Human Health Risk Assessment of Heavy Metals in the Urban Road Dust of Zhengzhou Metropolis, China

open access: yesAtmosphere, 2021
The goal of this research is to assess hazardous heavy metal levels in PM2.5 fractioned road dust in order to quantify the risk of inhalation and potential health effects. To accomplish this, Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) was used

Mass Distribution of Particulate Matter Produced During Abrasion af Asphalt Mixtures in Laboratory

open access: yesCommunications, 2016
Non-exhaust emissions of particulate matter from road traffic can come from abrasion of vehicle parts (tyres, brake linings, clutch and bodywork) or from pavement surface abrasion and also from resuspension of dust. A differentiation between PM emissions

Spatial and temporal variations in Pb concentrations and isotopic composition in road dust, farmland soil and vegetation in proximity to roads since cessation of use of leaded petrol in the UK [PDF]

open access: yes, 2011
Results are presented for a study of spatial distributions and temporal trends in concentrations of lead (Pb) from different sources in soil and vegetation of an arable farm in central Scotland in the decade since the use of leaded petrol was terminated.

Kerb and urban increment of highly time-resolved trace elements in PM10, PM2.5 and PM1.0 winter aerosol in London during ClearfLo 2012 [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
Ambient concentrations of trace elements with 2 h time resolution were measured in PM10–2.5, PM2.5–1.0 and PM1.0–0.3 size ranges at kerbside, urban background and rural sites in London during winter 2012.

Sources and Temporal Variations of Coarse Particulate Matter (PM) in Central Tehran, Iran

open access: yesAtmosphere, 2019
In this study, we used the positive matrix factorization (PMF) model to evaluate the sources of ambient coarse particulate matter (PM) and their temporal variations in two sampling sites, i.e., a school dormitory and a retirement home, located in central

Potential contribution of faeces to resuspended PM1−10 in urban environment

open access: yesAtmospheric Environment: X, 2020
The respirable fraction of resuspended urban road dust contains phosphorous at enhanced concentrations which may imply the potential presence of animal faeces.Specific biomarkers such as faecal sterols and bile acids are commonly used to verify the ...

Re-entrained road dust PM10 emission from selected streets of Krakow and its impact on air quality

open access: yesE3S Web of Conferences, 2018
Scientific research studies conducted in various parts of the world confirm that PM10 concentrations in urban air depend to a great extent on the resuspension processes of the dust deposited on the road surface.
