Chlorinated Biphenyls and p, p'-DDE in Mediterranean Surface Waters

摘要

Individual chlorobiphenyls (CBs) and p, p'-DDE were determined in solution and suspension in surface transects of the open Mediter- ranean Sea in 1987. Large volumes of sea water (1400-1700 dm~3) were analyzed. Concentrations of CBs were low in solution (<5 pg/dm~30 and in sus- Pension (<60 pg/dm~3). Values for their sum (∑CB) were 1.7-43.9 And 190-615 pg/dm~3, respectively. Compositions of the CB mix- Tures in solution as well as those in suspension were very similar In the various transects, but considerable differences were present Between solution and suspension in each transect.
