Abstract

Intensive animal farms emit large amounts of ammonia (NH3) into the atmosphere. NH3 can cause the formation of NH4+ particles in the atmosphere and their return to the land surface via NH3/NH4+ deposition, imposing the risks of particulate matter and reactive nitrogen (Nr) pollution. Here, we investigated NH3 emissions from an intensive dairy farm, atmospheric NH3/NH4+ deposition, and PM2.5 concentration in the vicinity of the dairy farm in central South China, with the aim of determining the effects of high NH3 emissions from dairy farms on atmospheric N deposition and aerosol pollution. NH3 deposition at a distance of 500 m from the edge of the dairy farm accounted for 10.2 % of annual NH3 emissions from the dairy farm. The measured annual PM2.5 concentration at the dairy farm showed 1.8 times higher than that reported at the neighboring city sites, with aerosol NH4+ contributing to a large part of PM2.5. Total N deposition within 500 m of the dairy farm was as high as 78.4 kg N ha−1 yr−1 (NH3/NH4+ deposition accounting for 64.4 %), which was 2.1 times higher than the N deposition in the neighboring region without dairy farms. Our study indicates that intensive animal farms cause high N deposition and severe airborne particulate matter pollution, and it is important to mitigate NH3 emissions from intensive dairy farms.

期刊介绍: Agriculture, Ecosystems and Environment publishes scientific articles dealing with the interface between agroecosystems and the natural environment, specifically how agriculture influences the environment and how changes in that environment impact agroecosystems. Preference is given to papers from experimental and observational research at the field, system or landscape level, from studies that enhance our understanding of processes using data-based biophysical modelling, and papers that bridge scientific disciplines and integrate knowledge. All papers should be placed in an international or wide comparative context.
