Recent Advisory News

  • Coast guard: Cocos Island fish have high PCB levels. GUAM - The U.S. Coast Guard is requesting a reduction of the Cocos Lagoon fish advisory area based on recent PCB testing results from the area which show no detection in the Lagoon. In addition, fish tissue data indicated that PCB concentrations were higher in the near shore area. An environmental protection specialist with the U.S. Coast Guard suggested that people should continue to avoid the area of concern.

  • Utah fish found to have higher levels of mercury. UTAH - Results from a two-year mercury study conducted by the Utah Division of Water Quality indicated that mercury concentrations were elevated at 14 additional sites. Approximately 11 percent of the samples exceeded the EPA guideline and the highest concentrations were found in splake trout in the north arm of Emery County's Joes Valley Reservoir and in Upper Enterprise Reservoir rainbow trout in Washington County. State officials are still evaluating whether the current fish advisories need to be revised.

  • Fish in mother's diet benefits child, study finds. DISTRICT OF COLUMBIA - A recent British study showed that children of women who consume more fish during pregnancy have higher verbal ability and fewer behavioral problems. This raised questions regarding whether benefits associated with fish consumption outweigh the adverse effects associated with consumption of contaminated fish. EPA's Office of Water indicated that the current fish advisory will remain unchanged until further evaluation is conducted and study results could be replicated.

  • Waiting for the DDT tide to turn: Federal study shows that fish caught off L.A. County still contain the world's highest levels of the pesticide 35 years after it was banned. CALIFORNIA - Data released from a recent federal survey shows that DDT concentration is still highly elevated in many fish from Los Angeles County. A health advisory was issued by state officials in 1991 but surveys have indicated that highly contaminated white croakers were still found in some Asian markets in Los Angeles and Orange counties in 2004 and 2005. Study results indicated that DDT levels may be decreasing but additional data is needed to confirm the trend.

  • Residual levels of DDTs and PAHs in freshwater and marine fish from Hong Kong markets and their health risk assessment. Muscle tissue total DDT and PAH levels in freshwater and marine fish collected from Hong Kong markets were evaluated. Results indicated that PAH levels were relatively low and do not pose a concern for human health. DDT levels however were elevated when compared to the USEPA screening value. In brief, 45% and 70% of the freshwater and marine fish samples exceeded the screening value, respectively.

  • Metal levels in flathead sole (Hippoglossoides elassodon) and great sculpin (Myoxocephalus polyacanthocephalus) from Adak Island, Alaska: potential risk to predators and fishermen. This paper summarizes heavy metal concentrations observed in sculpin and sole collected from Adak Island in the Aleutian Islands, Alaska. The authors concluded that arsenic, lead, and mercury levels from these samples may pose a health risk to human consumers.

  • Fetal methylmercury exposure as measured by cord blood mercury concentrations in a mother-infant cohort in Hong Kong. Mercury levels in maternal blood, cord blood, and hair samples from newborn infants in Hong Kong and correlation with fish consumption and maternal age were evaluated in this study. Maternal fish consumption and maternal age were found to be positively correlated with cord blood mercury levels. Approximately 78% of the cord blood samples were above 29 nmol/L. Marine fish consumption was found to have a stronger positive correlation with mercury concentration than freshwater fish consumption.

  • Polychlorinated biphenyls and their hydroxylated metabolites (OH-PCBs) in pregnant women from eastern Slovakia. PCBs and specific polychlorobiphenylol (OH-PCB) metabolites in maternal sera from women delivering in eastern Slovakia were evaluated. Results indicated that body burdens of PCBs and OH-PCB metabolites may result in potential adverse health effects to mothers residing in eastern Slovakia.
