堆肥可以是N2 O和CH 4产生的来源。在这项调查中，不同的堆肥堆的有机生活垃圾进行了监测，重点是潜在的形成CH 4和N2 O的堆和排放这些气体的堆。所研究的堆肥堆具有不同的堆肥年龄，翻堆间隔和堆肥大小。分析的堆肥气体含有1-3421 μ L的N2 O-N L-1和0-470 mL的CH 4 L-1。堆肥的N_2O和CH_4排放速率分别为1- 1464mgN_2O·m ~（-2）·d ~（-1）和0 ~ 119000mgCH_4·m ~（-2）·d ~（-1）。堆肥气体组成和排放的这些非常大的差异表明堆肥管理的重要性。结果还提供了一个理解，在堆肥过程中的N2 O和CH 4的排放量增加可以发生。
Composting can be a source of N2O and CH4 production. In this investigation, different compost heaps of organic household waste were monitored with the focus on potential formation of CH4 and N2O in the heaps and emission of these gases from the heaps. The studied compost heaps had different compost ages, turning intervals and compost sizes. The analysed compost gases contained between 1-3421 mu L of N2O-N L-1 and 0-470 mL of CH4 L-1. The emission rates of N2O and CH4 from the compost heaps were between 1-1464 mg N2O m(-2) day(-1) and 0-119 000 mg CH4 m(-)2 day(-1). These very large differences in compost gas composition and emission indicate the importance of compost management. The results also give an understanding of where in the composting process an increasing emission of N2O and CH4 can occur.
