In an effort to assess the coastal water quality in an Algerian Bay, suspended particulate matter (SPM) was analyzed for trace metals and various environmental parameters in Bou Ismail Bay. The trace metal concentrations analyzed by absorption atomic spectrometry followed the decreasing order Al > Fe > Zn > Mn > Ni > Cu > Pb > Co > Cr > Cd > Hg > As (p<0.001). To assess risk, a multiple risk assessment approach was used. The enrichment of particulate metals followed a descending order of Cd > Zn > Ni > Fe > Cu > Co > Hg > Pb > Cr > As. Cadmium and nickel, may enter the bay from anthropogenic non-point sources, had the highest potential ecological risk and biological effect. Nickel contributes 46% to the potential acute toxicity ($\Sigma$TU${}_{\mathrm{i}}$) of the SPM. The combined metals Pb, Cd, Cu, Zn, Cr, Ni, Hg and As had 25%–30% probability of biotoxicity but did not indicate a likelihood of any significant toxic effects based on results from previous amphipod toxicity tests. Generally, the SPM was categorized as being slightly toxic ($\Sigma$TU${}_{\mathrm{i}}$<4).

为了评估阿尔及利亚湾的沿海水质，我们对布伊斯梅尔湾的悬浮颗粒物 (SPM) 中的痕量金属和各种环境参数进行了分析。通过吸收原子光谱法分析的痕量金属浓度遵循递减顺序 Al > Fe > Zn > Mn > Ni > Cu > Pb > Co > Cr > Cd > Hg > As ( p <0.001)。为了评估风险，使用了多重风险评估方法。颗粒金属的富集顺序为Cd>Zn>Ni>Fe>Cu>Co>Hg>Pb>Cr>As。镉和镍可能从人为非点源进入海湾，具有最高的潜在生态风险和生物效应。镍对潜在的急性毒性贡献了 46%（$\Sigma$TU${}_{\mathrm{一世}}$) 的 SPM。组合金属 Pb、Cd、Cu、Zn、Cr、Ni、Hg 和 As 具有 25% 至 30% 的生物毒性概率，但根据之前片脚类动物毒性试验的结果，未表明任何显着毒性作用的可能性。一般来说，SPM 被归类为微毒（$\Sigma$TU${}_{\mathrm{一世}}$<4).
