TLDR
The aim of the present literature review study is to present the state-of-the-art of the different aspects regarding PM resulting from brake wear and provide all the necessary information in terms of importance, physicochemical characteristics, emission factors and possible health effects.Abstract:
Traffic-related sources have been recognized as a significant contributor of particulate matter particularly within major cities. Exhaust and non-exhaust traffic-related sources are estimated to contribute almost equally to traffic-related PM10 emissions. Non-exhaust particles can be generated either from non-exhaust sources such as brake, tyre, clutch and road surface wear or already exist in the form of deposited material at the roadside and become resuspended due to traffic-induced turbulence. Among non-exhaust sources, brake wear can be a significant particulate matter (PM) contributor, particularly within areas with high traffic density and braking frequency. Studies mention that in urban environments, brake wear can contribute up to 55 % by mass to total non-exhaust traffic-related PM10 emissions and up to 21 % by mass to total traffic-related PM10 emissions, while in freeways, this contribution is lower due to lower braking frequency. As exhaust emissions control become stricter, relative contributions of non-exhaust sources—and therefore brake wear—to traffic-related emissions will become more significant and will raise discussions on possible regulatory needs. The aim of the present literature review study is to present the state-of-the-art of the different aspects regarding PM resulting from brake wear and provide all the necessary information in terms of importance, physicochemical characteristics, emission factors and possible health effects.read more

TL;DR: In this paper, the authors investigated the relationship between airborne particulate exposure and negative impacts on human health, focusing on the heavy metal content alone might not be sufficient and proposed a novel perspective in the field of urban airborne particle investigation that is not currently found in the literature.

TL;DR: In this article, the influence of volcanic emissions on the composition of nanoparticles and ultrafine road dust was identified in an urban area of the Andes, and the road dust load (RD10) ranged between 0.8 and 26.8 mg m-2 in the city.

Characteristics and sources of PM2.5 and reactive gases near roadways in two metropolitan areas in Canada

TL;DR: In this article, the authors investigated the air quality characteristics and potential sources influencing levels of PM and its chemical composition in Toronto and Vancouver, and found that the influence of traffic-related emissions on air pollution near roads depends more on the proportion of large trucks in the fleet than the total traffic volume.

Sources and properties of non-exhaust particulate matter from road traffic: a review.
TL;DR: It is concluded that with the exception of brake dust particles which may be identified from their copper (Cu) and antimony (Sb) content, unequivocal identification of particles from other sources is likely to prove extremely difficult, either because of the lack of suitable tracer elements or compounds, or of the interactions between sources prior to the emission process.
