Freeze-thaw (FT) cycles occur annually in soils of mesic and frigid temperature regimes. FT has profound impacts on soil aggregates yet is often difficult to document in field settings. As a result, laboratory-based FT experiments are widely used, albeit with their own limitations. Both laboratory and field-based research indicates that aggregate properties vary with rates of freezing and thawing...
Agriculture has the dual attributes of being a carbon source and a carbon sink. The agricultural carbon compensation mechanism is important for increasing agricultural carbon sink and reducing agricultural carbon emissions. However, there is no specific entry threshold for the implementation of agricultural carbon compensation in China. Taking the two indicators of agricultural carbon sink level and...
Biochar’s production and application in soils has been suggested as a means of abating climate change by sequestering carbon while simultaneously providing energy and increasing crop yields. However, little is known about biochar’s effect on nitrification in alkaline soil. This study focused on the effect of wheat straw-derived biochar (0%, 2%, 5%, and 10%, w/w) on nitrification in a calcareous clay...
With the development of the economy and industrial construction, air quality deteriorates dramatically in China and seriously threatens people’s health. To investigate which factors most affect air quality and provide a useful tool to assist the prediction and early warning of air pollution in urban areas, we applied a sensor that observed air quality big data, information theory-based predictor significance...
The Hun River Basin is one of the most important heavy industrial and agricultural production bases of China. Its pollution level has exerted negative effects on human health. In order to investigate pollution levels and estimate the cancer risk of water in the river, water samples were collected in both the flood and dry periods. Pollution indicators were detected in terms of heavy metals, polycyclic...
The aims of current study are to asses the levels of heavy metals (Cr, Cu, Ni, Fe, Zn, Co, Pb, and Cd) in sediments of lakes in Yangtze wetland and discuss the relationships between the sources and human activities. A total of 54 samples covering seven lakes along the Yangtze route in Anqing were selected. The concentrations of metals in lake sediments were (mg-kg⁻¹): Cr, 4.08~12.58; Cu, 22.40~74...
