“…The average PM 2.5 concentrations of cookstove smoke varied between 1.5 and 9.5 mg/m 3 for inside compared to 0.7 and 3 mg/m 3 for outside; whereas the average BC concentration of cookstove smoke was observed to be in the range of 0.5 to 1.6 mg/m 3 for inside compared to 0.3 to 0.5 mg/m 3 for outside. Our observed concentration range aligns with the results of other field studies on indoor exposure or cookstove emission [38,39,62,63].…”

“…However, the past several studies conducted in real households were also limited by the sample size and have explained in detail about the sampling difficulties. The sampling number in those studies conducted in various countries varies from as low as two to less than fifteen [39,40,63,64] suggesting the acceptance of smaller sample size for emission measurement studies. Moreover, the empirical relationship between the emission factors and the ambient pollutant concentration were not derived in the present study.…”

Residential emission from traditional biomass cookstoves is a major source of indoor and outdoor air pollution in developing countries. However, exact quantification of the contribution of biomass cookstove emissions to outdoor air is still lacking. In order to address this gap, we designed a field study to estimate the emission factors of PM2.5 (particulate matter of less than 2.5 µ diameter) and BC (black carbon) indoors, from cookstove smoke using biomass fuel and with smoke escaping outdoors from the roof of the house. The field study was conducted in four randomly selected households in two rural locations of southern Nepal during April 2017. In addition, real-time measurement of ambient PM2.5 was performed for 20 days during the campaign in those two rural sites and one background location to quantify the contribution of cooking-related emissions to the ambient PM2.5. Emission factor estimates indicate that 66% of PM2.5 and 80% of BC emissions from biomass cookstoves directly escape into ambient air. During the cooking period, ambient PM2.5 concentrations in the rural sites were observed to be 37% higher than in the nearby background location. Based on the World Health Organization (WHO)’s AirQ+ model simulation, this 37% rise in ambient PM2.5 during cooking hours can lead to approximately 82 cases of annual premature deaths among the rural population of Chitwan district.

“…For instance, disease that can relate to respiratory system problem is tuberculosis (TB) (Huang et al, 2020). Except for outdoor air pollution as researched by Anderson et al (2012), indoor air pollution event can also resulted into the same health problem (De la Sota et al, 2018). Air pollution event not only has impact on human health but also on animal life and environment where the animals will experience reproductive problem and in some serious cases, it will extinct.…”

Abstract. Degradation of air quality level can affect human’s health especially respiratory and circulatory system. This is because the harmful particles will penetrate into human’s body through exposure to surrounding. The existence of air pollution event is one of the causes for air quality to be low in affected urban area. To monitor this event, a proper management of urban air quality is required to solve and reduce the impact on human and environment. One of the ways to manage urban air quality is by modelling ambient air pollutants. So, this paper reviews three modelling tools which are AERMOD, CALPUFF and CFD in order to visualise the air pollutants in urban area. These three tools have its own capability in modelling the air quality. AERMOD is better to be used in short range dispersion model while CALPUFF is for wide range of dispersion model. Somehow, it is different for CFD model as this model can be used in wide range of application such as air ventilation in clothing and not specifically for air quality modelling only. Because of this, AERMOD and CALPUFF model can be classified in air quality modelling tools group whereas CFD modelling tool is classified into different group namely a non-specific modelling tool group which can be implemented in many fields of study. Earlier air quality researches produced results in two-dimensional (2D) visualization. But there are several of disadvantages for this technique. It cannot provide height information and exact location of pollutants in three-dimensional (3D) as perceived in real world. Moreover, it cannot show a good representation of wind movement throughout the study area. To overcome this problem, the 3D visualization needs to be implemented in the urban air quality study. Thus, this paper intended to give a better understanding on modeling tools with the visualization technique used for the result of performed research.

Cooking has become a challenge in areas where the energy access is limited and the single available fuel is wood. Day by day, more people have been reported with respiratory diseases, caused mainly by the smoke that emits carbon monoxide (CO), particular matters (PM) and other highly harmful compounds resulting from the poor combustion generated on the simplest stoves those using fuel wood. Hence an efficient, hot burning Rocket Stove has been deployed with fabric filters in the earlier days. However, the rocket stoves with fabric filter removes the PM content that is also in small amount mean while considering CO, CO2 and other toxics remains same in the emitted gas/smoke. To tackle with these pollution issues, our proposed work innovates a Bi-folded Colander Framework, which combines a Knapsack filter and simulated Carbon with Cellulose Nano fiber filter to purify the exhaust gas/smoke. It is highly sensitive to filter the nano particles as well the toxic compounds exist in the exhaust smoke. Thus our proposed methodology effectively reduces the pollutions with our novel framework and enhances the fuel efficiency of the rocket stove.
