Mount, D., N. Thomas, T. Norberg, M. Barbour, AND T. Roush. EFFLUENT AND AMBIENT TOXICITY TESTING AND INSTREAM COMMUNITY RESPONSE ON THE OTTAWA RIVER, LIMA, OHIO. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/3-84/080 (NTIS PB85102333).
Description:
The research described in this report had three objectives: (1) determination of effluent and ambient stream toxicity to Ceriodaphnia, fathead minnows, and indigenous species; (2) definition of the response of the biological community to point-source discharges; and (3) evaluation of the effectiveness of toxicity testing techniques in predicting ambient toxicity to indigenous communities. Based on toxicity measurement of effluents and river water, tests did predict the resulting toxicity downstream from the discharges.
