Abstract |
Acute and chronic toxicity tests were conducted to determine the effects of metals combined as mixtures at proposed water quality criteria concentrations and at multiples of the LC50 and MATC obtained from tests on six metals with three aquatic species. Arsenic, cadmium, chromium, copper, mercury, and lead combined at criterion maximum concentrations caused nearly 100 percent mortality to rainbow trout and daphnids (C. dubia) during acute exposure. Fathead minnows were not adversely affected at this or two times this concentration, although a mixture of 4 to 8 times the maximum value caused 15 to 60 percent mortality. Embryo hatchability and survival of rainbow trout were reduced at 4 times this criterion but not at the criterion average concentration. |
