Biological Systems and Organisms

We investigate the use of antioxidant enzymes and the South African Scoring system in pollution monitoring from Acid Mine Drainage (AMD) and commercial agricultural activities. The Yellow Jacket River receives effluent from pyrite mining from Iron Duke Mine while Mazowe River receives runoff from surrounding commercial agriculture. The quality of the water in the two systems is being investigated by comparing biomarkers measured from the field (exposed organisms) and those organisms from a reference site.

Research Keywords:
