The biogenic emission of the atmospheric volatile organic compounds (VOCs) from the forests is dominated by monoterpenes. This study investigated the changes in the concentration of monoterpenes distributed in various types of forest near the Gangwon Nature Environment Research Park, Hongcheon, Gangwon Province, Korea. Samples were collected from the three sites of different types of forest, including coniferous, broadleaved and mixed forests. Additionally, the seasonal and daily changes of monoterpene compounds were monitored. Our results found the several types of monoterpene such as α-pinene, β-pinene, camphene, d-limonene, p-cymene and α-terpinene. The highest total concentration of terpene compounds was observed in the coniferous forest. For the summer season, the total concentration of terpene compounds was highest in coniferous and mixed forests, and that was also highest in broad-leaved forest for the autumn.

The present study was designed to evaluate primary production organic matter in basin of lake around by execution of total maximum daily loading. BOD influent loading of Uiam lake was 2,819 kg/day, which was less then 28.3 percent, total effuluent loading as 3,619 kg/day, in comparision with BOD, total nitrogen influent loading was 4,681 kg/day, which was less then 10.0 percent, total effuluent loading as 5,150 kg/day. But in case of total phosphors influent loading was 73.3 kg/day, which was more then 34.2 percent, total run off loading as 48.3 kg/day. The result of survey reduction plan of primary production organic matter in basin of lake around which objectives of abstract is as follows. First plan was reduction of primary production organic matter by moving the outlet of municipal wastewater treatment center from present place to lake downstream. Secondary plan was improvement by diffusion type of outlet municipal wastewater treatment center. The third plan was reduction of environmental impact by passing and storing of municipal wastewater. Finally plan was decline water surface level which was present hydrouric retention time was reduction from 7.6 day to 6.0 day per meter.
