What pollutants must be continuously measured for car park air quality management?

The correct answer focuses on the specific pollutants that have a significant impact on air quality in enclosed spaces like car parks. Carbon monoxide (CO) is a critical pollutant in such environments because it is produced by vehicle emissions and can accumulate to hazardous levels without proper ventilation. Nitrogen dioxide (NO2) is another important pollutant as it arises from combustion processes in vehicle engines and can affect respiratory function. Particulate matter (PM10) includes tiny particles that can be inhaled and cause health issues, particularly in confined spaces where vehicle exhaust may not disperse effectively.

Continuous measurement of these pollutants in car parks is essential to ensure the health and safety of individuals using these spaces. Monitoring allows for effective ventilation strategies to be implemented, minimizing human exposure to these harmful substances. Thus, the selection of CO, NO2, and PM10 aligns perfectly with best practices for indoor air quality management in environments with high vehicle usage.
