Organochlorine compounds in pine needles from Croatia.

Levels of seven organochlorine pesticides and 17 congeners of polychlorinated biphenyls (PCBs) were analysed in pine needles collected at eight sites along eastern Adriatic coast (Croatia). The concentration of organochlorine pesticides and PCBs ranged between 0 (below determination limit) and 7.44 ng g(-1) in 1-year-old needles and between 0 (below determination limit) and 15.57 ng g(-1) dry weight in 2-year-old needles. Organochlorine levels were compared with those found in urban and mountain areas.
