Abstrakt: mill discharges to plant life in receiving waters led to an evaluation of the toxicity of 46 dyes. Toxicity assessment was performed using the standardized 96-hour Selenastrum capricornutum chronic toxicity test at 1 mg/L of the active colorant in the dyes. All except two of the dyes examined have anionic colorants, many of which are reactive and/or metal complexes. Only the two cationic dyes demonstrated toxicity. The two cationic dyes resulted in EC50 concentrations of 0.025 and 0.247 mg/L of colorant. [ABSTRACT FROM AUTHOR]
