The results of the measurements of black carbon and fine aerosol content in Beijing and in the background region 50 km north-east of the capital of China are analyzed. The measurements were carried out for many years, mainly in the autumn. A reduction in the concentration of black carbon, having regional character, has been revealed. An earlier conclusion about the reduction, on average, of the relative contribution of soot aerosol with the growth of air the turbidity has been confirmed.
