摘要: Semivolatile persistent organic pollutants (POP) are bioaccumulative and toxic contaminants. Their global distribution depends on source distribution, atmospheric transport, degradation, the exchange with ocean land surfaces. Forests crucial terrestrial reservoirs due to commonly envisaged high capacity of their surface soils store immobilize airborne contaminants bound soil matter. Our results show that POPs can be unexpectedly mobile in a tropical rainforest fast litter turnover (leading rapid POP transfer subsoil) leaching rates exceeding degradation especially for more hydrophobic congeners. Co-transport association fine particulate dissolved matter appears as relevant driver this PCB export. A markedly different pattern is displayed comparison colder environments lower overall storage capacity. These findings biogeochemistry weathering influence fate. Because forests represent 60% productivity, highlighted dynamics might have an implication general these
