Abstract:

The objectives of this research are To establish the LC50 of the heavy metals cadmium, copper, arsenic and mercury as well as a CuCd mixture in a ratio equal to LC50 CdLC50 Cu, employing a chemically defined medium such as Aristol To improve procedures for heavy metal bioavailability studies in the field To improvedevelop test procedures using a chemically defined medium and food in 28-day uptake studies To analyze the tissues of the surviving test earthworms as well as those from media of lesser concentrations, blanks and background worm stock To relate the LC50 concentrations of contaminants with the tissue contaminant levels in the earthworms utilized in the toxicity test and To develop first generation interpretations relating soil contaminant levels and bioavailability, and to interpret the fate and transport of heavy metal contaminants.
