As an important source of methane emissions, rice fields account for 20% of global methane emissions and have a serious impact on global climate change. Paddy soils are rich in iron (Fe), and their redox processes are critical to the biogeochemical cycling of rice-field systems. However, it is not clear how iron oxides regulate the methanogenic capacity of different carbon sources. LUO dan and Prof. YAO huaiying from the institute of urban environment investigated the methanogenesis ...

Plastics are widely used because of their low cost, excellent performance and portability. It is predicted that by 2050, approximately 12,000 million tons of plastic waste will accumulate in the environment. Plastic fragments in the environment can decompose into microplastics (MPs) with diameters < 5 mm. Once MPs enter the soil, they usually require hundreds or even thousands of years to degrade and affect soil physicochemical properties and microorganisms in the long term. Biological v...
