link1:https://doi.org/10.1002/lno.12179Throughout the history, humans have sprung up disproportionately along rivers and have extensively modified riparian zones. Today, many rivers have a long history of human alteration through urbanization. Urbanization has multiple effects on riverine biota among which the plankton that form the base of aquatic food webs.China’s economic reform and opening up policy has brou...

link2:https://doi.org/10.1016/j.memsci.2022.120767High salinity wastewater is with a salinity at least of 3.5wt%. Its compositions are mainly soluble ions, such as Cl-、SO2-、Na+、Ca2+ and Mg2+, as well as heavy metal ions with varying concentrations. And desulfurization wastewater from power plants is a typical high salinity wastewater. Treatment processes of high salinity wastewater normally acquire high enerhy consumptio...

Institute of Urban Environment Achieved New Progress in Biogeographical Patterns of Bacterial Communities and Their Antibiotic Resistomes in the Inland Waters of Southeast China
Antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) are ancient and common in the environment. However, human activities have accelerated their evolution, proliferation and dissemination in and across different ecosystems. ARGs can be transferred between environmental bacteria and human pathogens by horizontal gene transfer (HGT) through mobile genetic...Antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) are ancient and common in the environment.

Researchers reviews recent development for mitigation N2O emissions in agricultural soils
Nitrous oxide (N2O) is also an ozone-depleting substance. Farming activities account for nearly 60% of total anthropogenic N2O emissions. The manufactured nitrogen (N) fertilizers applied to soils are major sources of N2O emissions from agricultural systems. Among the synthetic N fertilizers, urea has the highest nitrogen content of all solid nitrogenous fertilizers and acco...

Researchers Propose a Novel Method for Nondestructive Silicon Wafer Recovery from End-of-Life PV Module
The fast-growing development of environmentally friendly energy generation methods have brought about the explosion of photovoltaic (PV) modules in recent decades. To date, the estimated cumulative installed capacity of PV modules has dramatically increased to 715 GW globally and 259 GW in China. In this regard, the limited lifetime (~25 years) of PV modules will lead to a s...
