Abstract
The cosmopolitan genus Artemia occurs both in saline or hypersaline waters and Artemia species are sensitive indicator organisms for environmental contamination. Scientists propose that the brine shrimp ( Artemia) is a very suitable candidate for the development of identifying chemicals with adverse effects in aquatic ecosystems. In the present study, we investigated 24 h the short-term toxicity of lead acetate on Artemia parthenogenetica by using electron microscopy techniques. The ultrastructural changes were studied control group and experimental group. Analysing cellular structure, structure of organelles and vacuolization were observed. The number of cells based on the toxic effects of lead acetate was increased compared with the control group.
