Red alarm level: fine dust values in Vienna three times above the WHO border

In Vienna, the reports on high fine dust values are currently increasing, which according to the latest measurements are three times as high as the limit recommended by the World Health Organization (WHO). The city faces a serious air quality crisis, while weather apps and real-time maps classify the air as "unhealthy". These alarming values call up numerous questions, especially with regard to the health effects and causes.

The fine dust pollution in Vienna has risen sharply in the past few days. Environmental doctor Hans-Peter Hutter explains that last Sunday values between 40 and 50 micrograms per cubic meter PM2.5 were measured, which represents a significant exceeding of the recommended limit of 15 micrograms. These particles are so small that they can penetrate deep into the lungs and are therefore potentially harmful to health.

causes of the high fine dust pollution

The causes of the poor air values are diverse. One of the main factors is the exhaust gases of vehicles that, combined with the weather conditions, significantly worsen air quality. There is currently an inversion weather situation in which warm layers of air hold onto the colder layers underneath. This remains the fine dust in the city and cannot distribute itself. Hutter emphasizes that no wind blows to dispel the particles, which leads to a kind of "smog bell" over the city.

Not only traffic contributes to air pollution. Hutter also points out that air flows from neighboring countries and regional immissions are further sources of fine dust pollution. These factors together represent a serious challenge for public health. In particular, people with respiratory diseases and seniors are particularly at risk.

Despite the alarming fine dust values, Hutter encourages the population to continue to move outside, but with measure. He advises to avoid excessive physical exertion and refrain from unnecessary car journeys so as not to increase the stress.

Awareness of air quality has increased in recent years, in particular by spreading weather apps, the air-polluted air. Hutter welcomes this, but warns that not all apps use reliable data. Official measurements for fine dust pollution are essential to get a realistic assessment of the air quality.

Overall, the terrifying fine dust values in Vienna show that there is an urgent need for action. The city must take suitable measures to sustainably improve air quality and protect the health of citizens.
