Towards online surface water quality monitoring technology: A review
Environ Res. 2023 Sep 14:117147. doi: 10.1016/j.envres.2023.117147. Online ahead of print.ABSTRACTThe exponential growth of human population and anthropogenic activities have led to the increase of global surface water contamination especially in river, lakes and ocean. Safe and clean surface water sources are crucial to human health and well-being, aquatic ecosystem, environment and economy. Thus, water monitoring is a vital need to ensure minimal and controllable contamination in the water sources. The conventional surface water monitoring method involves collecting samples on site and then testing them in the laboratory...

How does climate policy uncertainty affect green technology innovation at the corporate level? New evidence from China
Environ Res. 2023 Aug 28:117003. doi: 10.1016/j.envres.2023.117003. Online ahead of print.ABSTRACTThe frequent occurrence of extreme weather reminds us to focus more attention on sustainable development. A panel of Chinese A-share listed companies is selected as a research sample to explore how climate policy uncertainty has an effect on companies' green technology innovation. According to the empirical findings, corporate green technology innovation is negatively related to the uncertainty of climate policy. By affecting their R&D investments and risk tolerance, corporations' ability to develop in green technologies h...

Sugarcane-bagasse-ash in enhanced mesophilic Co-digestion for biogas and nutrient recovery: A concept of developing rural circular bioeconomy
This study disclosed the a role of sugar cane bagasse ash (SCBA) in enhancing the bioenergy (biogas) yield and digestate fertility via anaerobic co-digestion (AcoD) of buffalo dung (BD) and vegetable residue (VR) under mesophilic conditions (37 ᴼC). Firstly, an optimal BD/VR ratio (1:3) was determined based on biogas yield by introducing five different BD/VR ratios (1:0, 3:1, 1:1, 1:3, and 0:1) into AcoD systems. Secondly, the biogas yield was increased further by adding SCBA at five different concentrations (0, 0.5, 1, 1.5, and 2 wt%). Experimental results disclosed that the 1.5 wt% of SCBA gave the highest cumulative b...

Preparation of dopamine-modified sea squirt cellulose hydrogel dust-fixing agent to prevent raising of dust
In this study, cellulose was extracted from sea squirts, and its hydrophilic properties were improved by substituting the hydrogen ions of the cellulose -OH with dopamine. The modified cellulose was used to prepare a hydrogel for use as a dust-fixing agent (CDP) to reduce air pollution caused by dust. After response surface method optimization, the proportions of binder, water-retaining agent, wetting agent, and antifreeze in CDP were 0.97, 1.44, 0.23, and 6.32%, respectively. This composition improved the wetting ability and permeability of CDP on particle surfaces. CDP exhibited good water retention at -11-50 °C. CDP re...

Synthesis & amp; fabrication of O-linked polymeric hybrids for recovery of textile dyes: Closed loop economy
Environ Res. 2023 Jul 30:116780. doi: 10.1016/j.envres.2023.116780. Online ahead of print.ABSTRACTDyes are an important resource employed for the production systems in textile, paper, paint and leather industry. An estimate of 200,000 tons of dyes are discharged as textile effluent each year worldwide. It becomes imperative to recover these dyes by treating the effluents using economically viable routes. The present research was undertaken with the objective to attain zero emission and zero waste through development of novel polymeric hybrids as adsorbents. For this purpose, metal moieties (Al3+, Si4+, Ti4+ and Zr4+) were ...

Life cycle assessment and circularity of polyethylene terephthalate bottles via closed and open loop recycling
Environ Res. 2023 Jul 28:116788. doi: 10.1016/j.envres.2023.116788. Online ahead of print.ABSTRACTPolyethylene terephthalate (PET) recycling is considered as one of the key approaches to achieving the circular economy (CE) of plastic waste. Bottle-to-Bottle and Bottle-to-Fiber recycling were assessed using Life Cycle Assessment (LCA) and Material Circularity Indicator (MCI). Three allocation methods (i.e., substitution, recycled content, and economic allocation) were used to deal with the recycling system. Producing bottle-grade PET resin and polyester fiber from PET bottle waste can reduce environmental impacts for most m...

Can urban land market reform mitigate industrial emissions? Environmental evidence from 257 prefecture-level cities in China
Environ Res. 2023 Jul 19:116707. doi: 10.1016/j.envres.2023.116707. Online ahead of print.ABSTRACTIn the period of planned economy, China used low-cost land investment to drive economic development for a long time, which brought problems such as low efficient use of natural resources and environmental pollution. Under the dual pressure of economic development and environmental protection, Chinese government has begun to implement the urban land market reform, hoping to gradually change the extensive economic development model with high input and low output through the market mechanism. In order to investigate whether the u...

Relationship among marine pollution, outdoor activities, and climate change: Fresh evidence from panel threshold regression analysis from coastal regions of China
Environ Res. 2023 Jul 15:116668. doi: 10.1016/j.envres.2023.116668. Online ahead of print.ABSTRACTThe mitigation of oceanic pollution is believed to be influenced by the expansion of marine economies and advancements in technology, as per existing research. Nevertheless, the current body of research on this topic is lacking in terms of exploring the potential nonlinearity of the relationship and fully understanding the extent to which the observed effects have been demonstrated. The present study endeavors to bridge the existing research void by investigating the coastal regions of China spanning the time from 2000 to 2020...
