TL;DR: The effects of various water chemistry parameters on the toxicity of copper to larval fathead minnows were investigated in this paper, where the effects of water chemistry were found to be similar for different endpoints (growth, survival at different durations).

TL;DR: Exposure of three generations of brook trout (Salvelinus fontinalis) to mean total lead concentrations showed that all second-generation trout exposed to 235 and 474 μg Pb/liter showed positive responses to lead.

TL;DR: In this paper, the role of acid-volatile sulfide (AVS) in determining copper toxicity in sediments from two sites heavily contaminated with copper: Steilacoom Lake, Washington, and the Keweenaw Watershed, Michigan.

TL;DR: In this paper, the influence of acid-volatile sulfide (AVS) on the bioavailability of cadmium and nickel in sediments was investigated and the results support other studies with metal-spiked samples in demonstrating the importance of AVS in determining metal bioavailability.

TL;DR: It is indicated that kidney, liver, and gill tissue accumulated the greatest amounts of cadmium at each water exposure concentration, and that the maximum acceptable toxicant concentration (MATC) for brook trout exposed to Cadmium in Lake Superior water lies between 1.7 and 3.4 μg Cd/liter.
