Plastic Risk Peaks When Fish Gather to Spawn
A global analysis argues that reproductive timing exposes hazards hidden by annual averages.
Summary
A global analysis argues that reproductive timing exposes hazards hidden by annual averages.
Researchers combined 6,327 seawater observations, 3,959 fish-burden samples, pollutant records, and reproductive data for 992 species across 65 large marine ecosystems. They estimate that 7.8 percent of critical spawning grounds exceeded ecological safety thresholds, while mean concentrations in the Baltic Sea and Gulf of Thailand were more than 7.8 times the global average. The study maps modeled ecological risk and co-exposure; it does not establish a uniform causal effect for every fish population.
