Air pollution (AP) is one of the major causes of health risks as it leads to widespread morbidity and mortality each year. Its environmental impacts include acid rains, reduced visibility, but more importantly and significantly, it affects human health. The price tag of not managing AP is seen in the rise of chronic obstructive pulmonary disease (COPD), cardiovascular disease, and respiratory ailments like asthma and chronic bronchitis. But as the world battles the corona pandemic, COVID-19 lockdown has abruptly halted human activity, leading to a significant reduction in AP levels. The effect of this reduction is captured by reduced cases of morbidity and mortality associated with air pollution. The current study aims to monetarily quantify the decline in health impacts due to reduced AP levels under lockdown scenario, as against business as usual, for four cities-Delhi, London, Paris, and Wuhan. The exposure assessment with respect to pollutants like particulate matter (PM 2.5 and PM 10 ), NO 2 , and SO 2 are evaluated. Value of statistical life (VSL), cost of illness (CoI), and per capita income (PCI) for disability-adjusted life years (DALY) are used to monetize the health impacts for the year 2019 and 2020, considering the respective period of COVID-19 lockdown of four cities. The preventive benefits related to reduced AP due to lockdown is evaluated in comparison to economic damage sustained by these four cities. This helps in understanding the magnitude of actual damage and brings out a more holistic picture of the damages related to lockdown.

“…The anthropogenic activities are a major cause of ambient air pollution due to emission of many harmful pollutants in high concentration, which are health damaging (Gautam and Hens 2020a ; Ghorani-Azam et al 2016 ). Similarly, indoor air pollution is on the rise due to factors contributed by activities related to the use of the traditional ill-designed cook stove, refrigerators, biomass burning, poor ventilation, and surroundings (Gautam and Trivedi 2020 ; Nair et al, 2020 ; Gupta et al, 2020 ). Due to exposure of high air pollution concentrations, people are facing severe health effects.…”

The present work estimates the increased risk of coronavirus disease (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 by establishing the linkage between the mortality rate in the infected cases and the air pollution, specifically Particulate Matters (PM) with aerodynamic diameters ≤ 10 µm and ≤ 2.5 µm. Data related to nine Asian cities are analyzed using statistical approaches, including the analysis of variance and regression model. The present work suggests that there exists a positive correlation between the level of air pollution of a region and the lethality related to COVID-19, indicating air pollution to be an elemental and concealed factor in aggravating the global burden of deaths related to COVID-19. Past exposures to high level of PM 2.5 over a long period, is found to significantly correlate with present COVID-19 mortality per unit reported cases (p < 0.05) compared to PM 10 , with non-significant correlation (p = 0.118). The finding of the study can help government agencies, health ministries and policymakers globally to take proactive steps by promoting immunity-boosting supplements and appropriate masks to reduce the risks associated with COVID-19 in highly polluted areas.

“…The cookstove power, some of its components, and the stove yield were finally computed, using the standards NF EN 16510 [5]. Differences between the values of these parameters and physical quantities obtained in the present study appear with that of the literature, see [6,10,14,20,31,32], and [33], for example, see also the review [11] and the references in these papers. These differences may be explained by differences in the conception of the cookstove, its draught, and in the combustibles which are used for the experimental tests.…”

“…In [9], the specific consumption of three improved cookstoves were measured between 169 and 261 g.L −1 . The specific fuel consumption was evaluated in [14] at 85 g.L −1 for a coal start water ebullition test in different biomass cookstove. The CO concentrations were measured between 7 and 20 ppm and the thermal efficiency (2021) 3:652 | https://doi.org/10.1007/s42452-021-04630-4…”

Analysis and modeling of the thermal behavior of an improved pellet cookstove

In Sub-Saharan countries, cooking is usually done at a domestic scale using rudimentary stoves with wood or charcoal as combustibles. To improve the cooking behavior and reduce the deforestation, an improved pellet cookstove was conceptualized with guiding ideas in mind such as simplicity, robustness and ability to burn pellets built with local wood residues under a natural draught. Combustion and water ebullition tests were performed with two configurations of the upper part of the cookstove: thick steel plate or ring, and with standardized EN+ pellets as combustible. The main pollutant gases (CO, CO2 and NOx), together with O2, were continuously measured at different positions of the cookstove during a water ebullition test with the ring configuration. The levels measured above the pot were lower than the thresholds currently proposed by the World Health Organization. Simple and phenomenological thermal models were proposed to simulate the plate, or ring, and water temperatures during the combustion or water ebullition tests and to determine the intrinsic convection coefficients. The maximal relative differences between the experimental and simulated temperatures were computed between 7 and 21%. The stove power was evaluated at 4336 ± 23 W. The cookstove yield for the water ebullition test with the ring configuration was computed equal to 12.3 ± 0.1%, slightly lower than that of cookstoves previously analyzed in the literature.
