Compound-Specific Isotope Analyses to Investigate Pesticide Transformation in Soil and Water

This chapter provides an overview of approaches employed in tracking pesticide degradation within agricultural catchments, focusing on the existing challenges and burgeonic prospects afforded by pesticide compound-specific isotope analyses (CSIA). The discussion centers on the development of CSIA for low concentrations of pesticides in environmental matrices. Additionally, the chapter explores the viability of implementing pesticide CSIA in field applications for tasks such as for source apportionment, discerning transformation reactions, and quantifying the extent of degradation on a catchment scale.
