Air pollution spikes throughout Croatia

The Croatian Ministry of the Environment and Green Transition has warned of air pollution across most of the country in previous days. It expects improvement over the weekend.

“In recent days, with the arrival of colder weather and the start of the heating season, a significant increase in the concentrations of air pollutants has been recorded, especially particulate matter (PM10 and PM2.5) across most of Croatia,” the Ministry of Environmental Protection and Green Transition said.

Measuring stations of the State Network for Continuous Monitoring of Air Quality, as well as local stations in most of Croatia’s mainland, are recording a significant increase in the concentrations of air pollutants, including PM10 and PM2.5 particles.

Especially in Zagreb, Sisak, Kutina, Koprivnica, Bjelovar, and Slavonski Brod, monitoring stations registered levels as high as 100 micrograms per cubic meter at times. It is several times above the limit defined by the regulations, the update reads.

The increase in concentrations is primarily driven by emissions from household heating

Two to three times higher values than usual were also recorded at the station in the village of Desinić, on the border with Slovenia. It demonstrates that PM particulate air pollution in Croatia is not exclusively a local or urban issue, but a regional challenge, the ministry stressed.

The cause of the increase in concentrations are primarily emissions from household heating, particularly fueled by solid fuels: wood and coal, the update underlines. The situation is further aggravated by stable weather conditions, the lack of wind, and the occurrence of a temperature inversion.

An additional contribution to air pollution comes from traffic

In urban areas, especially in Zagreb, transportation enhances air pollution. Its impact has intensified in recent years due to the constant growth in the number of vehicles, according to the ministry.

Although wood heating remains the most significant source of PM, all emission sources, including traffic and industry, are amplified in such stable meteorological conditions, the ministry added.

Wind and warmer weather are expected to improve air quality

The ministry claims that current concentrations aren’t causing acute health problems. However, long-term exposure to excessive concentrations of PM increases the risk of respiratory and cardiovascular diseases and shortens life expectancy.

Particularly vulnerable are sensitive population groups such as the elderly, children, adolescents, pregnant women, and people suffering from respiratory and cardiovascular diseases.

The ministry advised citizens to monitor the air quality forecasts of the Croatian Meteorological and Hydrological Service (DHMZ) and the information on the Air Quality Portal. The portal offers an overview of the current air quality situation in the country with real-time data.

The ministry also recommended that citizens, particularly people with chronic illnesses, the elderly, and children, reduce outdoor activities during periods of such excessive concentrations.

In cooperation with the state institutions and local authorities, the ministry is implementing measures defined in air quality action plans to reduce emissions. DHMZ is currently implementing several projects on air protection and is preparing new ones.

An improvement in air quality is expected over the weekend, when temperatures will rise and the southwesterly wind will strengthen, the ministry said.
