Abstract

Annaba gulf is a coastal area (southwestern Mediterranean Sea) that receives large diffuse inputs from Fertial plant, Seybouse wadi and Boujemaâ wadi, which are influenced by anthropogenic activities. Wastewaters and surface waters and sediments from these sites were analyzed for Polycyclic Aromatic Hydrocarbons (16 PAHs) by using gas chromatography system operating with the flame ionizing detector (FID). Total PAHs ranged from 0.033 to 0.503 µg L^–1 in water, and from 32.44 to 509.58 µg kg^–1dw in sediments. In order to identify pollution emission sources of PAHs, three source identification techniques were used, including diagnostic ratios, Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA). The results show that the pollution originated mainly from pyrogenic inputs in water and sediments. Annaba Bay basin is contaminated mainly by heavy PAHs discards originated from domestic and industrial wastewaters and traffic emissions.

阿尔及利亚安纳巴湾盆地水和沉积物中多环芳烃的污染和来源识别

摘要

安纳巴海湾是一个沿海地区（西南地中海），受人为活动的影响，从肥力植物Seybouse wadi和Boujemaâwadi获得大量的分散输入。通过使用配有火焰离子化检测器（FID）的气相色谱系统对这些场所的废水，地表水和沉积物进行了多环芳烃（16 PAHs）分析。水中的多环芳烃含量范围从0.033至0.503 µg L ^–1，从32.44至509.58 µg kg ^–1沉积物中的dw。为了识别PAHs的污染排放源，使用了三种污染源识别技术，包括诊断率，主成分分析（PCA）和层次聚类分析（HCA）。结果表明，污染主要来自水和沉积物的热输入。安纳巴湾流域主要被生活和工业废水和交通排放中大量的多环芳烃所污染。
