Inoculum selection and hydraulic retention time impacts in a microbial fuel cell treating saline wastewater.
Appl Microbiol Biotechnol
January 2025
Environmental Microbiology Group, Institute of Water Research, University of Granada, 18003, Granada, Spain.
Microbial fuel cell (MFC) technology has received increased interest as a suitable approach for treating wastewater while producing electricity. However, there remains a lack of studies investigating the impact of inoculum type and hydraulic retention time (HRT) on the efficiency of MFCs in treating industrial saline wastewater. The effect of three different inocula (activated sludge from a fish-canning industry and two domestic wastewater treatment plants, WWTPs) on electrochemical and physicochemical parameters and the anodic microbiome of a two-chambered continuous-flow MFC was studied.

This study provides comprehensive overview of the current level, sources and human exposure risk to hazardous polycyclic aromatic hydrocarbons (PAHs), polybrominated diphenyl ethers (PBDEs), and polychlorinated biphenyls (PCBs) in South American outdoor air. Research documents were obtainable for only 6 countries within the target period (2014 - 2024). For all contaminants, urban concentrations exceeded that of rural/remote locations.

Aquat Toxicol
January 2025
Basic Science Department, Preparatory Year, University of Ha'il, Ha'il City, 1560, Saudi Arabia.
This review article provides a thorough examination of an interaction between linear alkylbenzenes (LABs) and ecosystems. The review covers various aspects of LABs' impact on ecosystems, focusing on detection and treatment strategies to mitigate ecological consequences. It delves into LABs' role as molecular markers for sewage pollution, their physicochemical properties contributing to persistence, and their effects on aquatic and terrestrial organisms, including disruptions to endocrine systems.

Based on Marx's theory of international value, this paper analyzes the carrier of unequal exchange and the path of international transfer of surplus value, constructs an international division of labour status index by comprehensively observing the organic composition of capital in the export and import sectors, and tries to accurately grasp the characteristics of the current international division of labour pattern coexisting between horizontal products and vertical products. At the same time, based on the data of all available HS92 six-digit code categories in various countries in the world from 1993 to 2016, the level of international division of labour in China is empirically analysed. The results show that: (1) there is no breakthrough in the situation of China's low status of international division of labour; (2) the high capital-organic composition of the import sector is the main reason for the low status of international division of labour; (3) the continuous decline in the absolute value of captured surplus is a global phenomenon; (4) WTO accession has not significantly improved the status of international division of labour.

Greywater, originating from kitchen sinks and toilets, constitutes 75-80 % of the domestic wastewater produced in homes and can be reclaimed for non-potable uses. This study synthesized novel sludge-derived aluminosilicates and alginate-polyethyleneimine (PEI) biochar composites. The aluminosilicates offer a sustainable approach to sludge management, while alginate-polyethyleneimine presents a green biochar modification approach.
