Alternative Title
تقدير الملوثات العضوية ذات الثباتية فى مياه ميناء دمياط الجديد بمصر
Abstract
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 below the detection limit in the present study.
تم تقدير الملوثات العضوية الأكثر ثباتية والتى تشمل المبيدات العضوية والمواد الهيدروكربونية البترولية في مياه ميناء دمياط الجديدة المصرى خلال موسمى شتاء وصيف 2005م. تراوح تركيز المبيدات الكلية مابين 0.016-0.068نانوجرام/لتر، 1.09 – 201.82 نانوجرام/لتر خلال يناير، يوليه 2005م على الترتيب. سجلت معدل المبيدات لمركبات الهكساكلوروسيكلوهكسان الكلية > السيكلودايين الكلية > الدىدىتى الكلية بمنطقة الدراسة. بلغ تركيز ات تلك المركبات مابين 0.004-3.2 & 0.001- 3.94 & 0.002-194.68 نانوجرام/لتر على الترتيب. سجل المحتوى الكلى للمواد البترولية الذائبة مابين 2.17-72.89& 87.56-5.67 ميكروجرام/لتر خلال شهر يناير، ويوليه 2005م على الترتيب. كانت معدلات المواد البترولية متعددة الأنوية أقل من الحد الممكن قياسه بإستخدام جهاز كروماتوجرافيا الغاز. أوضحت الدراسة أن منطقة ميناء دمياط الجديدة تعتبر منطقة شبه مغلقه تتأثر بحركة الشحن والتفريغ داخل الميناء بالإضافة إلى الصرف الزراعى والصحى الناتج من محافظة دمياط.
