To evaluate the heavy metal contamination, ecological risk and possible sources at Saudi Yanbu coastline, 30 sediment samples were collected for Fe, Pb, Ni, As, Zn, Cu, Cr, Co, Al, Sb, Cd, and TOC analyses using ICP-MS. The potential ecological risk index (PERI), enrichment factor (EF), contamination factor (CF), potential contamination index (Cp), geoaccumulation index (Igeo), soil pollution index (SPI) were calculated and interpreted, and multivariate analyses were applied. The results indicated the following order for metal averages: Al (8573 μg/g) > Fe (5895 μg/g) > Mn (192 μg/g) > Zn (80.4 μg/g) > Cu (35.87 μg/g) > Cr (27.11 μg/g) > Ni (23.5 μg/g) > Co (8.29 μg/g) > Pb (7.72 μg/g) > As (6.83 μg/g) > Sb (0.50 μg/g) > Hg (0.33 μg/g) > Cd (0.30 μg/g). Average levels of As, Ni, Zn, Co, Cd, and Pb values were greater than those reported from many coastal sediments from the Red Sea, Gulf of Aqaba, Arabian Gulf and Mediterranean Sea, as well as the sediment quality guidelines. The results of potential ecological risk revealed very high risk for Cd, high risk for Hg, considerable risk for Cu, Sb, and As, moderate risk for Pb and Ni, and no to low risk for Zn and Cr. The moderately severe enriched HMs (Cd, Zn, Cu, Hg) and the moderate enriched ones (Pb, Co, As) were originated mostly from anthropogenic sources related to industrial, agricultural, urbanization and fishing activities. The no and minor enriched HMs (Fe, Al, Ni, Cr, Sb) were mostly related to lithogenic factors related to rock weathering and atmospheric inputs.

沙特阿拉伯红海沿岸盐步地区沿海沉积物重金属污染评估

为了评估沙特盐布海岸线上的重金属污染,生态风险和可能的来源,使用ICP收集了30个沉积物样品中的Fe,Pb,Ni,As,Zn,Cu,Cr,Co,Al,Sb,Cd和TOC分析-多发性硬化症。计算和解释了潜在的生态风险指数(PERI),富集因子(EF),污染因子(CF),潜在污染指数(Cp),地质累积指数(Igeo),土壤污染指数(SPI),并进行了多变量分析。结果表明金属平均值按以下顺序排列:Al(8573μg/ g)> Fe(5895μg/ g)> Mn(192μg/ g)> Zn(80.4μg/ g)> Cu(35.87μg/ g)> Cr(27.11μg/ g)> Ni(23.5μg/ g)> Co(8.29μg/ g)> Pb(7.72μg/ g)> As(6.83μg/ g)> Sb(0.50μg/ g)> Hg( 0.33μg/ g)> Cd(0.30μg/ g)。砷,镍,锌,钴,镉的平均含量 Pb值和Pb值均高于红海,亚喀巴湾,阿拉伯湾和地中海沿岸许多沉积物以及沉积物质量准则的报告值。潜在的生态风险结果表明,镉的风险很高,汞的风险很高,铜,锑和砷的风险很高,铅和镍的风险中等,而锌和铬的风险不低。中度重度富集的HMs(镉,锌,铜,汞)和中度重度富集的HMs(Pb,Co,As)主要源自与工业,农业,城市化和渔业活动有关的人为来源。没有和少量富集的HMs(铁,铝,镍,铬,锑)主要与与岩石风化和大气输入有关的成岩因子有关。阿拉伯海湾和地中海以及沉积物质量指南。潜在的生态风险结果表明,镉的风险很高,汞的风险很高,铜,锑和砷的风险很高,铅和镍的风险中等,而锌和铬的风险不低。中度重度富集的HMs(镉,锌,铜,汞)和中度重度富集的HMs(Pb,Co,As)主要源自与工业,农业,城市化和渔业活动有关的人为来源。没有和少量富集的重金属(铁,铝,镍,铬,锑)主要与与岩石风化和大气输入有关的成岩因子有关。阿拉伯海湾和地中海以及沉积物质量指南。潜在的生态风险结果表明,镉的风险很高,汞的风险很高,铜,锑和砷的风险很高,铅和镍的风险中等,而锌和铬的风险不低。中度重度富集的HMs(镉,锌,铜,汞)和中度重度富集的HMs(Pb,Co,As)主要源自与工业,农业,城市化和渔业活动有关的人为来源。没有和少量富集的重金属(铁,铝,镍,铬,锑)主要与与岩石风化和大气输入有关的成岩因子有关。并且不会降低锌和铬的风险。中度重度富集的HMs(镉,锌,铜,汞)和中度重度富集的HMs(Pb,Co,As)主要源自与工业,农业,城市化和渔业活动有关的人为来源。没有和少量富集的重金属(铁,铝,镍,铬,锑)主要与与岩石风化和大气输入有关的成岩因子有关。并且不会降低锌和铬的风险。中度重度富集的HMs(镉,锌,铜,汞)和中度重度富集的HMs(Pb,Co,As)主要源自与工业,农业,城市化和渔业活动有关的人为来源。没有和少量富集的HMs(铁,铝,镍,铬,锑)主要与与岩石风化和大气输入有关的成岩因子有关。
