Summary: The study investigated the effects of plastic pollution on the adsorption and degradation behaviors of pesticide residues in soil. The results showed that the presence of different types of microplastics can alter the adsorption and degradation rates of pesticides in soil. The different types of microplastics have varying effects on the degradation process of pesticides in soil.

Summary: Pesticides have been widely used in agriculture for pest control, with organophosphate pesticides being one of the most commonly used types. These pesticides cause irreversible inhibition of the AChE enzyme in living beings, leading to respiratory and neuromuscular impairments. The residues of organophosphate pesticides pose a threat to the environment and human health, with research focusing on the toxicological effects and methods of detection and degradation.

Summary: Risk estimation for pesticide analysis in homogeneous spice products like paprika was conducted using sampling and subsampling uncertainty. The minimum weight for subsampling, which minimizes overall uncertainty, was estimated based on subsampling results. The study found that subsampling has higher uncertainty compared to sampling due to high homogeneity in the manufacturer's batch. Additionally, Monte Carlo simulation showed that uncertainty is lower for subsample weights between 20 and 30 g but increases for sample sizes of 100 g. The simulated values from the MC method were confirmed for a saffron sample size of 30 g.

Summary: Two Capillary Electrophoresis methodologies were developed for the enantioseparation of prothioconazole and its metabolite prothioconazole-desthio. The methods showed good performance in analyzing commercial agrochemical formulations and conducting degradation studies in environmental matrices. The enantiomers of prothioconazole were separated within 4.5 minutes with a resolution of 2.8, while the simultaneous enantioseparation of prothioconazole and prothioconazole-desthio was achieved within 5.5 minutes with resolution values of 1.9 and 8.2, respectively.

Summary: This study investigated the composition and degradation pathways of pesticide-contaminated agricultural soils and natural soils using high-throughput sequencing. The results showed significant differences in bacterial communities, degradation genes, and metabolic pathways between the pesticide-contaminated soils and natural soils. These findings highlight the importance of using metagenomic methods to predict microbial-mediated degradation in contaminated environments.

Summary: Compound-specific isotope analysis (CSIA) is a powerful tool for evaluating the transformation of organic pollutants in the environment, but has limited application to micropollutants like pesticides due to lack of appropriate extraction methods. This study presents simple extraction methods for carbon and nitrogen CSIA for various environmental matrices and specific pesticides, with minimal impact on the stable isotope signatures of the pesticides.

Summary: Developing sensitive practical sensors for monitoring pesticide residues in edible foods and environmental samples is of vital importance for food safety and environmental protection. In this study, a target triggered porphyrin metal-organic framework (MOF)-based nanosystem was designed with the dual functionality of sensitive detection and controllable degradation of the triazophos pesticide. The intelligent multifunctional MOF system demonstrated the potential of programmable systems for jointly controllable tracking and elimination of pesticide residues in the environment, providing a new pathway for designing a precise mechanism for stimulus-triggered degradation of pesticide residues accompanied by sensitive detection for environmental friendliness and food safety.

Summary: Pesticides are chemicals used in agriculture to regulate plant growth and control pests, but their extensive use has led to serious pollution that threatens the environment and human health. Photocatalytic degradation of pesticides using semiconductor-based photocatalysts has become a promising method to address this issue. This review classifies pesticides based on their targets and chemical structures, and examines recent developments in semiconductor-based photocatalysts for pesticide degradation. The review also discusses various modification strategies to enhance the photocatalytic performance, such as doping, heterojunction construction, defect engineering, and anchoring single atom catalyst. Furthermore, the review emphasizes the need for a deeper understanding of the photodegradation mechanism through monitoring key intermediates, and provides perspectives on the challenges and future directions in developing high-performance semiconductor-based photocatalysts for pesticide degradation.

Summary: Pesticides are chemicals used in agriculture to regulate plant growth and control pests, but their extensive use leads to serious pollution that endangers the ecological environment and human health. Photocatalytic degradation of pesticides using semiconductor-based photocatalysts is a promising method to tackle pesticide pollution. This review classifies pesticides based on their targets and chemical structures, and discusses the recent developments in semiconductor-based photocatalysts, including metal oxides, metal oxyhalides, carbon nitrides, and metal sulfides, for pesticide degradation. Modifications strategies such as doping, heterojunction construction, defect engineering, and anchoring single atom catalysts to enhance the photocatalytic performance are described. In addition, understanding the photodegradation mechanism by monitoring key intermediates is important. The review also elaborates on the key challenges and future directions in developing high-performance semiconductor-based photocatalysts for pesticide degradation.

Summary: Excessive and irrational pesticide use has led to damage to the environment and human health. Nanoparticle-based sensors offer low detection limits, high sensitivity, and ease of use as compared to conventional spectrophotometry methods. A paper-based sensing device that utilizes luminescent silica quantum dots immobilized into a cellulose matrix has been developed for fast screening and readout from a smartphone. This device shows the potential for on-site detection of pesticides in biological and environmental samples.

Summary: In this study, purpald functionalized silver nanoparticles (P-AgNPs) were used as a colorimetric probe for the detection of acetamiprid pesticide in food and environmental samples. The P-AgNPs were characterized using various spectroscopic and microscopic techniques. The SPR band of P-AgNPs showed a decreasing absorbance with increasing acetamiprid pesticide concentration due to P-AgNPs aggregation. The method demonstrated excellent linearity and low detection limit for acetamiprid pesticide analysis in various samples.
