Development of agricultural machinery emission inventory of Beijing, Tianjin, and Hebei

In China, with the rapid advancement of agricultural practice, agriculture machineries have become an essential tool. The widely use of agriculture machineries also make them a significant source of air pollutants, including nitrogen oxides (NOx) and particulate matter (PM), because most agricultural machineries are not equipped with an emission treatment system and some are poorly maintained. This study will develop an agricultural machinery air emission inventory of Beijing, Tianjin, and Hebei; this region often experiences the worst air quality in China. Survey questionnaires will be used to collect inventory and usage data of agriculture machineries. Emission factors will be selected from the literature. An estimation of air emissions in Beijing, Tainjin and Hebei will provide valuable information on the current impact of agricultural machinery on regional air quality and identify direction of improvement. The information collected will help policy makers enforce necessary regulations to improve air quality in the region.
