Air quality concerns are rising globally, and Latvia is no exception, especially in Riga, where pollution levels have seen dramatic increases this January. With minimal precipitation, weak winds, and a heavy heating season, researchers are observing alarming trends in atmospheric pollution. According to experts, all indicators of air pollution have risen sharply this year, most notably noted in the capital. Specific pollutants like particulate matter and nitrogen dioxide are typically associated with heating, but unexpected increases in sulfur dioxide have also been recorded, which is unusual for the area.

Prof. Šteinberga attributes the deteriorating air quality primarily to the high number of diesel vehicles in the city, which contribute small amounts of sulfur. However, during the winter months, the pollution generated from heating systems presents the most significant concern. Comparing the period from January 1 to February 9 of this year to the same timeframe last year, there has been an astonishing 370% increase in particulate pollution levels measured in the Mīlgrāvis area. This substantial rise highlights the urgent need for targeted air quality management and pollution reduction strategies.

The continuing trend of worsening air quality in Latvia emphasizes the challenges faced by urban areas with high traffic and seasonal heating demands. Given the high levels of atmospheric contaminants, it raises questions about public health and environmental policies. Local authorities and policymakers may need to implement stricter regulations on emissions and invest in cleaner energy solutions to address this pressing issue.
