Have We Been Focusing on the Wrong Ocean Pollutants? This Study Maps What We’ve Been Missing

by Mariana Mastache-Maldonado 13 May 202613 May 2026

A global analysis of more than 2,300 seawater samples found that largely unmonitored industrial compounds are widespread across oceans and may be changing crucial biological and carbon cycling processes.
