POPs that are
released into the environment, being volatile in warm climates, can
be transported over large distances via atmospheric circulation,
before being deposited in colder environments (Muir and de Wit,
2010). Most POPs are hydrophobic and persistent in the environment;
as a result, they tend to bioaccumulate in organisms (Newman,
2010). POPs biomagnify in food webs, so reach highest concentrations
in top predators (Fisk et al., 2001; Gabrielsen, 2007). Since POPs
