[Abstract]

　In order to fully understand the acidification of precipitation, it is essential to determine ammonia emissions. Detailed gridded NH₃ emission fluxes have been compiled for Europe. In East Asia they have been determined on a national basis. We have calculated NH₃ emission fluxes from livestock and ferilizer applications in Japan and Korea on a 1゜latitude×1゜ longitude basis. The maximum calculated NH₃ emission fluxes for each of the 4 animal categories were 4740, 4740, 4600, and 5180 tonnes NH₃/grid/y from pigs in the central part of Korea, in the central part of Korea, dairy cows in the eastern part of Hokkaido, beef cattle in the central part of Korea, and poultry in the southern part of Kyushu, respectively. The total NH₃ emissions from livestock in Japan and Korea were 4.41, 4.61, 6.02, and 7.77×10⁴ tonnes NH₃/y and 2.41, 1.15, 3.71, and 1.92×10⁴ tonnes NH₃/y from pigs, dairy cows, beef cattle, and poultry, respectively. The overall total NH₃ emissions from livestock and fertilizer applications in Japan and Korea were 27.8×10⁴ and 14.4×10⁴ tonnes NH₃/y, respectively.
