Abstract:

The purpose of this paper was to determine the content of cadmium, chromium elements in feed additives, and to determine distribution of organs in pig and chicken, and the migration in soil. The results showed that heavy metals in the supplemented diet are partially accumulated in meat and liver and the rest is excreted in feces or accumulated in soil. In this paper, an adsorption model of the contents of cadmium, chromium elements in different soil depth with the soil of different depth and different depth soil moisture was established. Through the nonlinear MATLAB7.1 fitted the adsorption coefficient and transfer coefficient of cadmium and chromium elements of different soil distribution. The relative errors are within 0.5%, and the reliability is more than 95%.

Keywords: Adsorption model, cadmium, chromium, meat products, nonlinear MATLAB, soil.
