Summary: In this study, a spatial classification model was established for DEHP pollution levels using a Bi-LSTM neural network, considering the gradual reduction of sampling information with increasing distance between sampling and prediction points. A method was proposed for predicting the spatial distribution of soil pollution categories based on sparse samples, along with a model for the spatial distribution of organic pollution categories. The results show that the proposed method effectively predicts DEHP concentrations at different locations and categorizes the contamination levels, aligning well with the actual situation and verifying the validity of the method for rapid assessment of soil contamination levels based on sparse sampling.

Summary: The study aimed to evaluate the removal of PAEs in municipal wastewater treatment plants supported by constructed wetlands, with three new plant species being presented for the first time. Experimental data confirmed that Euonymus europaeus was the most effective plant species for the uptake of these compounds, making it optimal for supporting conventional MWWTPs.

Summary: This study investigated the occurrence, spatial distribution, and ecological risks of 16 PAEs in Taihu Lake during different seasons. Results showed that aside from the priority PAEs, other congeners also posed significant contamination and risks. Seasonal variation influenced PAE concentrations, with higher levels in the wet season and significant positive correlations with rainfall, water reserves, and water levels.

Summary: This study investigated the urinary concentrations of nine phthalic acid ester (PAE) metabolites in pregnant women in China. The results showed cumulative exposure to PAEs among pregnant women, and residential characteristics were found to be associated with urinary PAE metabolite concentrations. Living in buildings and using coal/kerosene/wood/wheat straw as domestic fuel were associated with higher health risks.

Summary: As microplastics gain global attention, the hazards of plasticizers (PAEs) have attracted people's attention in the field of agricultural soil. This study reveals, for the first time, the influence of PAEs residues on soil metabolic functions using high-throughput sequencing and metabolomics platforms. It is found that DBP treatment significantly changes the soil metabolite profile.

Summary: This study investigates the spatiotemporal distributions of six phthalic acid esters (PAEs) in the surface sediments of the Songhua River. The results show that the concentration of PAEs is higher in the spring compared to summer and autumn, and the upper reaches of the river have higher PAEs concentrations than the middle and lower reaches. Dibutyl phthalate (DBP) and di(2-ethylhexyl) phthalate (DEHP) are the most abundant PAEs. Ecological risk assessment reveals that DBP and DEHP pose moderate or high risks to aquatic organisms. Agricultural sources are identified as the primary contributor to the PAEs pollution.

Summary: This article reports a new biocatalytic strategy for the complete hydrolysis of phthalic acid esters (PAEs) using a bienzymatic degradation system. The researchers optimized the reaction conditions and investigated the substrate scope, finding that PAEs with relatively small alcohols were degraded to over 90%. This study provides a potential doable approach for the efficient degradation of PAEs.

Summary: This study investigated the impact of plant- and animal-derived biochar on the competitive sorption-desorption of potentially toxic elements (PTEs) and phthalic acid esters (PAEs) in soils with different organic carbon content. The sorption behavior was influenced by biochar type, application dose, and soil organic carbon content. Additionally, the reciprocal effect between DEP and Cd2+ was found to be a crucial factor affecting their sorption/desorption behavior by biochar, with pig carcass biochar showing greater efficacy in metal/DEP immobilization.

Summary: Agricultural films are widely used in high-intensity agriculture, but the low recovery rate leads to an accumulation of plastic mulch in agricultural soils. This study focuses on the exposure impact of BBP, a chemical introduced into soil ecosystems through the accumulation of plastic mulch, on earthworms. The study explores the effects of BBP on the digestive system, oxidative stress, and neurotoxicity in earthworms, providing insights into the molecular mechanisms underlying these effects.

Summary: Lake Bangong Co in western Tibet is a unique lake with spatial differences in water chemistry characteristics. Most water quality parameters meet standards, but Cl- and SO42- concentrations in the western part exceed limits. PAHs and PAEs mainly come from biomass combustion and domestic waste, while metals originate from natural and anthropogenic sources.

Summary: In this study, the distribution characteristics of ten typical phthalic acid esters (PAEs) were investigated in air samples collected from urban areas in Hanoi, Vietnam from May to August 2022. The total concentrations of PAEs in indoor and ambient air samples ranged from 320-4770 ng/m(3) and 35.9-133 ng/m(3), respectively. Among the PAEs studied, di-(2-ethyl)hexyl phthalate (DEHP) was found to have the highest levels in all air samples. The exposure levels of PAEs through inhalation were below the reference doses proposed by the US EPA for selected compounds.

Summary: We investigated the toxicological effects of single and combined exposure of the plasticizer di-(2-ethylhexyl) phthalate (DEHP) and the fluoroquinolone antibiotic enrofloxacin (ENR) on earthworms (Eisenia fetida) by analyzing oxidative stress, DNA damage, and changes in digestibility. Both DEHP and combined pollution treatments resulted in increased reactive oxygen species content in earthworms, while ENR alone had little effect. Malonaldehyde (MDA) was mainly cleared by glutathione sulfur transferase (GST), and DEHP caused more DNA damage than combined pollution. Both single and combined pollution reduced digestive enzyme activity, with combined pollution having a stronger effect. Cellulase, MDA, and GST were the most sensitive indicators. The toxicity ranking based on the Integrated Biological Response (IBR) index was ENR + DEHP > DEHP > ENR, showing a synergistic effect of combined toxicity. These findings highlight the significant ecological risk of phthalate esters and antibiotics in the environment.
