A survey of inhibitory effects of nonionic and anionic surfactants, including a soap, used in washing agents, on the growth on three species of freshwater phytoplankton,Selenastrum capricornutum, Nitzschia fonticolaandMicrocystis aeruginosawas conducted. Based on the specific growth rate, μu estimated from a short period (2 or 3 days) cultivation of test algae, the growth inhibition was determined using EC50values where μu in the culture medium with surfactant decreased 50% of that without surfactant.The EC50values of nonionic and anionic surfactants tested here forS. capricornutumranged from 2 to 50 mg l−1and from 10 to 100 mg l−1, respectively. The tolerances of three species of algae tested with three surfactants, LAS, AE (EO:9) and soap, were different and the inhibitory effects were species specific. EC50values of LAS, AE (EO:9) and soap forS. capricornutumwere 50–100, 4–8 and 10–50 mg l−1, respectively. Those forN. fonticolawere 20–50, 5–10 and 20–50 mg l−1, and those forM. aeruginosawere 10–20, 10–50 and 10–20 mg l−1, respectively.
