Persistent organic pollutants (POPs) which include chlorinated pesticides and petroleum hydrocarbons were determined in water samples collected from Damietta Harbour during 2005. Concentration of total pesticides ranged from 0.02 to 0.07 ng/L and from 1.09 to 201.82 ng/L during winter and summer seasons, respectively. The increasing order of total pesticides was: THCHs < TC < total DDTs with concentrations ranged from 0.004-3.20 ng/L, 0.001-3.93 ng/L and 0.002-194.68 ng/L, respectively in the area of study. The average concentrations of total petroleum hydrocarbons were below the admissible environmental levels. They ranged from 2.17-72.89 µg/L and from 5.67-87.56 µg/L during January and July 2005, respectively. However, concentrations of PAHs were... |
