“…Ambient and indoor PM 2.5 is increasingly becoming one of the major focuses of health-related determinants in Asia and globally [21,22], and our study is one of such that focuses on its health effect in a region that is well known for higher levels of short-term and long-term ambient PM 2.5 exposure [9]. This study explored the relationship between types of ambient PM 2.5 and under-five and maternal deaths and found positive associations with under-five and maternal mortality which was consistent with previous studies [5,7,23,24].…”

The Asian region is one of the major emission sources of air pollution. Although ambient PM2.5 has been linked to several health risks in high-, low-, and middle-income countries, the further analysis of type impact is still rare but significant. The PM2.5 distribution retrieved from MODIS (Moderate Resolution Imaging Spectroradiometer) aerosol optical depth products within 16 years thus explored the associations between under-five and maternal mortality for 45 countries in Asia. Both the nonparametric (Generalized Additive Mixed-Effect) and parametric (Generalized Linear Mixed-Effect) models were employed to analyze the collected datasets. The results show that the levels of PM2.5 in Asian sub-regions were higher than the Global Air Quality Standards. Biomass PM2.5 concentrations was associated with increased the rate of under-five (Incidence Rate Ratio, IRR = 1.29, 95% CI, 1.13–1.47) and maternal (IRR = 1.09, 95% CI: 1.08–1.10) deaths in Asia. Anthropogenic PM2.5 was associated with increased rate of under-five deaths in Asia by 12%. The nonparametric method revealed that dust PM2.5 was positively associated with the under-five (β = 0.04, p < 0.001) and maternal (β = 0.07, p < 0.001) deaths in Asia. The rate of maternal deaths was increased by biomass/dust (IRR = 1.64, 95% CI: 1.63–1.65) and anthropogenic/dust (IRR = 1.22, 95% CI: 1.19–1.26) mixture types. In summary, long-term exposure to different types of ambient PM2.5 in high concentration increased the rate of under-five and maternal deaths, suggesting that policies focusing on preventive and control measures is imperative for developing an improved maternal, newborn, and child health in Asia.

“…With ongoing economic development in East Asia, aerosol emissions release into the atmosphere have risen and exerting a significant influence on the climate (Gui et al, 2019). To understand these trends, further studies about aerosol in Asia are necessary (IPCC, 2013;Balasubramanian et al, 2017). In this work, we use PLDR and SSA at 1020 nm from AERONET standard measurements to classify atmospheric aerosol over five regions in East Asia and Southeast Asia.…”

Utilizing particle linear depolarization ratio (PLDR) and single scatter albedo (SSA) at 1020 nm from AERONET (Aerosol Robotic Network) Version 3 Level 2.0 data, we distinguish seven kinds of aerosol types (including the pure dust, dust-dominated aerosol, pollution-dominated aerosol, non-absorption aerosol, weak absorption aerosol, medium absorption aerosol and strong absorption aerosol) to explore the spatial and temporal distributions of aerosol components, the radiative effect of fine-and coarsemode aerosol. We use observations from stations located in five regions: northern China, northwest Asia, the Tibetan Plateau, southern China and Southeast Asia. Fine-mode aerosol dominates in northern China, while coarse-mode aerosol is prevalent in northwest Asia. Fine-mode aerosol also plays a crucial role in the Tibetan Plateau, southern China and Southeast Asia. The highest radiative forcing efficiency (110.3 W m-2) for fine-mode aerosol in the plateau region is corresponding to high concentrations of strong absorption (SA) aerosol. Lowest radiative forcing and radiate forcing efficiency both appears during summer in southern China. Aerosol components are clearly distinct for the spatial and temporal distributions in Southeast Asia. SA aerosol

“…Few studies identified that burning of Arabian incense in various homes, restaurants, and offices is the main source of indoor air pollution in UAE, as it can emit a wide amount of air pollutants (Balasubramanian et al, 2017;Jetter et al, 2002). Elsayed et al (2016) characterized a complete profiling of Bakhour (an Arabian incense), as a commonly burnt indoor household biomass used in UAE (commonly produced in Sharjah).…”
