found in any reptile egg (see Meyers-Shone and Walton, 1994).…”

Abstract. Bioaccumulation of environmental contaminants has been documented in amphibians and reptiles inhabiting the Great Lakes, 8t. Lawrence River and elsewhere. The effects of pollutants on the physiology and reproduction of amphibians and reptiles has also been reported but this research has largely been restricted to laboratory studies. Much less work has been conducted to quantifY the effects of toxic chemical exposures on these cryptic animals in the wild. In the Great Lakes basin and 8t. Lawrence River, this work has only been performed in detail since 1981 although some samples collected in 1974 indicated a high level of contamination. Results in the 1990s on aquatic salamanders, frogs and turtles indicate that adults and embryos are currently experiencing toxic effects and, in some species and locations, there are indications that population declines are influenced by environmental pollution exposure. In this review, we describe the existing literature on contaminant levels and effects in reptiles and amphibians of the 8t. Lawrence River and Great Lakes basin.

“…For many vertebrates, such as turtles, eggs can be useful indicators of contaminant exposure. Previous research (Bishop et al 1994;Bonin et al 1995) found that organochlorine concentrations in snapping turtle eggs reflect the spatial variation of these contaminants within the turtle's habitat. Diamondback terrapin (Malaclemys terrapin) eggs may also be useful in elucidating spatial contamination patterns and levels of organismal exposure due to their wide distribution throughout estuaries in the eastern seaboard and the gulf coast of the United States.…”

Spatial Variation in Polycyclic Aromatic Hydrocarbon Concentrations in Eggs of Diamondback Terrapins, Malaclemys terrapin, from the Patuxent River, Maryland

Aquatic organisms encounter a number of contaminants in their environments. Here, we report polycyclic aromatic hydrocarbon (PAH) concentrations detected in diamondback terrapin eggs collected from the Patuxent River, Maryland, one year after an oil spill. Data suggested a geographic difference in egg hydrocarbon concentrations. However, at one year after the oil spill, most PAH concentrations detected were low, were not correlated with the extent of shoreline oiling, and thus likely represent current background levels. Future research should investigate the route of egg PAH exposure and include studies of embryotoxicity.

The great blue heron (Ardea herodias) has been used as a bioindicator of the state of the St. Lawrence River (Québec, Canada) since 1996. At 5-year intervals, selected breeding colonies along the River and its estuary are visited to estimate reproductive success and determine levels of contamination. Brominated flame retardants are found in many ecosystems and are increasing in concentration in the Great Lakes, which is the source of much of the water for the St. Lawrence River. In 2001 and 2002, in addition to polychlorinated biphenyls (PCBs) and chlorinated pesticides, the levels of polybrominated diphenyl ethers (PBDEs), polychlorinated bornanes (toxaphene) congeners and non-ortho-substituted PCBs were measured for the first time in pools of great blue heron eggs. The PBDE levels in great blue heron eggs (70-1,377 ng/g wet wt) were comparable to those measured in herring gull (Larus argentatus) eggs from the Great Lakes. Toxaphene was detected in great blue heron eggs at levels comparable to those of other major chlorinated pesticides. Major toxaphene congeners were octachlorobornane P44 and the nonachlorobornane P50. Environ.
