Decoupling water use from economic development is a fundamental strategy to improve environmental quality from the source. It can promote economic growth while reducing water use and water pollution. This article uses water footprint theory to calculate the relevant indicators of the water quantity footprint and water quality footprint of the Northwest arid region between 1997 and 2017. This paper not only comprehensively consider the impact rate of economic development on water resource consumption and water pollution, but also analyzes the coordination of water resource utilization efficiency and economic development from the perspective of water resource flow, and make up for the deficiencies of pure consideration of water resource consumption. The results of the study show that in the past 20 years, the water resources utilization and economic development in Northwest arid region of China has shown relatively decoupling and weak negative decoupling, and the decoupling index of water quantity and water quality with economic development are 0.3377 and 0.3156, respectively. It shows that the dependence of economic development on water resources is gradually decreasing. However, the water shortage remains serious, this also shows that the efficiency of water use has not improved. selleck products Only if economic development is decoupled from water quantity and water quality at the same time, we can achieve sustainable development of water use and economy. We also found that the proportion of agricultural production water is too large, industrial water consumption is declining, and the proportion of domestic water consumption is increasing. There is a problem of unreasonable utilization structure and it can be seen from the wastewater discharge data that the discharge of industrial wastewater is declining. The government needs to focus on the wastewater treatment, strengthen the awareness regarding of water conservation at same time, and use stepped pricing standards to reasonably control water use.During the COVID-19 pandemic lockdown, emissions of primary criteria pollutants in the Mexico City Metropolitan Area (MCMA) were substantially reduced, as in many other cities in the world. Unexpectedly, the daily average ozone concentration profile was practically indistinguishable from that of the past two years for the same time span in the calendar. So, we compared surface meteorology data, CO, NOx and O3 hourly concentrations in the MCMA from the ozone season (from March 1 to May 31) for the years 2018, 2019, and 2020. Also, TROPOMI satellite data on column count of CO, NO2 and HCHO, above a sparse grid of surface points in the MCMA, were also compared for March, April, and May 2020 with those from 2019. Population density used as a background variable to increase understanding of the observed differences allowed us to propose that reductions in NOx were so drastic that ozone formation moved rapidly from a VOC sensitive region towards a NOx sensitive region. The relevance of that unplanned policy provides impacts of contingent short-term emissions control actions during very high pollution episodes. Further analysis of these and other related data concerning VOC speciation and emissions patterns during the coronavirus lockdown may provide guidelines to enhance emission control policies in the post-COVID-19 times to come.Saltwater intrusion has greatly impacted the functions of coastal wetland soils worldwide by increasing the salt stress; desalinization via freshwater restoration has been suggested to recover saline wetland soils and biodiversity, but its effectiveness is debated. To evaluate the desalinization effectiveness, we characterized the microbial communities and activities using high throughput 16S rRNA gene sequencing and 15N isotopic techniques in freshwater restored (≥10 years) and unrestored wetlands, and then compared the data with reported values of original freshwater wetlands in one of the most dynamic coastal areas, Yellow river estuary (YRE). Our data revealed that freshwater input significantly increased the soil organic carbon (SOC; P less then 0.05) after 10 years of restoration, yet it was still 10 times lower than the reported values of original freshwater wetlands. In general, microbial community showed higher diversities and more co-occurrence interactions in the restored than unrestored wetlandsoil microbial communities and their activities have been frequently reported in previous studies all around the world; however, it remains largely unknown about whether the microbial communities and their activities can be recovered or not in soil suffered salinization. Desalinization via freshwater restoration is supposed to offer a good solution to soil salinization in coastal area, but the effectiveness is debated. Here, we are presenting the long-term of field study related to the desalinization effects on microbial diversity, co-occurrence and functions, and find desalinization via freshwater restoration can recover most of microbial communities up to the similar levels of that in original freshwater wetlands, and highly improved microbial diversity and their functions, which sheds a positive light on soil desalinization via freshwater restoration at microenvironments.Tungstophosphoric acid (TPA) encapsulated dendritic fibrous silica KCC-1 was prepared via a microemulsion system with the simple reflux method using cetyltrimethylammonium bromide as a structure-directing agent. The TPA impregnated on KCC-1 (ITPA-KCC-1) was also prepared for comparative. Various physicochemical techniques were used to characterize the synthesized materials and their activity evaluated in the 5-hydroxymethylfurfural (HMF) formation from carbohydrates derivatives of fructose, glucose and cellulose. The effect of various factors such as catalyst to substrate ratio, different solvents and temperature were investigated on the formation of HMF. The resultant encapsulated catalyst was very active in fructose dehydration with the yield of 92% HMF and full conversion of fructose at 120 °C for 30 min under the microwave heating condition without any salt additive in the THF solvent system as well as 95% in MIBK solvent. The HMF yield was achieved by 58% and 16.2% from glucose and cellulose in the DMSO solvent, respectively.
