The concentration of suspended solid particles PM10, or dust with a diameter of up to 10 micrometers, reached 187 micrograms per cubic meter on Kronvalda Boulevard and 237 micrograms per cubic meter on Krišjāņa Valdemāra Street at nine in the morning.
Air quality becomes poor when this indicator exceeds 50, and particularly poor when the daily average concentration of PM10 exceeds 150 micrograms per cubic meter.
Much of the air pollution comes from Saharan dust, as well as local sources of pollution. Air quality is poor in most parts of Latvia, especially in cities.
The situation will improve as the wind shifts from the west, south-west, bringing cooler and cleaner air. In the capital, it will take place on Tuesday afternoon or, at the latest, in the evening.
As the air quality is particularly bad, residents should reduce physical outdoor activities, while sensitive population groups should avoid them completely.
According to the assessment of the World Health Organization, air pollution is the fourth biggest risk to health – after high blood pressure, unhealthy diet and smoking.
