ABSTRACT
Ammonia emissions include anthropogenic and natural sources. Ammonia emissions from anthropogenic sources were increasingly serious, among which the ammonia emissions from livestock were the largest source and caused the most negative impact increasingly. Hunan province is a big producer of livestock and poultry breeding in China because of its breeding scale. It is in the forefront of China with regard to livestock breeding, which leads to more serious ammonia emission pollution. Obviously the characteristics of ammonia distribution influences the prevention and control of atmospheric pollution, provided the basic data on the fine particulate matter source spectra is available. Therefore, the main goal of the present study was to investigate the distribution of ammonia emission from livestock and poultry breeding in Hunan province in 2004-2014.
