Abstract

The importance of ammonia (NH₃) in the atmosphere and its role in acidification is increasingly recognized. A detailed emission inventory of NH₃ for South Korea is carried out for different sources using emission factors. Results indicate that the emission of ammonia has increased by 21% over the last 11 yr from 143 000 t yr^-1 in 1988 to 181 000 t yr^-1 in 1998. The major contributors to the NH₃ emission in South Korea are livestock and fertilizer application that account for 70 and 26% of total NH₃ emission, respectively. The 11 × 14 km (0.125° long. × 0.125° lat.) grid distribution of emission of ammonia shows an maximum in the Yochon area due to the largest fertilizer factory and relatively wide regions of high NH₃ emission in the northwestern part of South Korea due to a great number of livestock. It is found that the nitrogen ratio of wet deposition of NH₄⁺ to emission of NH₃ in South Korea is averaged to be 0.45.
