RXSOLTS Based on visual observa' i ans, all test solutions wore cliar with no color, except for the 5000 mg/r. test solution, which was cloudy, white in color. The 5000 mg/L test solution waa cloudy, white in color. Mortalities were 0, 0, 0, 0, 0, and 100':, respectively. The &6-hour LC50, based on nominal concentrations and mortality, was between 500 and 5000 mg/L. All water quality parameters were within acceptable limits. COHCLCTSIOMS H-21954 exhibited low toxicity in a 96-hour, unaerated, static acute test using fathead minnows, Pimephales promelas. WORK BY: ^v^^f 2S W.
