توزع الفحوم الهيدروجينية الأليفاتية (AHs) في الرسوبيات الشاطئية البحرية لمصب نهر الكبير الجنوبي
Abstract
جمعت عينات رسوبية شاطئية من تسعة مواقع في منطقة مصب نهر الكبير الجنوبي خلال الفترة الزمنية الممتدة من 5/7/2004 ولغاية 20/6/2005 ، وجرى استخلاصها ودراستها نوعياً وكميا باستخدام تقانة الكروموتوغرافيا الغازية مع كاشف تشرد اللهب GC-FID من أجل تحديد الفحوم الهيدروجينية الأليفاتية (AHs).تراوحت تراكيز الـ (AHs) في الرسوبيات المدروسة مابين nd - 1793.7 ng/g (dry wt. ). سجلت أعلى تراكيز الـ (AHs) في الموقعين L/S9 و L/S8 على يمين المصب من الجانب السوري بالمقارنة مع التراكيز المسجلة في الموقعين L/S6 و L/S7 على يسار المصب من الجانب اللبناني .لحظ توزع لـ n-الألكانات ذات السلاسل الطويلة (n-C22 to n-C34) بكميات معتبرة في جميع المواقع .كما وجد توزع لـ n- الألكانات ذات السلاسل القصيرة (n-C12 to n-C21) في جميع العينات. لحظ أيضاً أن تراكيز (AHCs) كانت متقاربة مع التراكيز التي توجد في مناطق أخرى على الشاطئ الشرقي للمتوسط.
Samples of shore marine sediments from nine sites of estuarine- Alkabeer Aljnouby River were collected during the period (5/7/2004-20/6/2005). The samples were extracted to determine their quntitively and qualitatively content of Aliphatic (AHs) using GC-FID technique. The concentration of (AHs) ranged between nd - 1793.7 ng/g (dry wt.). The highest concentrations of (AHs) were reported in L/S9 and L/S8 on the right side of river estuarine (Syrian sector) in comparison with L/S6 and L/S7 on the left of river estuarine (Lebanon sector). The distribution of n-alkans showed significant quantities of long chain n-alkanes (n-C22 to n-C34) in all stations. In addition, short chain n-alkanes (n-C12 to n-C21) was present in all samples. In general, the concentration of (AHs) was similar to that found in other regions on the east coast of the Mediterranean.
