Abstract

The results of dispersion analysis indicate that clinical, radiological and sonographic signs of articular syndrome and extra-articular manifestations in RA depend on the degree of contamination of atmospheric air and soil with xenobiotics. It means that cnanges in the trace element composinon of the soil and atmosphenc air (N02. FH. C'd. AL Pb and HF), depending on tlie RA patients' Living areas, contribute to the rate of disease progression.
