Additional information

Probit analysis was applied to the data from the definitive experiment. The EC20, EC50 and EC80 values, those effective concentrations that caused 20%, 50% or 80% reduction in respiration rate relative to untreated controls, were calculated. The EC50 value was 305 mg/L, with 95% confidence limits of 177 to 558 mg/L. The probit analysis indicated a poor fit, and the values should be treated with caution.
