Abstract

To assess the heavy metals concentration in the coastal sediments of the southern Kuwait coast, Fe, Mn, Cu, Pb, Ni, Co, Cd and Cr were measured by inductively coupled plasma mass spectroscopy. Whereas, the south of Kuwait coast is characterized by the presence of tourist resorts, and commercial and oil exports harbors. Moreover, environmental indicators were used to help in evaluating the degree and the intensity of pollutants in these sediments. Geoaccumulation index (Igeo) revealed that the sediments of hard all Hamara and Al-Khiran coasts are moderately polluted by Cu, while Ras Al-Zour and Ras Al-Jula'ia coasts are moderately polluted by Cd. Moreover, the enrichment factor (EF) indicated that the sediments of Hadd Al-Hamara coast are severely enriched with Ni, Cr and Pb, while the Al-Khiran coast is moderate severely enriched with the same metals. Ras Al-Zour and Ras Al-Jula'ia coasts are severely enriched with Ni and very severely enriched with Pb. Simultaneously, all studied sites are extremely severely enriched with Cu and Cd. These results were confirmed by the results of the contamination factor (CF) and the soil pollution index (SPI) indicated that Hadd Al-Hamara and Al-Khiran coasts are highly contaminated with Cu and Cd, while Ras Al-Zour and Ras Al-Jula'ia coasts are highly contaminated with Cd. Generally, the pollution load index showed that the sediments of all studied sites are no heavy metal pollution (PLI < 1). Pollutants might be originated from commercial wastes and construction activities.

科威特南部沿海沉积物重金属污染现状及污染评价
为了评估科威特南部海岸沉积物中重金属的浓度,采用电感耦合等离子体质谱法测定了Fe、Mn、Cu、Pb、Ni、Co、Cd和Cr。然而,科威特南部海岸的特点是旅游胜地、商业和石油出口港口的存在。此外,环境指标有助于评价这些沉积物中污染物的程度和强度。地质堆积指数(Igeo)显示,hard all Hamara和Al-Khiran海岸的沉积物受Cu的中度污染,而Ras Al-Zour和Ras Al-Jula'ia海岸的沉积物受Cd的中度污染。富集因子(EF)表明,Hadd Al-Hamara海岸的沉积物严重富集Ni、Cr和Pb,而Al-Khiran海岸的沉积物则是中度富集。Ras Al-Zour和Ras Al-Jula'ia海岸严重富集镍和非常富集铅。同时,所有研究地点的Cu和Cd富集程度都非常严重。污染因子(CF)和土壤污染指数(SPI)结果证实了这一结果,表明Hadd Al-Hamara和Al-Khiran海岸是Cu和Cd的高污染地区,而Ras Al-Zour和Ras Al-Jula'ia海岸是Cd的高污染地区。污染负荷指数表明,各研究点沉积物均不存在重金属污染(PLI < 1),污染物可能来源于商业废弃物和建筑活动。
