Emission Inventory of Volatile Organic Compounds from Field Burning of Crop Residues in Hubei Province, China

Abstract:

Crop residues combustion is an important anthropogenic sources of volatile organic compounds (VOCs) in China.Emissions of VOCs from crop residues combustion significantly affect climate forcing and human health. A reliable estimation of VOCs emission from the source is the important prerequisite for emission impact assessment and control strategy in the urban or regional areas. VOCs emissions from crop residues combustion in Hubei Province, China and the districts were estimated by factor analysis method, which was based on the yield of major farm crops in the period of 2010. Moreover, Cultivated-land emission intensity (I_c) and Regional emission intensity (I_r) were also calculated. VOCs Emissions from crop residues combustion in Hubei Province were about 80, 000 t in 2010; I_c and I_r were 2.431 t•km^-2 and 0.434 t•km^-2 respectively; Huanggang, Jingzhou, Xiangyang, Jingmen and Xiaogan had the top five of VOCs Emissions from crop residues combustion. I_c and I_r of Qianjiang, Xiaotao and Ezhou were all more than the average; I_c of Suizhou and I_r of Tianmen were also above the average. 10 city mentioned above should be draw attention as the priority control area. Furthermore, crop residues utilization according to agricultural cyclic economy is a feasible way to cope with the environmental problem of biomass combustion.
