Article Synopsis
- Marinas contribute to higher levels of copper (Cu) in marine waters, mainly due to antifouling paints used on boat hulls.
- Washington State is developing legislation to regulate the release of Cu from these paints to protect marine environments.
- A study conducted in Puget Sound found that enclosed marinas showed significantly higher Cu concentrations than open ones, providing essential data for assessing the impact of future regulations.
Bay mussels (Mytilus trossulus) were transplanted to 18 locations representing a range of potential exposures throughout Puget Sound, WA. Tissues were analyzed for over 200 organic contaminants. Results indicated the widespread exposure of marine organisms to trace levels of organic contaminants including the synthetic opioid oxycodone, present at three urban sites, and the chemotherapy drug melphalan, present at nine locations, at levels that may be of biological concern.

- The study assessed how Pacific herring embryos accumulate polycyclic aromatic hydrocarbons (PAHs) in locations affected by a partially completed removal of creosote-treated pilings (CTPs).
- Embryos near undisturbed CTPs had higher levels of PAHs and increased expression of the cyp1a gene compared to those from cleaner reference areas.
- After CTP removal, embryos near debris showed PAH levels 90 times higher than reference areas, highlighting the risks of incomplete CTP removal for vulnerable fish populations.
