The toxic effect of heavy metal ( Cadmium ) was investigated using a species of freshwater aquatic insect - nymph of Ephemeroptera , Cloeon dipterum ( L.) . This heavy metal was found to have a significant effect on the fine structure of the gills in proportion to the concentration of Cadmium used ( 0.1 ppm, 0.5 ppm and 1 ppm ) . The results were supported by ultra structural observation on different types of the gills cell organelles ( gill lamella , nucleus , mitochondria , endoplasmic reticulum and other parts of the cell ) .Transmission electron microscopy has revealed the disruption and the damage for the normal cellular organization of the nymph gill cells when the animal exposures for 36 hours in the pollutant media . Most of the freshwater pollution – scientists thought that this kind of aquatic insects can used as biological monitors of heavy metal pollution . The aim of the present study is to investigate the poisoning effects of this heavy metal on the mortality caused by ultra structural damage which is standing behind the death of the animal and human been .
