Abstract

Water pollutants from domestic wastewater (major ingredients of detergent or soap, bactericides used for medicated soap, fablic softener, hair rinse and so on) were tested with bread yeast (AOY-I) for detecting their interactive toxicity whose endpoint was growth inhibition. Lethal effects were observed on systems exposed to cationic surfactant or synthetic surfactant-organochlorine bactericide mixed samples. Strong inhibition were observed on systems LAS and fluorescent whitener (DAS-I). No inhibition were observed on systems exposed to AE, soap and mixed samples containing soap.<br>Synergistic effects were clearly shown on systems exposed to organochlorine bactericides with synthetic surfactants especially in cases of including AE. These results suggested that synthetic surfactants might cause damage to cell membrane consisted of phospholipids, then absorbed other toxic chemicals into cells.
