Generation, sink, and emission of greenhouse gases by urban soils of reclaimed filtration fields

摘要

Intensive urbanization leads to the use of ecologically unfavorable areas for construction. Expensive remediation may not produce the desired results. Risks of boundary ecosystems include pollution, reducing biodiversity, and human health deterioration remains. This applies to the reclaimed sewage filtration fields. The main factor of their environmental hazard before remediation is the sludge rich in organic matter whose decomposition under reducing conditions leads to methane and carbon dioxide accumulation in soils and emission to the atmosphere.
