Abstract

Many greenhouse gases occur naturally, such as water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Others such as hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride ($SF_6$) result exclusively from human industrial processes. Current global warming has been linked to anthropogenic greenhouse gas concentration increases. Methods to quantify greenhouse gas emissions during animal agriculture and the possibility to apply those to circumstance in the world were studied. Various chamber methods with trace gas analyzer (TGA) were used to quantify greenhouse gas emissions from stored manure. Methane fluxes from pails storing liquid swine manure were measured. Methane emissions increased a little with time and mean was 393.2 ${\mu}g\;m^{-2}\;s{-1}$ (standard error : 4 ${\mu}g\;m^{-2}\;s{-1}$).

본 시험은 혐기조건하에서 돈슬러리로부터 발생하는 온실가스 연속측정 기술을 습득하고, 이를 이용해 온실가스의 일종인 메탄 발생량 및 시간대별 배출량 변화를 알아보기 위한 목적으로 수행하였으며, 그 결과는 다음과 같다. 1. TGA의 16 site에서 측정한 값들의 평균값은 2.437 ppm이었으며 표준편차는 0.024 ppm이었다. 각 site에서 평균값과 비교한 표준편차는 10% 이내였다. 따라서 각 site에서 측정된 값은 일정한 농도를 보인다고 할 수 있다. 2. 돈분뇨 액비에서 배출되는 $CH_4$을 측정하기 위해 돈분뇨 액비 저장조에서 액비를 샘플링하여 그것을 들통에 보관하였고, 들통에서 배출되는 $CH_4$ 배출량을 측정하였다. 들통 1, 2, 3의 $CH_4$ 배출량은 각각 413.9, 373.8, 그리고 391.9 ${\mu}g\;m^{-2}\;s{-1}$였고 세 들통의 평균값은 393.2 ${\mu}g\;m^{-2}\;s{-1}$이었다.
