Specifically, the BLM does this in a way that considers the important influences of site-specific water quality.
Increases in waterborne Ca2+ had a protective effect on Zn toxicity, suggesting that this ion competes with Zn and that they share a common site of biological uptake.
The sites were representative of effluent-dependent or effluent-dominated streams common to the arid western United States of America (arid West) and a wide range of water quality variables were tested.
