Every year, almost 2 billion new vehicle tires are produced world-wide. At the same time >1 billion tires reach their end of life. During use, tire wear particles (TWPs) form through abrasion of the rubber material, and in contact with the road surface composites of both materials form tire and road wear particles (TRWPs). These emissions represent a large fraction of total microplastic pollution, and thus a pressing environmental challenge that cannot be counteracted by “green” urbanization through the electrification of car, truck, and airplane fleets. In fact, heavier electric cars may emit even more TWPs and increase the frequency of tire replacements. In addition to TWPs and TRWPs, crumb rubber (CR) produced from end-of-life tires has been a popular low-cost product as infill on artificial grass for outdoor sports pitches, where it has become a substitute for natural grass, sand, or gravel, but is prone to runoff into the surrounding environment.

Particulate Matter Research and Management in Serbia
Clean air is a basic requirement for human health and well-being. According to [1], air pollution is the largest environmental health risk in Europe, with PM being responsible for majority of the adverse effects. The most commonly used metrics for PM is mass for different PM sizes by aerodynamic diameter: inhalable PM includes PM10 for particles equal or smaller than 10 μm, PM2.5 for those equal or smaller than 2.5 μm, and ultrafine particles for those smaller than 100 nm. The smaller the particles are, the deeper they penetrate deep into the lungs and even enter the cardiovascular system, increasing the risks to human health [2]. New ways of characterizing PM, and new understanding of mechanisms of adverse health effects, are emerging.
