Multi-elemental compound-specific isotope analysis of pesticides for source identification and monitoring of degradation in soil: a review

Patrick Hohener et al.

Summary: The transfer of pesticides from agricultural soils to food and drinking water is a major health concern. This review focuses on the use of multi-elemental compound-specific isotope analysis to study the sources and transformations of pesticides in agricultural soils. Advanced extraction and purification techniques as well as analytical techniques for measuring stable isotope composition of pesticides are discussed. A unique dataset of isotopic compositions of various pesticides and isotope fractionation values for different compounds is reported, providing insights into the mechanisms of pesticide transformation.

Uptake of Soil-Residual Diazinon by Rotational Lettuce under Greenhouse Conditions

Jihyun Yoon et al.

Summary: Pesticide residue in rotational crops, such as lettuce, is a growing concern. This study investigated the residue pattern of diazinon in lettuce and found that the uptake ratio from soil to plant ranged from 0.002 to 0.026 over the harvest period. The residue in the edible leaf could exceed the acceptable level if lettuce is rotated in soil with high diazinon content.

The carbon stable isotope compositions of glyphosate and aminomethylphosphonic acid (AMPA): Improved analytical sensitivity and first application to environmental water matrices

A. Williams Limon et al.

Summary: The study aimed to improve the sensitivity of delta C-13 analysis of glyphosate and AMPA, and demonstrate their measurability in natural surface water. LC/IRMS technology showed improved analysis results, and a freeze-drying pre-concentration method was successfully tested. Differentiation was needed in water samples, highlighting the feasibility of measuring these compounds in various hydrofacies.

Plants affect the dissipation and leaching of anilide pesticides in soil mesocosms: Insights from compound-specific isotope analysis (CSIA)

Paula Perez-Rodriguez et al.

Summary: The study found that leaching, dissipation, and degradation of pesticides in different types of soil mesocosms can be influenced by the planted or unplanted conditions, with planted mesocosms favoring pesticide degradation. Compound-specific stable isotope analysis showed that biodegradation of pesticides in soil-plant systems mainly occurred in the soil solution leached after rainfall events.

Persistence and metabolism of the diamide insecticide cyantraniliprole in tomato plants

Khang Huynh et al.

Summary: The plant uptake and metabolism of the insecticide cyantraniliprole was studied in tomato plants, revealing that mature leaves contained the highest residues, followed by flowers and immature fruits. Metabolism of cyantraniliprole primarily occurred in the foliage, with various metabolites identified in flowers and fruits. Major transformation pathways included ring closure, N-demethylation, and glycosylation, with additional minor phase-I, phase-II, and breakdown metabolites also observed. Overall, there was a tissue-specific accumulation of metabolites of cyantraniliprole in tomato plants.

Phase Transfer and Biodegradation of Pesticides in Water-Sediment Systems Explored by Compound-Specific Isotope Analysis and Conceptual Modeling

Boris Droz et al.

Summary: Current approaches are often limited to evaluating the contribution of pesticide dissipation processes in water-sediment systems. Compound-specific isotope analysis emphasized the importance of pesticide degradation in the water phase. Combining CSIA with high-resolution tandem mass spectrometry for the identification of transformation products can improve the interpretation of pesticide dissipation in water-sediment systems.
