A high prevalence of germinomas has been observed in certain populations of Mya arenaria from eastern Maine. The etiology of these tumors is unknown. We are investigating the hypothesis that exposure to environmental contaminants, such as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) contributes to

Numerous reports have raised the level of national concern that chemicals found in the environment may have adverse effects on the health of humans and wildlife. Environmental exposure to pollutants, such as dioxin, has been implicated in gonadal tumor formation in Maine softshell clams (Mya
