The increased occurrence of serious health effects, mortality and morbidity as well as shortened life expectancy have been related to exposure to ambient air pollution. Air quality policies, such as the definition of air quality standards, vary greatly among countries and these regulatory discrepancies amplify the differences in air quality and related health effects around the globe. To reduce air pollution and improve air quality, robust, evidence-based and effective environmental policies are needed. The thorough study of the pollutants’ sources and emissions, of the population exposure and of the exposure-related impacts on health represents the basis for the development of air quality policies and the assessment of their effectiveness.
This Special Issue aims to present original research articles, reviews, and short communications concerning the following: (1) the sources and emissions of air pollutants, (2) the resulting exposure of the general population or of specific categories of subjects, (3) in different environments, including indoor environments, and (4) the potential health impacts that may result from it. The important role of environmental policy in mitigating these impacts should also be emphasized, as well as the potential for relevant benefits related to efforts in reducing pollutants emissions, enhancing air quality and reducing population exposure.

Title: Occupational fine/ultrafine particles and noise exposure in aircraft personnel operating in airport taxiway

Abstract: The occupational exposure to airborne fine and ultrafine particles and noise in aircraft personnel employed in airport taxiway was investigated. Multiple sampling sites and job tasks were considered: i) personal samplings (n.34) of Aircraft Ground Equipment personnel (AGE), firefighting officers, flight security agents, aviation fuel’s administration staff (AFS), ii) stationary background receptor site, iii) close to the airstrip. Particle number, surface area concentrations and distributions were measured by personal particle counters (Diffusion Size Classifier DiSCmini and Sioutas Cascade Impactor) and by means of an electric low pressure impactor (ELPI). Chemical analyses were performed by TEM and SEM + EDX analyses. A-weighted noise exposure level (LAeq), A-weighted noise exposure level normalized to an 8 h working day (LAeq8hr) and Peak Sound C-weighted Pressure Level (LC peak) was calculated for single worker and for homogeneous exposure groups. AFS showed highest exposure level considering both concentration (median 6.7x103 part/cm3 IQR 4207 – 12531) and lung surface deposition area (median 20.78 µm2/cm3, IQR 13.98 – 32.67) compared with other job tasks with peaks of 1x107 part/cm3. LAeq ranged from 63.8 to 93.7 dBA (mean 79.6, sd 7.4), while LAeq8hr ranged from 54.6 to 91.5 dBA. LC peak maximum level reached 135 dBC (mean 129.7, sd 4.3). Our study provides evidence for the impact of aviation-related emissions on occupational exposure to ultrafine particles and noise exposure of workers operating in airport taxiway. Main exposure peaks are related to pre-flight operations of engine aircrafts. Although exposure to UFP and noise appears to be not critical if compared with other occupational scenarios, the coincidence in time of high peaks of exposure to UFP and noise suggest that further investigations are warranted in order to assess possible subclinical and clinical adverse health effects in exposed workers, especially for cardiovascular apparatus.
Title: Distribution characteristics and influence of OC and EC in fine particulate matter (PM2.5) in Changchun city

Abstract: In recent years, the air quality in Changchun city has been declining year by year, and the haze events are frequent, which has negative impacts on life and human health, and its research has attracted much attention. At present, fine particulate matter (PM2.5) has become the primary pollutant in China's urban atmosphere and has a significant impact on air quality and visibility. Organic carbon (OC) and elemental carbon (EC), the main components of PM2.5, have also received widespread attention. In order to understand the law of the change of OC and EC in Changchun PM2.5, the PM2.5 samples in Changchun were collected from April to December in 2017 using the KC-120H particulate matter sampler, and the OC/EC analysis was conducted using NIOSH 5040 method to determine the concentration of OC and EC in PM2.5 in Changchun. According to the results of the CMB model of PM2.5 in Changchun city in 2017 and relevant literature, this paper calculated the contribution rate of different pollution sources to OC and EC in Changchun city. The results showed that the average concentration of PM2.5 in Changchun city was 45.92 μg/m3, of which the annual average concentration of OC and EC ranged from 15.69-24.32 μg/m3 and 1.38-2.33 μg/m3. OC and EC concentrations were 21.70 and 1.85 μg/m3 respectively. The annual OC/EC ratio range was 8.08-15.44 and the average value was 11.70, indicating that the main sources of EC and OC in Changchun city were coal burning and ground dust, and there was organic carbon generated by secondary reaction. The average concentration of OC in Changchun city is 21.7. The annual average concentration of EC in Changchun city was 1.85 μg/m3, accounting for 4.48% of PM2.5 concentration. The results showed that the sources of OC and EC in the PM2.5 of Changchun city could be an important index for the determination of atmospheric particulate pollution, and fine particulate matter was also one of the main factors causing cardiovascular system diseases.

Title: Analysis of spatial-temporal variation of surface O3 concentrations and its associated meteorological factors in Changchun

Abstract: Ozone (O3) pollution has become one of the most challenging problems in China, high O3 concentrations have been a major air quality issue in Changchun. Based on continuous observation data of surface ozone concentrations from 10 automatic air monitoring stations and meteorological data from meteorological bureau in Changchun, temporal and spatial variations of O3 concentration and its relationships with meteorological factors were analyzed by both related analysis and cluster analysis during the period 2013-2017. The results showed that an increasing trend of the annual mean O3 concentrations of daily maximum 8h average (MDA8) was found from 2013 to 2016 in Changchun and the O3 pollution was increasing year by year. The concentrations of MDA8 of O3 declined slightly in 2017, probably due to cloudy, rainy, high relative humidity and low temperature weather conditions in Changchun during May to August 2017. The O3 concentrations in suburban area was higher than that in downtown. The seasonal variation of O3 concentrations in Changchun was obvious, spring > summer > autumn >winter, and the days of O3 concentrations exceeding the standard were concentrated in spring and summer, which is different from the results of neighboring cities and provinces of Changchun. It is speculated that it may be due to the low thickness of the mixed layer in spring. The over-standard time of O3 concentrations in Changchun mainly appeared in April to July, and its monthly mean value curve showed a bimodal type in which highest O3 concentration appeared in May and July, whereas the lowest appeared in December. The diurnal pattern of ozone showed a single peak mode, and the peak value usually appeared at 14:00 to 16:00. Higher temperature is a necessary condition for ozone pollution in Changchun. When the temperature is higher than 20℃, O3 concentrations increased significantly. O3 concentrations was negatively correlated with relative humidity and atmospheric mixing layer thickness. When the relative humidity was higher than 70% and atmospheric mixing layer thickness was higher than 800 meters, O3 concentrations in Changchun decreased significantly. The O3 concentrations was highest when the wind speed approaches 1-2 m/s and the wind direction is WSW, combined with the simulation results of the backward trajectory model, it is indicated that there may be an O3 contribution from the west side of Changchun.
