Abstract Heavy metal poisoning is the accumulation of heavy metals, in toxic amounts, in the soft tissues of the body. Symptoms and physical findings associated with heavy metal poisoning vary according to the metal accumulated. Many of the heavy metals, such as zinc, copper, chromium, iron and manganese are essential to body function in very small amounts. But, if these metals accumulate in the body in concentrations sufficient to cause poisoning, then serious damage may occur. In this study, we planned to test toxic effects of cadmium, aluminum either alone or combined with each other on sensitive organs as kidney, liver, spleen and lymph nodes. Furthermore we are interested to know whether zinc as antioxidant can recover their toxic effect. We suggest that the toxicity of combined two toxic metals is not equal to their summation of both. Again, does zinc is able to defeat them as a single toxicant or combined together? The experimental work in this study was designed as the following |
