Textile industry is one of the most polluting industries in the world. It has a high importance in terms of its environment impact, since it consumes a considerably large amount of water and produces highly polluted discharge water. In this work, characterization of toxic organic compounds is proposed. Based on gas chromatography coupled to mass spectrometry (GC/MS) screening analysis, organic micropollutant diversity of textile effluents from a local textile processing factory was investigated. In the present work, physicochemical characterization of the studied textile effluents showed considerably high values of principal pollution parameters above the prescribed discharge water limits. Heavy metals like zinc (Zn), copper (Cu), iron (Fe), nickel (Ni), cadmium (Cd), chromium (Cr), and lead (Pb) were found to be present within the permissible limits. The results of GC/MS revealed the presence of various organic compounds belonging to a wide range of chemical classes. Main groups of chemical compounds detected in these effluents were aromatic carboxylic acids, alkanes, aromatic amines, phthalates, aliphatic carboxylic acids, and linear aliphatic alcohols. The results of this study allowed significant contributions to the chemical characterization of textile industry contaminants and identification of indicators that can be considered an important tool for assessment of the potential impact of textile activities to the contamination of aquatic environment and health hazard.

摩洛哥非斯市纺织工业废水中特定微污染物的化学表征

纺织业是世界上污染最严重的行业之一。就其环境影响而言，它具有很高的重要性，因为它消耗大量的水并产生高度污染的排放水。在这项工作中，提出了有毒有机化合物的表征。基于气相色谱与质谱联用 (GC/MS) 筛选分析，研究了当地纺织加工厂纺织废水中有机微量污染物的多样性。在目前的工作中，所研究的纺织废水的物理化学特征表明，主要污染参数值高于规定的排放水限值。重金属，如锌 (Zn)、铜 (Cu)、铁 (Fe)、镍 (Ni)、镉 (Cd)、铬 (Cr)、和铅 (Pb) 的含量在允许范围内。GC/MS 的结果表明存在属于广泛化学类别的各种有机化合物。在这些流出物中检测到的主要化合物组是芳香羧酸、烷烃、芳香胺、邻苯二甲酸盐、脂肪羧酸和线性脂肪醇。这项研究的结果对纺织工业污染物的化学表征和识别指标做出了重大贡献，这些指标可被视为评估纺织活动对水生环境污染和健康危害的潜在影响的重要工具。在这些流出物中检测到的主要化合物组是芳香羧酸、烷烃、芳香胺、邻苯二甲酸盐、脂肪羧酸和线性脂肪醇。这项研究的结果对纺织工业污染物的化学表征和识别指标做出了重大贡献，这些指标可被视为评估纺织活动对水生环境污染和健康危害的潜在影响的重要工具。在这些流出物中检测到的主要化合物组是芳香羧酸、烷烃、芳香胺、邻苯二甲酸盐、脂肪羧酸和线性脂肪醇。这项研究的结果对纺织工业污染物的化学表征和识别指标做出了重大贡献，这些指标可被视为评估纺织活动对水生环境污染和健康危害的潜在影响的重要工具。
