Daphnia magna populations were exposed to a series of concentrations of woodwaste leachate over a 21 day period. Impacts were assessed through observed reproductive impairment, growth limitations and adult mortalities. Two chemical parameters, Acidity @ pH 8.3 and Chemical Oxygen Demand were monitored concurrently to correlate levels of these indicators with impacts observed in the bioassay test.
