Trials are made with laying hens divided into 4 groups, which are being given rations containing lead and cadmium corresponding to those existing in regions with high technogenic Clark. Two new criteria are proposed for improvement of the efficiency of anthrozoocenosis management, which define the chemical heterogeneity of the biosphere at organism and sub-organism level: distribution Clark and safety Clark. Differences are found both in the organotropism of tested elements and in their distribution. The criterion safety Clark shows some irregularities in the legal regulations with regard to the cadmium content of the laying hen products.
