“…Linear alkylbenzenes (LABs) have been utilized as markers of domestic waste, as they are raw materials in manufacture of linear alkylbenzene sulfonates, a widely used anionic surfactant (Eganhouse et al, 1983), and may be disposed to the environment as residues (1-3%) of commercial detergents (Eganhouse et al, 1983;Chalaux et al, 1995;Zeng et al, 1997). In fact, LABs have been ubiquitously detected in various environmental matrices, such as sediment (Eganhouse et al, 1983;Ishiwatari et al, 1983;Zhang et al, 2012;Liu et al, 2013a), municipal wastewater effluent (Eganhouse et al, 1983;Peterman and Delfino, 1990), river runoff (Takada and Ishiwatari, 1987;Ni et al, 2008), and biota (Murray et al, 1991;Phillips et al, 2001;Tsutsumi et al, 2002).…”
