This work evaluated the removal efficiency of 13 wastewater-borne pharmaceuticals in a pilot constructed wetland (CW) operated under different aeration strategies (no aeration, intermittent and continuous). Aeration improved conventional wastewater parameters targeted micropollutants, compared to non-aerated treatment. Reduction chemical oxygen demand (COD) total nitrogen (TN) was slightly high...

Modern urbanized societies are facing serious challenges in the maintenance of their water resources [...]

Abstract The development of societies and the increasing growth recent constructions, especially in cities, have caused environmental issues, destruction, reduction natural resources environment, green green-blue spaces. According to studies, past years, many parts even pristine surfaces spaces big cities been turned into artificial, impermeable spaces, which has aggravated ecological problems ...

The aim of this study was to analyze the occurrence of sulfonamide resistance genes (sul1-3) and other genetic elements as antiseptic resistance gene (qacEΔ1) and class 1 and class 2 integrons (int1-2) in the upper layer of substrate and in the effluent of microcosm constructed wetlands (CWs) treating artificial wastewater containing diclofenac and sulfamethoxazole (SMX), which is a sulfonamide...

Understanding wetland changes under urbanization is important for wetland management. In this study, net transition intensity (NTI) and total transition intensity (TTI) are presented to characterize wetland transitions based on spatial data obtained from Landsat satellite images of Pearl River estuary in South China. NTI is commonly used to represent changes in absolute amounts for each class o...
