The concentrations of synthetic surfactants in wastewater can exceed 30 g/L. The hazard posed by these substances needs to be demonstrated. E Color powder laundry detergent exhibited stronger toxicity toward Vigna radiata seedlings than Arau liquid laundry detergent at all the concentrations tested. The incubation in all Petri dishes lasted for 96 h. Arau caused no toxic effect at concentrations of 0.05 and 0.5 g/L; E Color produced toxic effects at these concentrations. The new data show that Vigna radiata is applicable for assessing the hazard of pollutants.
