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

The characterisation of particulate pollution in an airport environment: Manchester international airport, UK, a case study
TL;DR: In this paper, the authors used magnetic measurements, geochemical analysis, SEM/EDX and ESR to identify characteristic "fingerprints" of primary particulates derived from key sources in an airport environment.
Guidelines for optimal partially premixed combustion operation
TL;DR: In this paper, the influence of two important fuel properties (cetane number and aromaticity) on soot emissions is investigated independently of one another, and the main conclusions illustrate that the effects are quite different for conventional combustion (i.e., diffusion or hot combustion) and the partially premixed combustion (cold combustion) variant.

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.
