Article Abstract
The presence of methoxychlor (MXC) in soil and wastewater is considered a nonnegligible environmental threat. Herein, FeO@Fe(0) was obtained by NaBH reduction of FeO nanoparticles and served as a carrier for laccase to construct catalyst. The catalyst was evaluated for the degradation of MXC in treated wastewater and soil with 2, 2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) being used as cocatalyst. The removal rate of MXC in wastewater and soil was found to be 89% and 88% in optimum conditions, and the influences of initial MXC concentration, pH, and temperature on the degradation rate were evaluated. The metabolites including 2-methylpentane, 3-methylpentane, and n-pentane of MXC were identified, and possible degradation mechanisms were proposed. Overall, this work successfully demonstrates not only the ability to degrade MXC in different circumstances but also provides a new idea for environmental remediation in the future.

Per- and polyfluoroalkyl substances (PFAS) are persistent organic pollutants with increasing prevalence in agricultural soils, primarily introduced through biosolid application, wastewater irrigation, and atmospheric deposition. This review provides a meta-analysis of terminologies across 145 peer-reviewed studies, identifying inconsistency in the classification of PFAS subgroups-such as "long-chain vs. short-chain," "precursors," and "emerging PFAS"-which hinders regulatory harmonization and model calibration.

The aim of the study was to evaluate the toxic metals (TMs) pollution, bioaccumulation and its potential health risk via consumption of different vegetables irrigated by different water sources released from industrial estates of Khyber Pakhtunkhwa. Water (fresh and waste), soil and vegetables samples were collected in triplicates and acid digested. Digestion of samples were followed by evaporation and filtration and then assessed for TMs via atomic absorption spectrophotometer.

Megadiverse countries, which collectively harbor over 70% of the planet's terrestrial biodiversity, play a crucial role in global conservation efforts. However, many of these nations, primarily in the developing world, face significant environmental challenges that threaten biodiversity, including pollution, habitat loss, and climate change. Among these issues, pollution-driven by industrialization, agriculture, and improper waste disposal-has emerged as a critical concern, particularly for water and soil ecosystems.

This work aims to investigate the occurrence of 31 antibiotics (ABs), 2 bacteria ( and spp.) and their counterpart antibiotic-resistant bacteria (carbapenem and cephalosporin families), and several antibiotic-resistant genes (ARGs) throughout a full distribution system of reclaimed water (RW) in a real-scale scenario. The RW was analyzed (i) before and after the tertiary treatment (sand filtration and chlorination), (ii) during the storage period in secondary ponds before its use in irrigation, and (iii) directly in the droppers installed in four plastic-based greenhouses over 9 months.

The effect of mixed potable and wastewater (WW) irrigation on leafy vegetables cultivated in southern Tehran, Iran, was investigated in 2022. Eight species-spinach (Spinacia oleracea), scallion (Allium fistulosum), radish (Raphanus sativus), cress (Lepidium sativum), basil (Ocimum basilicum), purslane (Portulaca oleracea), cilantro (Coriandrum sativum), and savory (Satureja hortensis)-were grown in calcareous loamy soil under greenhouse conditions using five irrigation regimes (0%, 25%, 50%, 75%, and 100% WW) applied every 2 days. Soil salinity, DTPA-extractable Co, Cu, Ni, and Zn, plant growth traits, and health risk indices-transfer factor (TF), bioaccumulation factor (BAF), average daily dietary intake (ADD), hazard quotient (HQ), and cancer risk (CR)-were determined for children and adults.
