The use of carbon monoxide (CO) and radon (222Rn) during 1 year continuous monitoring in Bucharest, Romania in relation with other air pollutants (ozone—O3, nitrogen dioxide—NO2, sulphur dioxide—SO2, airborne particulate matter PM10), air quality indices, meteorological variables and planetary boundary layer heights has provided relevant information about lower atmospheric dynamics. Annual average air daily mean CO (328.72 ± 100.02 µg/m3) and 222Rn (38.43 ± 17.68 Bq/m3) do not exceed the threshold limits established by European legislation. Statistical analysis of CO and 222Rn temporal trends revealed their suitability as tracer gases for urban air pollution.
