Investigation of the competitive effects of copper and zinc on fulvic acid complexation: modeling and analytical approaches
Cu and Zn are physiologically vital metals facilitating the proper functioning of many enzymes. However, a flux in anthropogenic activities have elevated the concentrations of these metals in natural waters causing the biological requirements to be exceeded and raising concern in how these metals will affect aquatic organisms. When multiple metals exist in natural waters, a non-additive toxicological effect can occur, where the sum of the metal concentrations becomes more or less harmful than that of the individual metals themselves. The most bioavailable, and thus the most toxic solution species, ...
