Summary: The objective of this study was to evaluate the effectiveness of an automated extraction system for pesticide analyses in solid environmental samples. An Energized Dispersive Guided Extraction (EDGE) system was used to optimize the extraction of 210 pesticides and pesticide transformation products. The method showed comparable performance to the previously validated pressurized liquid extraction (PLE) method with slightly better sensitivities.

Summary: The dissipation experiment of Tiafenacil in citrus orchards showed that the herbicide readily dissipates in soil with a short half-life. The dissipation rate was positively correlated with soil organic matter content and negatively correlated with soil pH, while the influence of temperature and rainfall was minimal.

Summary: A GC-MS/MS method was developed to determine the dissipation and residue of MEZ in grapes and soil, and assess the dietary risk for Chinese people. The study found that the half-life of MEZ in grapes ranged from 11.75 to 20.39 days, and the overall risk assessment indicated that the risk of MEZ was acceptable. This study provides valuable reference for the detection and risk assessment of MEZ in other agricultural products.

Summary: The dissipation profiles of abamectin, hexythiazox, and spiromesifen in eggplant fruits were studied in Najran, Saudi Arabia. A 2-fold dilution of the sample extract effectively reduced interference and matrix effects. The method was successfully validated and the risk assessment showed no risk to human health. The study provides useful information for the safe use of acaricides on eggplant fruits.

Summary: A sensitive and rugged method using GC-MS/MS was developed for the simultaneous determination of 60 herbicides in aquatic products. Excellent linearity (1.0-100.0 μg/L) with R2 value of >= 0.9991 was achieved, and the limits of quantification ranged from 0.018 to 3.852 μg/kg. The method was successfully applied to analyze herbicide residues in actual aquatic products, and the risk assessment of dietary exposure was conducted. The findings highlight the need for monitoring herbicide residue levels in aquatic products to ensure consumer safety and maintain the quality of marine products.

Summary: This study uses GC-APCI-MS/MS to detect and identify 8 herbicide residues in plant-based foodstuffs. APCI, as a soft ionization technique, enhances sensitivity and selectivity by generating more molecular ions and/or protonated molecules. The method has a range of 0.5 to 50 ng/mL for calibration curves, with recoveries in the range of 76.3-108.5%. The limit of quantification for all samples is 1.0 μg/kg. The results demonstrate the potential of GC-APCI-MS/MS in routine detection and identification of herbicide residues in plant-based foodstuffs.

Summary: Fermentation of highland barley with different mushroom strains can change the aroma profile, reducing the grassy taste and acquiring new floral, sweet, and mushroom flavors. The flavor of the fermented highland barley varies with different mushroom strains, with Morchella esculenta showing the best performance. The study suggests that fermentation with mushroom mycelium can improve the flavor of highland barley, providing innovative utilization possibilities.

Summary: Slow pyrolysis of spruce and birch was conducted under different heating programs and conditions in a quartz tube reactor heated by an electric furnace. The study found that spruce produced more char yield than birch, and the main gaseous products showed similar evolution profiles. The relative amount of aromatic and polyaromatic compounds in volatile matter decreased significantly with increasing carbonization temperature.

Summary: An efficient method was established for simultaneously determining PYR and its metabolite BF 500-3 in cucumber fruits, leaves, and soil matrices, showing that PYR quickly dissipates in cucumber fields and does not exceed the maximum residue limit in cucumber fruits at the recommended application rate of 150 g a.i. ha(-1) in China.

Summary: A new multi-residue method using gas chromatography-mass spectrometry electron ionization selective ion monitoring mode (SIM) has been developed for the simultaneous determination of eight 1,3,5-triazine herbicides in water and soil samples. The method was applied for the determination of residues in groundwater and soil samples. The lowest detection limit by GC-MS-SIM is 0.1 pg/mL, and the recovery rates in water and soil samples are in the range of 93-103% and 91-102% respectively for different individual compounds.

Summary: A rapid, highly selective, reusable and effective method was developed for simultaneous determination of alachlor, acetochlor and pretilachlor in field soil by GC-MS coupled with MIL-101 based SPE. MIL-101(Cr) exhibited excellent adsorption performance for amide herbicides. The method validation showed good linearities, low limits of detection, high enrichment factors, matrix effect within acceptable range, satisfactory recoveries, and low RSD. The developed method successfully detected amide herbicides in soil samples from different depths, showing a decreasing trend with increasing depth. This finding provides a novel method for the detection of amide herbicides in agriculture and food industry.

Summary: Soil is a major recipient of contaminants, including organochlorine pesticides, despite being banned in the EU. A GC-MS/MS method was developed and applied to soil samples, revealing the presence of dieldrin. The subsequent health risk assessment showed negligible non-carcinogenic risk and tolerable carcinogenic risk, indicating the importance of continuous monitoring for persistent chemical residues in soil.

Summary: This study reports the levels and distribution of polychlorinated biphenyls (PCBs) in residential soils in East Chicago, Indiana. The PCB concentrations were found to be relatively high and influenced by nearby contamination sites. The concentrations increased with the total organic carbon content and proximity to the contaminated area. Despite the higher concentrations compared to other locations, the samples were still below the current soil remediation goal.

Summary: This study investigated the co-combustion of aboveground and belowground biomass of Pfaffia glomerata with pulverized coal. The results showed that the mixtures of 30% aboveground biomass and 70% coal and 10% belowground biomass and 90% coal exhibited the strongest co-combustion synergy, reducing dependence on fossil fuels and stabilizing heavy metals in ash.
