Abstract

Abstract The ecological risk resulting from the accumulation of some heavy metals in the sediments of Iskenderun Bay was assessed using the following measures: enrichment and contamination factor, pollution load index (PLI), and potential ecological risk index (RI). The concentrations of the studied heavy metals were in the following order: Fe > Ni > Mn > Cr > Zn > Cu > As > Pb > Cd > Hg. Ni and As had the highest EF values. This situation is most likely due to the presence of iron, pesticide, and fertilizer plants in the region. According to the United States Environmental Protection Agency, Ni, As, Mn, and Cr may have harmful effects on faunal communities in sediments. According to the RI, Site 4 was more contaminated and toxic than the other seven study sites, with “moderate” ecological risk. Pearson’s correlation coefficient was determined by multivariate methods – cluster and principal component analysis. As can be inferred from the RI values, the potential toxic effect of As and Ni in the sediments is moderate.

土耳其伊斯肯德伦湾表层沉积物重金属污染分析

摘要采用富集和污染因子、污染负荷指数（PLI）和潜在生态风险指数（RI）等指标，对伊斯肯德伦湾沉积物中某些重金属积累造成的生态风险进行了评估。所研究的重金属浓度依次为：Fe>Ni>Mn>Cr>Zn>Cu>As>Pb>Cd>Hg。Ni和As的EF值最高。这种情况很可能是由于该地区存在铁、农药和化肥厂。根据美国环境保护局的说法，镍、砷、锰和铬可能对沉积物中的动物群落产生有害影响。根据RI的说法，4号研究点比其他7个研究点污染更严重，毒性更强，生态风险“中等”。Pearson相关系数采用多变量方法——聚类分析和主成分分析。从RI值可以推断，As和Ni在沉积物中的潜在毒性作用是中等的。
