The article discusses the toxicity of the non-aqueous phase liquid, linear alkylbenzene, to the nematode, Caenorhabditis elegans in soils from Edinburgh, Scotland. According to the authors, linear alkylbenzene (LAB) is used in the manufacture of the detergent, linear alkylbenzene sulphonate, and also as insulating oil for underground electricity transmission cables. They found a clear increase in mortality with increase in linear alkylbenzene in the soil. They indicate that LAB in was not lethal to earthworms in soils up to 1% concentration.
