Copper threatens marine ecosystems.

The article offers science news briefs on the ecological risks of copper-based antifouling paints in marine environments. It explains how these paints, widely used after the global ban on tributyltin, release copper compounds that impair fish, and bivalves, accumulate in sediments, and worsen under ocean acidification. It emphasizes that current regulations are outdated and urges countries, including the U.S., to adopt stricter standards while supporting copper-free antifouling innovations.
