cussed. Neither lead nor arsenic acid were found to be toxic. Finally 30 herbicides were<br />

tested for toxicity (Hillaker, 1996). The toxicity determined by this method was compared<br />

with the toxicity reported by the manufacturers using rats, ducks, and quail in classical<br />

LD50 tests; and with trout fingerlings and with Daphnia. The tests with trout fingerlings<br />

and with Daphnia were much more sensitive than the tests with animals. The tests with<br />

Rhizobium were less sensitive than with Daphnia and the trout fingerlings for most <strong>of</strong> the<br />

herbicides but were always more sensitive than tests with animals.<br />
