Linear Alkylbenzenesulphonates (LAS), a major anionic surfactant used in laundry products, can be measured specifically in the environment by instrumental analysis. In addition to a desulphonation-gas chromatography approach, a method based on high performance liquid chromatography has been developed. The main features of the methods are outlined, and LAS concentrations measured in sewage sludge, sediments and sludge amended soils are reported. Knowledge of usage volumes, sewage treatment practices and environmental transport and transformation mechanisms has been used to predict concentrations of LAS. These calculated concentrations were found to agree well with those actually measured in the environment. Both measured and calculated ambient concentrations of LAS are below those which could produce potentially adverse effects in representative surface water, benthic and terrestrial organisms.
直链烷基苯磺酸盐（LAS）是洗衣产品中使用的一种主要阴离子表面活性剂，可通过仪器分析在环境中进行特定测量。除了脱磺化-气相色谱法外，还开发了一种基于高效液相色谱的方法。概述了这些方法的主要特点，并报告了在污水污泥、沉积物和污泥改良土壤中测得的LAS浓度。利用使用量、污水处理实践以及环境迁移和转化机制的知识来预测LAS的浓度。发现这些计算出的浓度与在环境中实际测得的浓度非常吻合。LAS的实测和计算环境浓度均低于可能对代表性地表水、底栖生物和陆地生物产生潜在不利影响的浓度。
