Abstract |
The Mount-Norberg test, which employs a measure of the size of three broods over seven days, has been used extensively in toxicity testing. The authors have applied it to estimating sublethal ecosystem effects of complex effluents in the Raisin River drainage (of Michigan) on the downstream, food-rich communities of Lake Erie. Using an expanded but traditional life-table approach, the authors observed that the 7-day test provided estimates of natality (Mx) which significantly differed from bioassay results of 14 to 21 days duration. Therefore the authors conducted an analysis of interactions between duration (times of 0-7, 0-14, 0-21, 0-28 days) and treatment (toxicant levels), and found an appropriate duration of 14 days for food-rich Lake Erie environments. |
