“…Further, good ventilation may have a similar mechanism for reducing the risk of hyperactivity in children. For instance, a recent experimental study demonstrated that the wind speed of the kitchen ventilator directly affected the level of PM concentration during the cooking process, and that the concentration of PM could be decreased by over 65 percent at high wind speed when compared to medium wind speed . These results provide some support for our findings, but more research is needed to verify these findings and to identify more clearly and comprehensively the potential mechanisms.…”

Cooking is one of the main sources of indoor air pollution in China. Given emerging evidence of a link between air pollutants and neurodevelopmental delays, we examined whether maternal experiences with cooking during gestation might increase their child's hyperactivity at 3 years of age. The participants involved 45 518 mothers of children who were newly enrolled at kindergarten in the Longhua District of Shenzhen from 2015 to 2017. The results show that maternal exposure to cooking fumes during pregnancy was related to an increased risk of their offspring having hyperactivity behaviors at the age of 3 years. Compared with pregnant mothers who never cooked, pregnant mothers who cooked sometimes, often, or always had children who showed a significantly higher hyperactivity risk. Households using cooking fuels such as coal, gas during the mothers’ pregnancy, exhibited more hyperactivity behaviors in the young child when compared to those using electricity for cooking. In addition, poor ventilation during cooking, while mothers were pregnant, was found to be a significant risk factor for clinical levels of the offspring's hyperactive behaviors. Furthermore, the positive association with maternal cooking during pregnancy and their offsprings’ hyperactivity was relatively consistent across strata defined by social class, education, and other covariates.

“…The average number and mass concentration of PM2.5 in Chinese kitchens were found to increase by more than ten times during cooking in comparison with non-cooking hours (Gao et al 2013;See and Balasubramanian 2006b). Epidemiological results demonstrated a significant link between negative health effects and exposure to particulate matter from cooking (Lu et al 2019;Metayer et al 2002;Pope III 2000;Sze-To et al 2012;Wang et al 2017). The range hoods used in present Chinese homes and restaurants discharge cooking fumes to the outdoor environment without a disposal process, resulting in severe haze (Zhu et al 2014).…”

Chinese cooking produces large numbers of particles that can cause both indoor and outdoor air quality problems. To reduce the extraction of particles to the outdoor air, this investigation studied capture efficiency of a rotating disk in an exhaust hood. The studies were performed experimentally in a wind tunnel and numerically by computational fluid dynamics (CFD) models with the Lagrangian method for tracking particle trajectories. The experimental data were used to identify the best turbulence model among the three tested in the CFD simulations. The results show that the capture efficiency increased with disk rotation speed and particle size but decreased with exhaust airflow rate. The CFD simulations provided detailed information about the mechanisms by which particles of different sizes were captured by the rotating disk. CFD was then used to explore two methods for improving the capture efficiency: adding more wires to the middle and outer zones of the disk, and using two layers of disks. Both methods can increase the capture efficiency of the rotating disk at an acceptable pressure loss.

“…Burning of fossil fuels (like oil, gasoline and coal) is the one of the major sources that is responsible for air pollution and environmental dilapidation [4], [5], which releases smoke related particulate matter, unburnt hydrocarbons, oxides of nitrogen and sulfur, at the same time a significant amount of carbon dioxide is also released, which will intensifies the green house effects. The health problems that we are facing due to air pollution are acute lower respiratory illness, lung cancer, distortion, cerebrovascular disease(stroke), chronic obstructive pulmonary disease, mutation of human body Ischemic heart disease, and mortality in adults [6], [7].…”

Increasing demand of the carbon fuels in daily life and the global environmental degradation has led to the biodiesel production from non-edible oils because they has high potential as ecological, clean, facile and renewable fuel. In present study, oil is extracted from dried Eruca sativa seeds using mechanical expellers, the oil yield obtained is calculated. By alkaline transesterification, the obtained oil is converted into biodiesel. The physicochemical properties of Eruca sativa biodiesel are tested following ASTM test methods, all the properties satisfies and meet the ASTM D-6751 biodiesel standard specifications. The gas chromatography technique is used for the analysis of fatty acid composition of the biodiesel, which shows that the erucic acid has higher percentage composition. Emission characteristics (i.e. carbon monoxide, carbon dioxide, hydro carbon, nitrogen oxide and smoke) of diesel engine are analyzed for the biodiesel and its blends (i.e. B10, B20, B30, B40 and B100) and are compared with the petroleum diesel. From the emission results obtained it is observed that, the CO and CO2 emissions are lower for B10 and B20 blends whereas the HC emissions are lesser than diesel for all the blends. For B10, B20 and B30 blends the NOX emission and smoke opacity has been reduced when compared to diesel.
