RSSULTS
Based on visupl observations, all solutions were clear, except for the 500 and
5000 mg/L solutions which were cloudy, white in color. Mortalities were 0, 0, 0, 0, 100, and 100%, respectively. The 96-hour LC50, based on nominal concentrations and mortality, was between 50 and 500 mg/L. All water quality parameters were within acceptable limits.
CONCLnSIOHS
H-21209 exhibited slight toxicity in a 96-hour, unaerated, static acute test
using fathead minnows, Pimephales nromelas.
