The Helsinki metropolitan area is experiencing high street dust concentrations, particularly along busy roads, leading to poor air quality.

During rush hour, dust levels can exceed normal by over ten times.

Nelli Kaski, an air quality expert at HSY, advises in a news release to avoid heavy traffic areas when outdoors, as cleaner air is found just one block away from congested streets.

Sunny, dry weather increases dust levels, while rain provides temporary relief.

Symptoms from street dust, such as cough and irritation, can affect anyone but are especially harmful to those with respiratory or heart issues, the elderly and young children.

To alleviate symptoms, it’s recommended to choose routes away from busy streets.

Tips for minimizing exposure to street dust while outdoors

Here are several strategies to help reduce your exposure to street dust when spending time outside:

  • Select routes that are a bit further from busy main roads.
  • Prefer green spaces and quieter side streets whenever possible.
  • Avoid going outdoors on dry, windless days, as dust levels tend to be higher during these times.
  • At bus stops, position yourself as far from the road as you can or find a sheltered area.
  • If needed, consider wearing an FFP2 respirator (high-efficiency respirator) if you are in a risk group or are susceptible to symptoms.
