Exploring global oceanic persistence and ecological effects of legacy persistent organic pollutants across five decades.

ABSTRACT: Global monitoring of persistent organic pollutants (POPs) has intensified following regulatory efforts aimed at reducing their release. In this context, we compiled over 10,000 POP measurements, reported from 1980 to 2023, to assess the effectiveness of these legislative measures in the global marine environments. While a general decreasing trend in legacy POP concentrations is evident across various maritime regions, highlighting the success of source control measures, the Arctic Ocean and its marginal seas have experienced a rise in POP levels. This increase suggests the northward migration of pollutants via ocean currents from mid-latitude regions to polar areas. Despite global efforts to reduce emissions, the continued transport and accumulation of pollutants to the Arctic regions may
