Although pesticides undergo degradation tests prior to use, determining their export,
degradation and persistence under field conditions remains a challenge for water resource
management. Compound specific isotope analysis (CSIA) can provide evidence of
contaminant degradation extent, as it is generally independent of non-destructive dissipation
(eg, dilution, sorption, volatilization) regulating environmental concentrations. While this
approach has been successfully implemented in subsurface environments, its application to …

Pesticides in the environment is a worldwide issue of increasing concern. Determining
pesticide fate in the field remains a challenge that may preclude adapted risk assessment
and water resource management. Application of compound-specific isotope analysis (CSIA)
to evaluate degradation of diffuse and low-concentration pesticides in surface hydrological
contexts is mostly recent. Compound-specific isotope analysis (CSIA) can provide evidence
of contaminant degradation extent, as it is generally independent of non-destructive …
