Austria uncovers hidden asbestos contamination in roads and public spaces

Asbestos contamination has been discovered in parts of Burgenland, Austria, raising concerns over public health. The harmful mineral was found in crushed rock used on roads, as well as in soil samples from a skate park, a clinic, and a residential area. Authorities have already taken steps to address the issue by closing down four quarries linked to the contamination.

The problem came to light after tests revealed asbestos in multiple locations across Burgenland. While Austria banned asbestos in 1990—followed by an EU-wide prohibition by the late 1990s—traces of the mineral have resurfaced in unexpected places. In recent years, asbestos has even been detected in children's toys, prompting recalls in Austria and beyond.

Air quality checks in the affected areas showed no breach of the Austrian Environment Agency's safety limits for post-remediation conditions. However, indoor exposure above 1,000 fibres per cubic metre still requires urgent action under Austrian and German regulations. The EU is also tightening workplace limits, reducing the allowable exposure to 2,000 fibres per cubic metre over the next four years.

Asbestos, once prized for its fireproof and acid-resistant properties, is now recognised as a severe health hazard. Inhaling its fibres can lead to chronic inflammation and cancer. Over 60 countries, including Brazil, Iran, Taiwan, Ukraine, and the US, have fully banned its use in recent years.

The contaminated crushed rock in Burgenland must now be removed to prevent further risk. With the quarries shut down, authorities aim to eliminate ongoing sources of exposure. The situation highlights the lingering dangers of asbestos, despite decades-old bans in Europe.
