Remark:
(1) NO2 - nitrogen dioxide, O3 - ozone, SO2 - sulphur dioxide, CO - carbon monoxide, PM10/RSP - particulate matter with an aerodynamic diameter of less than 10 μm / respirable suspended particulates, PM2.5 / FSP - particulate matter with an aerodynamic diameter of less than 2.5 μm / fine suspended particulates.
(2) Concentrations in micrograms per cubic meter (μg/m3).
(3) Pollutant concentrations and AQHI information are based on raw data taken directly from EPD's Air Quality Monitoring Network.
