Polyhalogenated compounds (Halogenated natural products and POPs) in sardine (Sardinops sagax) from the South Atlantic and Indian Oceans
Halogenated natural products (HNPs) and persistent organic pollutants (POPs) were quantified in South African sardines (Sardinops sagax) from one site in the South Atlantic Ocean and one in the Indian Ocean. At both sites, HNPs [2,3,3′,4,4′,5,5′-heptachloro-1′-methyl-1,2′-bipyrrole (Q1), mixed halog...
