Remark : In Lake Erie wtaer at 25 degrees Celsius 424 mg/l, 300 mg/l, at 17 degrees<br />
Celsius 300 mg/l and at 800 mg/l all animals were killed. The 100 hr EC50<br />
at 23 degrees Celsius in doudble distilled water has been reported at 524<br />
mg/l, pH 9.5. Furthermore, at 23 degrees Celsius for a 100-hr exposure the<br />
EC50 was 552 mg/l at a dissolved oxygen tension of 6.5 mg/l, but the EC50<br />
was only 267 mg/l when the dissolved oxyg en tension dropped to 1.53 mg/l.<br />
