WebApr 14, 2024 · Highlights Abstract Decabromodiphenyl-ether (BDE-209) is a persistent organic pollutant ubiquitously found in marine environments worldwide. Even though this emerging chemical contaminant is described as highly toxic, bioaccumulative and biomagnifiable, limited studies have addressed the ecotoxicological implications … Webocean acidification, the worldwide reduction in the pH of seawater as a consequence of the absorption of large amounts of carbon dioxide (CO2) by the oceans. Ocean acidification is largely the result of loading Earth’s atmosphere with large quantities of CO2, produced by vehicles and industrial and agricultural processes. Since the beginning of the Industrial …
