The paper characterizes the state of air pollution on the ground of Wroclaw in the period of 1990 to 1999. The base air contamination for Wroclaw: dust, SO2, NO,, F, Pb. Cd, B(a)P were analyzed, also the source of emission, monitoring and method of indicates were discussed. The investigations show significant decrease of the concentration: dust, SO,, the high level of the concentration of NO, and F with the increasing tendency at the end of the observation period and the insufficient monitoring of the particularly dangerous contamination for the health: Pb, Cd, B(a)P. The received results indicate the necessity of the reorganization of the existing air monitoring system with particular regard to communication contamination. In this work the new principle for the air quality control in Wroclaw has been proposed.
