Consequences of trace metal cocktail exposure in zebra …
2020/4/15· Calcium can reduce the accumulation and toxicity of several metals, but soil acidifiion in cities leads to a decrease in bioavailability of this element. The objective of this study was to investigate the accumulation and toxicity of a trace metal cocktail representative of urban exposure on passerine s, and test the importance of calcium availability on these toxic effects.
