Summary: Organic pesticides are significant sources of soil pollution in agricultural lands, and their accumulation in human bodies is concerning. In this study, the presence of 18 pesticides in natural soil samples from agricultural lands was investigated, revealing the effectiveness of photocatalytic degradation using TiO2 or ZnO photocatalysts under UV radiation. The results showed that the five most abundant pesticides could be completely degraded within 20-24 hours using these photocatalysts, with TiO2 demonstrating higher activity. Notably, the persistent and toxic organochlorine pesticide heptachlor was completely degraded within 30 hours for the first time in soil using TiO2 photocatalyst.

Summary: This study developed and validated a liquid chromatography-mass spectrometry (HPLC-MS/MS) method for detecting pharmaceutical and pesticide residues in mussels. The method successfully detected target analytes at different concentration levels with high accuracy and low relative standard deviation for both intra-day and inter-day analyses. The method was applied to mussel samples collected from a commercial farm near the Adriatic Sea, detecting various contaminants within a certain range. The study provides a valuable tool for investigating the potential threats posed by diverse contaminant classes with high annual tonnage.

Summary: This study investigated the influence of five surfactants on the sorption-desorption, degradation, and mobility of fungicides in soils. The results showed that HDTMA increased fungicide sorption, while SDS and TX-100 decreased sorption. SDS also promoted fungicide degradation, especially in non-volcanic soil, while TX-100 enhanced the degradation of OH-CTL in all soils.

Summary: Phosphate fertilization leads to uranium input in agricultural soils, with uranium expected to associate with colloids and be subject to erosion, accumulating in soils with fine structure. However, the study found that uranium concentrations were slightly higher in vineyard model soils in Rhineland-Palatinate, Germany, and were mainly correlated with carbonate content and soil texture.

Summary: A QuEChERS sample preparation method was developed for small wildlife animals' liver tissues to analyze pesticide and pollutant exposure, allowing for multiresidue analysis with gas chromatography coupled to tandem mass spectrometry. The methods were validated with representative analytes, showing satisfactory results in recovery, precision, and linear range. The new micro QuEChERS method requires minute amounts of biomaterial and is a sophisticated technique for determining exposure to different contaminants.

Summary: This study provides a new interpretation of pesticide soil standards by introducing average and ceiling legal limits, revealing their implications. It shows that most pesticides can be regulated by both average and ceiling limits. Additionally, a case study on chlorpyrifos soil standards demonstrates that they can protect population health contrary to previous findings.

Summary: This study in Tai Lake, East China, identified high concentrations of organophosphorus pesticides and their degradation products in surface water, with agricultural areas showing more contamination than residential and industrial regions. Compounds like parathion and fenthion posed high ecological risks. Degradation products were also found at non-trivial levels, highlighting the potential threat they pose to natural environments.

Summary: The search and identification of organic contaminants in agricultural watersheds is crucial for understanding watershed contamination by pesticides. Recent advances in analytical strategies, such as non-target and suspect screening analysis, have provided a more comprehensive view of watershed contamination. However, the lack of analytical standards and suspect databases for unknowns, such as pesticide transformation products, limits the scope of suspect screening analysis to known molecules.

Summary: This study used HPLC-HRMS and Compound Discoverer 3.3 to screen dimethachlon degradation products in soils. Four metabolites were confirmed, and a quantitative analysis method was developed. Dimethachlon degraded quickly with a half-life of less than 1 day in nonsterile soils, and the metabolite DCBAA had a greater impact on soil enzyme activity than the parent compound.

Summary: This study investigated the sorption, desorption, and mobility of microencapsulated chlorpyrifos (CPF-MC) in two typical soils. The results showed that the sorption isotherms of CPF-MC and emulsifiable concentrate of chlorpyrifos (CPF-EC) in silt loamy soil were similar, while there was a considerable difference in sandy soil. The desorption processes of CPF-EC were controlled by soil affinity to CPF, while CPF-MC desorption was affected by the release rate of CPF from capsules. In terms of mobility, CPF-EC was found to leach in silt loam soil, but CPF-MC was not vertically mobile; in sandy soil, the leaching percentage of CPF-MC was higher than that of CPF-EC.

Summary: The changes in physicochemical and biochemical parameters of vineyard soils after adding spent mushroom substrate (SMS) or composted SMS with ophite (OF) were investigated. The results showed that soil organic carbon and nutrient levels increased, especially with the highest SMS dose. The addition of SMS or SMS + OF led to increased dehydrogenase activity, respiration, and microbial biomass. The composition of phospholipid fatty acids (PLFAs) also reflected the changes in microbial community. The study suggests that the application of SMS or SMS + OF can be an effective agronomic practice for soil sustainability.

Summary: The persistence of fluopyram and tebuconazole in different crops and agricultural soils has been studied. However, the behavior of these fungicides may change when they are applied as a combined formulation in organically amended vineyard soils under field conditions. This study evaluates the effect of applying spent mushroom substrate (SMS) or this residue re-composted with ophite (SMS + OF) on the adsorption, dissipation, and mobility of fluopyram and tebuconazole in vineyard soils. The results indicate different dissipation mechanisms for both fungicides, as the adsorption by soil organic carbon prevented the dissipation of fluopyram but facilitated the dissipation of tebuconazole, probably due to the formation of non-extractable residues.

Summary: The application of organic residues as soil organic amendments is considered a sustainable option to solve the problem of uncontrolled waste accumulation, improve soil quality, and avoid irreversible degradation. However, the behavior of pesticides in soil can be affected by the presence of organic residues. Laboratory studies have shown that different factors related to organic residues, pesticides, and soil properties can influence processes such as adsorption-desorption, dissipation, and leaching of pesticides in soil. Future research is needed to extend these findings to field and modeling scales for a better assessment and prediction of pesticide fate in amended soil scenarios.
