RESULTS
Based on visual observations, all solutions were clear except 50. 500 and 5000 mg/L which were cloudy. All
solutions had air bubbles collecting on the inside of 'est vessels. Mortalities were 0. 0,0,100,100, and 100%,
respectively. All water quality parameters were wrt-.in acceptaole limits. Loading (0.08 g/L) was also within acceptable limits.
CONCLUSIONS
H-20431 exhibited moderate toxicity in a 96-hour. unaerated, static acute test using fathead minnows, Pimophales promelas.
