Article
The environmental concerns caused by textile waste require technological development to support recycling and re-utilization. Incineration and landfill of textile waste are still widely used, and they lead to soil and water pollution as well as emissions of greenhouse gases. Recently, various research studies on textile waste treatment try to find...
Article
Liquid transportation biofuel production is a promising strategy to reduce greenhouse gas emissions. Hydrothermal gasification (HTG) has shown great potential as an effective method for valorizing wet biomass. The high-quality syngas produced using the HTG process can be chemically/biochemically converted to liquid biofuels. Therefore, this paper a...
Article
Mercury has become a ubiquitous hazardous element even ending up in pristine areas such as the Arctic, where it biomagnifies and leaves especially top predators vulnerable to potential health effects. Here we investigate total mercury (THg) concentrations and dietary proxies for trophic position and habitat foraging (δ¹⁵N and δ¹³C, respectively) in...

The chemical industry is the leading sector in the EU in terms of added value. However, contaminants pose a major threat and significant costs to the environment and human health. While EU legislation and international conventions aim to reduce this threat, regulators struggle to assess and manage chemical risks, given the vast number of substances...

Necropsy on an adult male pilot whale stranded in Denmark in an area with heavy boat traffic revealed internal lesions in the head and neck region, while the exterior did not show any visible lesions. We found multiple fractured bones, muscle trauma and extensive hemorrhage including a fractured occipital bone with several fragments and bone pieces...
Article
Eight to ten percent of total global greenhouse gas emissions are associated with food loss and waste. Tackling the challenges of food loss and sustainable food waste management is key to fulfilling the Paris Agreement. However, among the Nationally Determined Contributions to the Paris Agreement, very few countries make references to food loss and...
Article
The rapid development of textile industry and improvement of people's living standards have led to rapid production of cotton textile and simultaneously increase the production of textile wastes. Cotton is one of the most common textile materials, and the waste cotton accounts for 24 % of the total textile wastes. To effectively manage the wastes,...

Nanoplastics are emerging contaminants of concern for living organisms and ecosystems, yet nanoplastics are difficult to extract and analyse. Once released into the environment, the fate and behavior of nanoplastics are controlled by physical, chemical, and biological factors. Here, we review nanoplastics weathering, aggregation, biofouling, and bi...

The tremendous rise in the consumption of antimicrobial products had aroused global concerns, especially in the midst of pandemic COVID-19. Antimicrobial resistance has been accelerated by widespread usage of antimicrobial products in response to the COVID-19 pandemic. Furthermore, the widespread use of antimicrobial products releases biohazardous...
Article
Raw biochar with high pH possibly stimulated ammonia (NH3) volatilization in the agricultural soil. We hypothesized that the modified biochar (MBC) with low pH can synchronically decrease the NH3 and nitrous oxide (N2O) losses. We performed a two-year experiment to clarify how citric acid MBC influence the NH3 volatilization and N2O emission as wel...
Article
Worldwide regulatory agencies should (re)examine the consideration of: (i) sub-threshold responses, (ii) non-linear dose-response models able to detect sub-threshold responses of both a beneficial and detrimental nature, and (iii) abandoning the use of default dose-response models for their risk assessment. Mounting evidence for significant sub-thr...

Over the past decade, conductive metal–organic frameworks (CMOFs) have attracted great attention. Synthesis of CMOFs has been achieved through metal–ligand coordination, ligand-ligand stacking, redox activity and post-synthesis conductive strategies including post modification, doping and guest induced conduction. Herein, we review the recent devel...
Article
Increasing municipal solid waste (MSW) generation and environmental concerns have sparked global interest in waste valorization through various waste-to-energy (WtE) to generate renewable energy sources and reduce dependency on fossil-derived fuels and chemicals. These technologies are vital for implementing the envisioned global “bioeconomy” throu...

Among three energy products of oil, char, and gas from pyrolysis, char has the advantages of easy operation and low cost. It is expected that pyrolysis of waste materials using a desired heating source and optimal operation parameters can achieve max pyrolysis char yield with good higher heating value (HHV). Here we evaluate the effects of four hea...

Hunting with lead-based ammunition poses a significant health risk to humans, wildlife and ecosystems and is a One Health issue in the Arctic. Lead is highly toxic, and there is no safe level of exposure. In humans, even a moderate intake of meat from game harvested with lead-based ammunition may bring the blood lead level above thresholds for docu...
