“…Particle deposition and inhalation rate through respiratory tracts are estimated using algebraic and semi-empirical deposition models (Hofmann, 2011). We adopted a deposition fraction (DF) model (ICRP, 1994) of the International Commission on Radiological Protection (ICRP) since it is a commonly used approach by researchers (Keast et al, 2022;Martins et al, 2015b) and in our previously published work (e.g. Abhijith and Kumar, 2021;Kumar et al, 2018;Kumar and Goel, 2016).…”

Prior studies have shown that people of color (POC) in the United States are exposed to higher levels of pollution than non-Hispanic White people. We show that the city of Denver, Colorado, displays similar race-and ethnicity-based air pollution disparities by using a combination of high-resolution satellite data, air pollution modeling, historical demographic information, and areal apportionment techniques. TROPOMI NO 2 columns and modeled PM 2.5 concentrations from 2019 are higher in communities subject to redlining. We calculated and compared Spearman coefficients for pollutants and race at the census tract level for every city that underwent redlining to contextualize the disparities in Denver. We find that the location of polluting infrastructure leads to higher populations of POC living near point sources, including 40% higher Hispanic and Latino populations. This influences pollution distribution, with annual average PM 2.5 surface concentrations of 6.5 μg m −3 in census tracts with 0−5% Hispanic and Latino populations and 7.5 μg m −3 in census tracts with 60−65% Hispanic and Latino populations. Traffic analysis and emission inventory data show that POC are more likely to live near busy highways. Unequal spatial distribution of pollution sources and POC have allowed for pollution disparities to persist despite attempts by the city to rectify them. Finally, we identify the core causes of the pollution disparities to provide direction for remediation.

“…Respiration deposition dosage (RDD) is estimated by using the International commission on radiological protection (ICRP) 1994 model (He and Gao, 2021;Keast et al, 2022;Hinds and Zhu, 2022). We estimated operators' respiratory deposition doses (RDD) of PM (PM1, PM2.…”

As a part of their occupation, the operators of heavy earth moving machineries (HEMM) working in opencast mines are exposed to several air pollutants, prominent one being the airborne particulate matter. The paper presents the findings from a study that was aimed at investigating the particulate matter exposure of heavy earth moving machineries (HEMM’s) operators in highly mechanized opencast mines. The HEMMs included in the study are dumper, shovel and drill. The mean in-cabin PM10 concentrations of dumper and shovel, which had an air-conditioning system in the cabin, were in the range of 600–650 µg m− 3. Operators inside the drill cabin that did not have air conditioning systems were exposed to as high as 1992 µg m− 3 However, cabins were effective in preventing up to 20% particulate matter exposure by the operators in comparison to persons working in an open mine atmosphere. The main haul road in mines contributed ~ 50% higher exposure than the internal haul roads. Coarse particles (PM10) are retained in upper respiratory tracts while the fines (PM2.5 and PM1) travel via tracheobronchial region and reach the alveolar region. Occupational exposure of HEMM operators to different pollutants in a mine is at present very limited and therefore more studies need to be conducted.
