Abstract AR
لقد تم دراسة التغير في تراكيز العناصر النزرة (Pb, Zn, Ni, Cd) في المواد العالقة و كذالك الخصائص الفيزيائية للمياه (درجة الحرارة، الملوحة، الأكسجين الذائب و درجة الملوحة) في خمس مناطق ساحلية و منطقة واحدة مرجعية (المياه المفتوحة) على أساس فصيلي للعام 2005, لقد أظهرت نتائج الدراسة تغيرات معنوية في درجة الحرارة، الملوحة، الحموضة و الأكسجين المذاب للفصول المختلفة بينما لم تظهر أي تغيرات جوهرية بين الأماكن المختلفة.
التغير الزماني لتراكيز العناصر المختلفة كان جوهريا (P < 0.001) بينما التغير المكاني لتراكيز العناصر المختلفة لم يكن جوهريا (P = 0.84).
أعلى تركيز تم رصده خلال فصل الربيع 0.137 جزء في المليون لعنصر Zn و 0.003 جزء في المليون لعنصر Pb, أقل تركيز تم رصده خلال فصلي الخريف و الشتاء لعنصر Cd (0.001 جزء في المليون).
لقد أظهرت الدراسة تراكيز قليلة للعناصر (Cd, Zn, Pb) في جميع مناطق الدراسة ما عدا عنصر Ni فقد تم رصد تراكيز تراوحت ما بين 0.108-0.12 جزء في المليون.

Variations of heavy metals concentrations (Pb, Zn, Ni and Cd) in suspended matter as well as the physical properties (Temperature, salinity, dissolved oxygen and pH) at five coastal sites and one reference station (offshore) were measured on seasonal base of the year 2005.
Seasonal variations of seawater temperature, salinity, pH and dissolved oxygen were significant different, meanwhile ; spatial variations among different stations were not significant.
Temporal variations of heavy metal concentrations were significantly different (P < 0.001) ; the highest concentrations were detected in spring 0.003 and 0.137 ppm for Pb and Zn respectively.
Very low concentrations of Cd (not exceed 0.001 ppm) were detected in autumn and winter.
Very low concentrations of Pb, Zn and Cd metals were detected in all sampling stations except Ni the concentrations were ranged between 0.12 And 0.108 ppm ; however, variations among different sampling sites were not significant (p = 0.84)
