Summary: Pesticides, synthetic substances widely used in agriculture-based food production, are monitored using mid-infrared spectroscopy and chemometric methods to evaluate their impact on the environment and ensure food quality. In this study, the use of MID-IR spectroscopy by attenuated total reflectance (ATR) and functionally-enhanced derivative spectroscopy (FEDS) is proposed for non-destructive and simple monitoring of pesticides. The methodology is successfully applied to detect Chlorpyrifos residues in banana peel.

Summary: This research presents the microwave-assisted synthesis of CdS/carbon/MoSx hybrids used as photocatalysts for degrading 4-nitrophenol. The hybrids showed variable photocatalytic activity, with the ternary composite using ascorbic acid as a precursor exhibiting excellent performance in degrading 4-nitrophenol within 45 minutes of irradiation. This suggests potential applications of such ternary hybrids in removing toxic water-soluble substances.

Summary: In this study, polyindole/tungsten trioxide (PIn/WO3) nanocomposites were prepared and characterized for the first time, with investigations into their structural properties and frequency-dependent electrical features. The average particle size of WO3 was found to be between 15.36 and 44.71 nm, and dielectric analysis showed a decrease in ε' values with increasing WO3 content in the PIn matrix at low frequencies. Electric modulus analysis indicated an increase in M' value with frequency, suggesting the presence of short-range mobile charge carriers contributing to electrical conductivity.

Summary: The co-contamination of antibiotic norfloxacin significantly influences the dissipation and distribution of herbicides in water-sediment environment, especially prolonging the residues of herbicides in sediment. However, only the degradation of acetochlor is notably inhibited by norfloxacin, while enantioselective degradation shows minimal impact in the presence of norfloxacin.

Summary: This study investigated the impact of oxytetracycline on the environmental fate and metabolic profile of atrazine, revealing that oxytetracycline significantly inhibited the degradation of atrazine and altered the composition of its metabolites. Oxytetracycline also decreased the detoxification of atrazine and increased the percentage of toxic metabolites in soil. This could lead to increased environmental problems.

Summary: After application, pesticides remaining in fields have the potential to contaminate water resources and pose a threat to aquatic ecosystems. This study demonstrated that the free floating aquatic plant Eichhornia crassipes can effectively accumulate and remove triazine pesticides from water-sediment microcosms, with root accumulation and translocation depending on the hydrophobicity of the pesticides. Microbial degradation in sediment was found to be the main pathway for removing terbuthylazine in the microcosm.
