The USEtox model as one of LCIA models is an instrument to characterize the human toxicity impact. The model measures the intake of metals by population with meat products. The USEtox is the only model including geographical separation and wide database with organic and nonorganic chemicals. However, the USEtox does not provide any regional information, as ecological or geological specifications of areas included into the model. There is also a lack of data about metals concentrations in the database. Current investigation proposes an approach to reduce these limitations using results of bioindication studying– chemical composition of pork meat samples. Results of bioindication express assessing and forecasting changes in biotas under the anthropogenic influence locally in 3 settlements of “Central Asia” district. We extrapolate them into the USEtox model database, to extend it with concentrations of heavy metals Cr, Zn and As in the meat of pork. Characterization factor is proposed to assess their potential toxicity in soil and air in the region “Central Asia”.
