Summary


Persistent organic pollutants (POPs) are chemical substances that persist in
the environment, accumulate in the food web, and pose a risk of adverse
effects in humans and wildlife (1). Rachel Carson first identified the
potentially devastating effect of POPs on wildlife in the early 1960s (2).
In the late 1960s, polychlorinated biphenyls (PCBs) were detected in high
concentrations in wildlife in Sweden (3). After PCB use and manufacture were
banned in 1979 (US), 1981 (UK), and 1987 (EU), levels started to decline
slowly in all biota around the world (4-6). In 2004, the Stockholm
Convention committed more than 90 signatory countries to phasing out or
eliminating large stocks or other sources of POPs, including PCBs (1). Yet,
PCBs continue to threaten the survival of marine predators. Concerted
efforts are thus still needed to mitigate PCB pollution.
