TOXICITY OF BORON TO RAINBOW TROUT: A WEIGHT-OF-THE-EVIDENCE ASSESSMENT

摘要

From the large data set available on the toxicity of boron to aquatic organisms, the toxicity of boron to the early life stages of rainbow trout(Oncorhyncus mykiss)is the seminal issue relative to setting water quality and effluent standards. Issues associated with the early life stage studies are the flat concentration-response curve, the low threshold of toxicity, and Teratogenic effects observed. Recent laboratory and field studies offer new experimental data that make a weight-of-the-evidence Assessment timely.
