As population growth and climate change add to the problem of water scarcity in many regions, the argument for using treated wastewater for irrigation is becoming increasingly compelling, which makes understanding the risks associated with the uptake of harmful chemicals by crops crucial. In this study, the uptake of 14 chemicals of emerging concern (CECs) and 27 potentially toxic elements (PTEs) was studied in tomatoes grown in soil-less (hydroponically) and soil (lysimeters) media irrigated with potable and treated wastewater using LC-MS/MS and ICP-MS. Bisphenol S, 2,4 bisphenol F, and naproxen were detected in fruits irrigated with spiked potable water and wastewater under both conditions, with BPS having the highest concentration (0.034-0.134 µg kg f. w.). The levels of all three compounds were statistically more significant in tomatoes grown hydroponically (

Surface Hydrophilic Modification of Polypropylene by Nanosecond Pulsed Ar/O Dielectric Barrier Discharge.

Materials (Basel)

December 2024

College of Electrical Engineering and Control Science, Nanjing Tech University, Nanjing 211816, China.

Polypropylene (PP) membranes have found diverse applications, such as in wastewater treatment, lithium-ion batteries, and pharmaceuticals, due to their low cost, excellent mechanical properties, thermal stability, and chemical resistance. However, the intrinsic hydrophobicity of PP materials leads to membrane fouling and filtration flux reduction, which greatly hinders the applications of PP membranes. Dielectric barrier discharge (DBD) is an effective technique for surface modification of materials because it generates a large area of low-temperature plasma at atmospheric pressure.

Article Synopsis
  • Coal-based humic acid residue (HAS) has potential as a nutrient-rich material for adsorbing harmful substances like mercury (Hg), and a modified version (N-HAS) was created to enhance its adsorption properties.
  • N-HAS demonstrated a strong capacity for Hg removal, with a maximum adsorption of 124.20 mg/g and stable performance over multiple cycles, effectively lowering Hg levels in both maize and contaminated soil.
  • The study highlighted that using N-HAS led to significant reductions in Hg content in maize kernels (up to 72.09%) and soil (up to 82.80%), with optimal results observed at an application rate of 0.4 kg/m.

Mitigating the release of extracellular antimicrobial resistance genes (exARGs) from wastewater treatment plants (WWTPs) is crucial for preventing the spread of antimicrobial resistance from human domains into the environment. This study aimed to evaluate the applicability of intI1 as a performance indicator for securing the removal of exARGs at WWTPs. We investigated the reduction of exARGs and intI1 in a full-scale WWTP, where identical wastewater was treated using conventional activated sludge (CAS) and membrane bioreactor (MBR) systems.

This review explores biochar's potential as a sustainable and cost-effective solution for remediating organic pollutants, particularly polycyclic aromatic hydrocarbons (PAHs) and pesticides, in water. Biochar, a carbon-rich material produced from biomass pyrolysis, has demonstrated adsorption efficiencies exceeding 90% under optimal conditions, depending on the feedstock type, pyrolysis temperature, and functionalization. High surface area (up to 1500 m/g), porosity, and modifiable surface functional groups make biochar effective in adsorbing a wide range of contaminants, including toxic metals, organic pollutants, and nutrients.

Valorization of mixed blackwater/agricultural wastes for bioelectricity and biohydrogen production: A microbial treatment pathway.

The management of wastewater and agricultural wastes has been limited by the separate treatment processes, which exacerbate pollution and contribute to climate change through greenhouse gas emissions. Given the energy demands and financial burdens of traditional treatment facilities, there is a pressing need for technologies that can concurrently treat solid waste and generate energy. This study aimed to evaluate the feasibility of producing bioelectricity and biohydrogen through the microbial treatment of blackwater and agricultural waste using a dual-chamber Microbial Fuel Cell (MFC).
