RESUMO
Many studies show the toxic effects of cadmium and its active role in cancerous. So in this perspective, we try to investigate these toxic effects in workers of some specific industries with the cadmium is considered as one of its substance components, such as batteries pigments' and paintings. We analyze in our study the serum of some patients suffering by the cancer and working in direct contact with the cadmium, and compare the results with that concerning a sample of worker suffering by the cancer but working in industries clean by this material. To Perform our study, we use the atomic absorption spectrometer assay to calibrate the level of cadmium in the serum, and we follow the student test between groups in the statistical study of the laboratory results. This research shows the rising of the level of cadmium in the workers who are in direct contact with this material; where it reached the double of whom work in clean industries and it reveal its active role in the development of the cancer
