Advice on fishing for safe seafood to eat

The only Duwamish seafood safe to eat is salmon. In the Duwamish River, the seafood that spend their entire lives in the river (perch, sole, flounder, crab, mussels and clams) are unsafe to eat. They have high levels of toxic chemicals (such as PCBs) that you cannot see. Toxic chemicals can harm unborn babies, infants and young children the most – impacting their memory, attention, motor skills and language development.

South Park Community Center Open Space Design Plan: Rapid Health Impact Assessment (HIA) Findings & Recommendations

Environmental Health Services (EHS) staff conducted a rapid Health Impact Assessment (HIA) to inform Seattle Parks & Recreation’s design and planning decisions that could improve the health and well-being of South Park children and other residents, particularly in light of the existing inequities the community already faces. Our rapid HIA process included a desk-based review of published literature, best practices and recent community recommendations; and consultations with technical subject matter experts and community representatives. We focused on these health determinants: air pollution, environmental noise, crime and safety, social and mental health, physical activity, heat, and pedestrian safety.
