Macau (MNA) – The Meteorological and Geophysical Bureau (SMG) warned residents that air quality monitoring stations in Macau have recorded a significant increase in air pollutant concentrations starting on Friday and lasting until today.
This increase was due to weak general wind speed unfavorable for the diffusion of air pollutants.
The higher concentration of pollutants and fine particles was recorded in the High Density Residential Area Taipa monitoring station, which as of 9:25 am registered a Daily Air Quality Index of 129 or ‘unsuitable’ for people who have cardiac or respiratory disease, symptom might become slightly worse.
The sub-index of pollutants measures respirable suspended particulate (PM10), fine suspended particulate (PM2.5), nitrogen dioxide (NO2), ozone (O3), sulphur dioxide (SO2) and carbon monoxide (CO), and is calculated daily concentrations and related influences to human health.
Therefore the SMG recommended people who have cardiac and respiratory disease are advised to reduce their physical exercise and outdoor activities.
