^ Stonefly bioassay was done at Denver, Colo., and at Salt 

 Lake City, Utah. Denver tests were in soft water (35 mg/l TDS), 

 non-aerated, 60 F. Salt Lake City tests were in hard water (150 

 mg/l TDS), aerated, 48-50 F. Response was death. 



- Daphnia pulex and Simocepfialus serrulatus bioassay was 

 done at Denver, Colo., in soft water (35 mg/l TDS), non-aerated, 

 60 F. Daphnia magna bioassay was done at Pennsylvania State 

 University in hard water (146 mg/l TDS), non-aerated, 68 F. 

 Response was immobilization. 



^ Fish bioassay was done at Denver, Colo., and at Rome, N.Y. 



Denver tests were with 2-inch fish in soft water (35 mR/l TDS), 

 non-aerated; trout at 55 F; other species at 65 F. Rome tests 

 were with 2-2 '/2-inch fish in soft water (6 mg/l TA: pH 5.85- 

 6.4), 60 F. Response was death. 



■i Gammarus bioassay was done at Denver, Colo., in soft 

 water (35 mg/l TDS), non-aerated, 60 F. Response was death. 



^ Becomes bound to soil when used according to directions, 

 but highly toxic (reflected in numbers) when added directly to 

 water.
