Various experiments have been conducted on the effect of both high and low electromagnetic radiations on man and animals especially rabbit and rats. However, much work has not been done on fauna and flora with fragile systems. This work centres on the short term effect of low frequency electromagnetic field on earthworms (Lumbricus sp.). The experiment was carried out using a population of earthworms exposed to electromagnetic field of frequency of 36kHz and 42kHz for four hours daily for a period of nine days. Statistical analysis showed that there was a decrease in the mass of earthworms exposed to fields at 42 kHz and 36 kHz while the control experiment showed no such decrease.
