Analysis of income inequality and environmental pollution in BRICS using fresh asymmetric approach.

Environ Sci Pollut Res Int 2021 May 12. Epub 2021 May 12.

Pakistan Institute of Development Economics (PIDE), Islamabad, Pakistan.

With rapid economic growth, BRICS is facing enormous burdens of carbon emission and severe issues of income inequality. However, behind this economic success, the BRICS economies also face few thoughtful challenges to improve environmental quality by catching up the sustainable development goals. Consequently, the existing empirical research is concerned with the dynamic links between income inequality and CO emissions by using the novel nonlinear ARDL approach, but small attention has been paid to the BRICS in literature.

Geochemical distribution and speciation of thallium in groundwater impacted by acid mine drainage (Southern China).

Chemosphere 2021 May 4;280:130743. Epub 2021 May 4.

School of Environmental Science and Engineering, Guangzhou University, Guangzhou, 510006, China.

Thallium (Tl) commonly occurs in shallow groundwater affected by acid mine drainage (AMD); however, our knowledge of the occurrence of Tl in shallow groundwater is limited. This study observes that the shallow groundwater in an AMD-impacted area in Southern China contains an elevated Tl concentration (22 μg/L) under the oxidizing conditions and a low Tl concentration (<1 μg/L) in the reducing environment. The groundwater Tl concentration is positively correlated with oxidation-reduction potential (Eh) and negatively correlated with Cl content. Read More

High-Efficiency and Sustainable Desalination Using Thermo-regenerable MOF-808-EDTA: Temperature-Regulated Proton Transfer.

ACS Appl Mater Interfaces 2021 May 11. Epub 2021 May 11.

State Key Laboratory of Pollution Control and Resource Reuse, School of the Environment, Nanjing University, Nanjing 210023, China.

Adsorption as a desalination approach has the advantages of energy efficiency, low cost, and operational convenience, but its practical application is limited by low desalination capacity, consumption/disposal of strong acids/bases as regeneration reagents, and poor reusability. Herein, we synthesized a thermo-regenerable salt absorbent by grafting ethylenediaminetetraacetic acid (EDTA) onto a metal-organic framework (MOF), MOF-808-EDTA, which could rapidly adsorb NaCl within 30 min from saline water at 25 °C with a desalination capacity as high as 9.4 mmol/g.

Elevated Atmospheric CO and Nitrogen Fertilization Affect the Abundance and Community Structure of Rice Root-Associated Nitrogen-Fixing Bacteria.

Front Microbiol 2021 21;12:628108. Epub 2021 Apr 21.

Ministry of Education Key Laboratory of Ecology and Resource Use of the Mongolian Plateau and Inner Mongolia Key Laboratory of Grassland Ecology, School of Ecology and Environment, Inner Mongolia University, Hohhot, China.

Elevated atmospheric CO (eCO) results in plant growth and N limitation, yet how root-associated nitrogen-fixing bacterial communities respond to increasing atmospheric CO and nitrogen fertilization (eN) during the growth stages of rice is unclear. Using the gene as a molecular marker, we studied the combined effect of eCO and eN on the diazotrophic community and abundance at two growth stages in rice (tillering, TI and heading, HI). Quantitative polymerase chain reaction (qPCR) showed that eN had no obvious effect on abundance in rice roots under either ambient CO (aCO) or eCO treatment at the TI stage; in contrast, at the HI, copy numbers were increased under eCO and decreased under aCO.

Technology and Concept of Wastewater Treatment: Differences Between the Rhine Basin and the Yangtze Basin.

Bull Environ Contam Toxicol 2021 May 8. Epub 2021 May 8.

State Key Laboratory of Pollution Control and Resource Reuse, School of the Environment, Nanjing University, 163 Xianlin Ave., Nanjing, 210023, China.

Based on field visits and literature research, the situations of several typical wastewater treatment plants (WWTPs) in the Rhine basin and the Yangtze basin were investigated, to compare the technology and concept of wastewater treatment in these two areas. Our results showed that WWTPs in the Rhine performed well in pollutant removal, and have shifted their focus to energy production and nutrient recovery; While in the Yangtze basin, most WWTPs still operate on the sole concept of pollution treatment. Though China's WWTPs attach importance to water reclamation, the related technologies are still under development. Read More

CoS nanoparticles-embedded porous carbon: A highly efficient sorbent for mercury capture from nonferrous smelting flue gas.

J Hazard Mater 2021 Jun 25;412:124970. Epub 2020 Dec 25.

School of Metallurgy and Environment, Central South University, Changsha 410083, China; Chinese National Engineering Research Center for Control & Treatment of Heavy Metal Pollution, Changsha 410083, China. Electronic address:

In this study, a novel CoS nanoparticles-embedded porous carbon (CoS-PC) was designed as an effective reusable sorbent for Hg capture from smelting flue gas. Some flue gas components can create more active sites on CoS-PC for Hg adsorption, but compete with Hg for the same sulfur sites over nano CoS/CoS (CoS) and CoS/CoS embedded porous carbon (CoS-PC), which can be ascribed to the difference in crystal structure between CoS and CoS/CoS. Therefore, CoS-PC shows much better Hg capture ability than CoS and CoS-PC under smelting flue gas. Read More
