| Abstract | ||
| The aim of this study is to evaluate the effect of cadmium on the secretion of goblet cell of the epidermis in earth worm Aporrectodea caliginosa under laboratory conditions. Thirty active adult worms were used in the study which were divided in to four groups in addition control group each with 150g of soil.The following concentrations of cadmium in the soil were (100,200,300,400 and 500) ppm .The experiment lasted for thirty days .The results showed that there is reverse relationship between the cadmium concentrations and cells response degree .It is found that the EC50 effective concentration is 500ppm.The results also showed that the cadmium has a direct effect on the goblet cell in the epidermis .The study demonstrated that there is a decrease in the cells dimension and the appearance of the empty spaces inside them as a result of the emergence of mucus materials on the body surface of the | ||
