DDJC Tracy <br /> INITIAL RELEASE <br /> Likelihood of Health Effects From Ingestion of Stornrwater Lagoon Fish <br /> Nnncancer <br /> Using the estimated fish tissue concentration, ATSDR estimated exposure doses for a 70-kg adult <br /> consuming one 8-ounce fish meal per month, or approximately 0.0065 kg each day. Table C4 <br /> presents the resulting estimated exposure doses. As the table indicates, the estimated doses are <br /> less than the respective MRLs or RfDs (see Table C-4). Based on this finding, noncancer health <br /> effects are not expected to be associated with past consumption of fish caught from the <br /> stormwater lagoon. <br /> ancer <br /> Many of the compounds detected in the lagoon sediment are classified as probable human <br /> carcinogens by EPA. Therefore, ATSDR estimated excess lifetime cancer cases associated with <br /> consumption of lagoon fish and summarized the estimates in Table C-4. Based on these estimates, <br /> it appears that lagoon fish probably did not accumulate contaminants, if any, to levels that would <br /> contribute to excess cancer. ATSDR estimated that approximately one additional case of cancer <br /> might be expected over lifetime if 10,000 people ate fish from the lagoon for 30 years (based on <br /> estimated PCBs fish tissue concentrations). Because the lagoon was infrequently used for fishing, <br /> it seems unlikely that cancer will occur in the small population of former lagoon anglers from <br /> exposure to contaminants in lagoon fish. Therefore, ATSDR concludes that ingestion of fish from <br /> the lagoon in the past is not expected to result in an increased likelihood of developing cancer. <br /> Sources: <br /> ATSDR. 1997.
