산업폐기물 매립지의 표면에서 배출되는 메탄을 조사하였다. 여름철에는 45군데에서 24군데가 겨울철에는 42군데에서 20군데가 메탄의 흐름을 보이지 않았다. 메탄의 유입은 몇 군데에서 발견되었고, 여름에 흐름 비율은 -0.29~370ml/m<sup>2</sup>/min 이고, 겨울에는 -0.50~109ml/m<sup>2</sup>/min의 범위이다. 지상의 온도와 메탄 흐름은 확실한 상호관계를 보인다. 전체 메탄 배출은 지상온도관계와 지상 온도의 분포를 기초로 하여 평가한다. 전체 매립지로부터 배출되는 메탄은 여름철과 겨울철에 각각 0.57m<sup>3</sup>/hr과 0.039m<sup>3</sup>/hr였다. Investigation on the methane emission from the surface of waste landfill that contains industrial waste was executed. . Twenty-four out of 45 points in summer and 20 out of 42 points in winter showed no methane flux. Influx of methane was observed in a few points, and flux rate ranged from -0.29 to 370 ml/m<sup>2</sup>/min in summer and from -0.50 to 109 ml/m<sup>2</sup>/min in winter. Ground temperature and methane flux showed certain correlation. Whole methane emission was estimated based on the correlation with ground temperature and the distribution of ground temperature. Estimated methane emissions from the whole landfill estimated were 0.57 m<sup>3</sup>/hr and 0.039 m<sup>3</sup>/hr in summer and winter, respectively.
