“…Currently, cogeneration plants typically use 4 types of energy sources: natural gas, biomass, waste gas, and waste material. For each energy source, previous literature analyzed and reported the potential hazardous emissions: natural gas [30][31][32][33][34] . However, the context of these studies differed from that of the cogeneration plants because these studies focused on sole municipal waste incinerators and not cogeneration plants.…”

Background Combined heat and power generation (CHP generation, also called ‘cogeneration’) is attracting public attention for its high thermal efficiency, without considering possible adverse environmental health effects.This study investigated the potential role of cogeneration plants in inducing 3 environmental diseases: asthma, allergic rhinitis, and atopic dermatitis. Methods From 1 January 2013 to 31 December 2017, the towns (dongs) of South Korea in which a cogeneration plant started operation were selected as study sites. For comparison, a matched control dong with the most similar Gross Regional Domestic Product for each case dong was selected. The numbers of outpatient visits, inpatient admissions, and emergency visits provided by the National Health Insurance Sharing Service (NHISS) were analyzed using an interrupted time-series design. For air pollutants, the concentrations of 5 air pollutants from the AIRKOREA dataset were used. Results A total of 6 cogeneration plants in 6 case dongs started operation during the study period. For overall case dongs, the pre-CHP trend was 1.04 (95% confidence interval [CI]: 1.038–1.042), and the post-CHP trend was 1.248 (95% CI: 1.244–1.253). The intercept change due to the CHP plant was 1.15 (95% CI: 1.137–1.162). For overall control dongs, the pre-CHP trend was 1.133 (95% CI: 1.132–1.135), and the post-CHP trend was 1.065 (95% CI: 1.06–1.069). The intercept change due to the CHP plant was 0.888 (95% CI: 0.878–0.899). Only for CO and NO 2 , the relative risk (RR) for overall case dongs was statistically significantly increased, and the RR for the overall control dongs was statistically insignificant. Conclusions Possible hazardous emissions, like CO and NO 2, from cogeneration plants could induce environmental diseases in nearby community populations. The emissions from cogeneration plants should be investigated regularly by a governmental agency, and the long-term health outcomes of nearby community residents should be investigated.

“… Gao et al (2009) concluded that the PB events measured during their study resulted from local power plant plumes. On-site measurements at natural gas burning plants observed 2–7 nm sized particles in concentrations ranging from 1.27 × 10 5 to 1.7 × 10 7 cm −3 ( Bond et al, 2006 ; Brewer et al, 2016 ; Shi et al, 2001 ).…”

“…The mode diameter of the airport size distributions range between 11 and 16 nm, meaning nearly half of the distribution is less than 10 nm in diameter ( Brilke et al, 2020 ; Ren et al, 2016 ; Zhu et al, 2011 ). Natural gas burning combustion plants also emit a significant number of particles between 2 and 7 nm ( Brewer et al, 2016 ; Shi et al, 2001 ). The mean diameter of particles emitted by power plants is approximately 5 nm and increases with decreasing energy load ( Bond et al, 2006 ).…”

Ultrafine particles with diameters less than 100 nm suspended in the air are a topic of interest in air quality and climate sciences. Sub-10 nm particles are of additional interest due to their health effects and contribution to particle growth processes. Ambient measurements were carried out at North Carolina State University in Raleigh, NC between April to June 2019 and November 2019 to May 2020 to investigate the temporal variability of size distribution and number concentration of ultrafine particles. A mobile lab was deployed between March and May 2020 to characterize the spatial distribution of sub-10 nm particle number concentration. New particle formation and growth events were observed regularly. Also observed were direct emissions of sub-10 nm particles. Analysis against meteorological variables, gas-phase species, and particle concentrations show that the sub-10nm particles dominated number concentration during periods of low planetary boundary layer height, low solar radiation, and northeast winds. The spatial patterns observed during mobile deployments suggest that multiple temporally stable and spatially confined point sources of sub-10 nm particles are present within the city. These sources likely include the campus utility plants and the Raleigh-Durham International Airport. Additionally, the timing of data collection allowed for investigation of variations in the urban aerosol number size distribution due to reduced economic activity during the COVID-19 pandemic.

“…PM is mainly generated by the combustion of fossil fuels such as natural gas and diesel fuel (i.e., automobile fuel, heating, industry) (Holmén and Ayala 2002;Murphy et al 2009;Rogge et al 1993;Xue et al 2018). It is comprised of metallic elements (As, Be, Ca, Cd, Co, Cr, Fe, K, Mn, Ni, Pb, Sb, Se, Zn) (Park and Dam 2008), carbon sources (Adams et al 2015;Funasaka et al 2000), and inorganic compounds such as sulfate, nitrate, halide, and ammonium (Borgie et al 2015;Brewer et al 2015). Among them, carbon and sulfur sources are found to be highly correlated with cardiovascular diseases (Adams et al 2015;Brook 2008;Lee et al 2005).…”

Electron microscopic and spectroscopic analysis of airborne ultrafine particles: its effects on the cell viability

Particulate matter (PM) is one of the most common air pollution sources causing various health-related conditions like cardiovascular diseases. However, among the three major PM types, UFPs have not yet been independently studied for their toxic effects on human health. In this study, we collected airborne dusts from Chuncheon-si, Republic of Korea, and analyzed it to understand the structural and chemical features of UFPs by using transmission electron microscope (TEM), energy-dispersive X-ray spectroscopy (EDX), and X-ray photoelectron spectroscopy (XPS). The TEM result showed UFP size to be within 100 nm, with some even appearing about 10 nm in size, while the Xray spectroscopic studies implied the presence of sulfur to be a part of the UFPs chemical composition. We extended our study by carrying out in vitro cell analysis to understand the cellular response upon UFPs treatment. Our results serve as an analytical platform providing the preliminary information about the structural and compositional aspects of UFPs that can be attributed to further understanding of sulfur-induced human diseases.
