Alkylbenzene sulfonates (ABS) are surfactants widely used in residential and commercial products. To support the environmental risk assessment of these compounds, acute toxicity three ABS, linear (n-ABS), branched (BABS), alkyl phenoxybenzene (APBS), was evaluated using six aquatic organisms from different trophic levels (algae, daphnid, amphipod, mussel, snail, fish). This approach allowed direct comparisons among species to provide insights into sensitivity surfactants, compounds information on those with a lack ecotoxicity data (e.g., BABS, APBS). Endpoints related survival, growth, physiological changes were recorded. Comparisons ABS based nominal concentrations due absence pure analytical standards for APBS. However, methods developed BABS available n-ABS, so effects also measured concentrations. Results showed differences all exposed except snails, which similar most tolerant species. Based concentrations, EC50/LC50 values APBS ranged, respectively, 5.0 17.8 mg/L, 7.3 25.6 3.5 > 100 mg/L. The sensitive n-ABS fish, mussels, amphipods, while amphipods mussels APBS, respectively. Species BABS. results indicated that varied 1.24 13.13 mg/L 1.53 5.21 range reported surface waters. Amphipods could therefore be relevant model
