Däckslitagepartiklar

Däckslitagepartiklar, often referred to as tire wear particles (TWPs), are microscopic fragments shed from vehicle tires during normal operation. These particles are a significant source of non-exhaust particulate matter pollution. As tires come into contact with road surfaces, friction causes small pieces of the rubber and other tire materials to break off and become airborne or deposited on the road. The composition of these particles varies but typically includes rubber polymers, reinforcing fillers like carbon black, and various additives.

The release of däckslitagepartiklar is a continuous process influenced by factors such as driving style, tire pressure, tread depth, road surface characteristics, and vehicle weight. They are not only a concern for air quality but also contribute to microplastic pollution in the environment, as they can be washed into waterways. Research into the environmental and health impacts of TWPs is ongoing, with studies investigating their potential to enter the food chain and affect ecosystems. Mitigation strategies are being explored, including the development of more durable tire materials, improved road surface designs, and advanced filtration systems for vehicle emissions, although TWPs are not technically exhaust emissions.
