Thesis Title
Copper and Zinc dynamics and bioavailability in soils amended with biosolids
Read article at Massey Research Online: 
Mr Jeyakumar’s research examines the effect of biosolids derived copper and zinc on forest trees (poplar and pine), mycorrhiza and soil microbial activity. It also focuses on the specific soil factors affecting bioavailability of biosolids derived copper and zinc as well as proposes suitable amendments which can lower the biotoxicity of these metals. The study provided information on improving the current environmental regulations with respect to heavy metals that seek to protect agriculture land, human and animal health, and soil and drinking water quality, in scenarios where biosolids are applied to soil.
