Air pollution in urban areas

In 2002, the national annual average of the integrated air pollution index was 5.85.

City Chisinau. In year 2002 the average annual concentration of nitrogen dioxide exceeded the existing air quality standard (maximum admissible concentration, MAC) by a factor of 1.29, the formic aldehide, by 1.9.

Comparing to the year 2001, the pollution with nitrogen dioxide (annual average values) increased while the particulates, carbon monoxide and formic aldehide, decreased.

City Balti. In 2002 the admissible average annual concentrations were exceeded for particulates (1.9 MAC); nitrogen dioxide (1.5 MAC); sulphur dioxide (1.1 MAC) and formic aldehide (2.6 MAC).

Comparing to the year 2001, pollution with nitrogen dioxide and formic aldehide (annual average values) increased while the level for particulates, carbon monoxide and sulphur dioxide decreased.

City Tiraspol . In year 2002 the admissible annual mean was exceeded only for formic aldehide (1.8 MAC). Comparing to 2001, pollution with nitrogen dioxide, formic aldehide, phenols and carbon monoxide (annual average values) increased while the particulates, carbon monoxide and sulphur dioxide decreased.

City Ribnita. In 2002 the admissible annual mean was exceeded only for nitrogen dioxide (1.1 MAC). In terms of monthly average values, the highest level of pollution was registered for nitrogen dioxide (1.5 MAC), in May. Other ingredients did not exceed the admissible levels. Comparing to the previous year, air pollution with sulphur dioxide increased while the level of soluble sulphate, particulates and carbon monoxide, decreased.

City Bender. In year 2002 no significant changes in air quality were recorded, comparing to 2001. The admissible annual average values were not exceeded.

At the national level, in year 2002 the average annual concentrations of formic aldehide increased in comparing with 2001, the sulphur dioxide and nitrogen dioxide decreased and the carbon monoxide and particulate level remained the same.

In spatial perspective, the air pollution indexes varied between 0.91 (Bender) and 11.23 (Chisinau). The highest average annual concentrations of pollutants were recorded as follows: for particulates (1.7 MAC), sulphur dioxide (1.2 MAC), nitrogen dioxide (1.5 MAC) and formaldehide (2.6 MAC) - in Balti; for carbon monoxide (0.5 MAC) - in Tiraspol ; for phenols (0.8 MAC) in Chisinau and for soluble sulphate (0.07 MAC) in Ribnita.
