• 1 Read our final study report The Grand Lake Watershed Mercury Study was designed as a community-based participatory research project to address community concerns in northeastern Oklahoma about mercury exposure and mercury levels in fish. Over 1500 fish collected throughout the watershed were tested for mercury during the study and over 150 local residents participated by completing questionnaires about their fish consumption and getting their hair tested for mercury exposure.
  • 2 Our new research paper published in Environmental Research

    Our paper in Environmental Research shows that 95% of participants in our study were below EPA's guideline for mercury exposure, based on hair mercury levels. Older participants were more likely to have higher mercury, and men had higher exposure than women.

  • 3 FDA and EPA Issue Draft Updated Advice for Fish Consumption The U.S. FDA and EPA recently announced an update to their fish consumption guidelines. They recommend that pregnant and breastfeeding women, women who might become pregnant, and young children should eat more fish low in mercury in order to gain important developmental and health benefits. View more information about fish consumption and the update here.
