6. Conclusions
Results of our study suggest that anomalies in cell division processes and chromosome aberration
induced in the Allium cepa root meristem could be a result of the interaction of heavy metals from the
electronic waste leachate. Since the mechanism of DNA toxicity in all biological systems may be similar,
care must be taken as clastogenic effects elicited by e-waste leachate in the cells of A. cepa may spell
doom for all living things exposed to the leachate at the study site. Electronic waste has become a similar
challenge to those posed by other domestic solid wastes but also presents opportunities for recovery,
reuse and recycling of its important components that are generally discarded with proven environmental
and human health hazards. Adequate legislation can create opportunities for former e-waste recycling
programmes integrating the recyclers for improved environmental and health performance.
