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.
