A bioassay with a single toxicant concentration of 500 mg/L is not deemed adequate to justify a nontoxic designation. When screening bioassays are performed, initial screening bioassays must be conducted at two concentrations bracketing the 500 mg/L level. One of these concentrations must be 750 mg/L. dr nacima bouzeroura
