- •
UV–visible irradiation of thiophanate-methyl (TM) led to nine photoproducts.
- •
HPLC coupled with ultra-high resolution FTICR-MS allowed byproducts characterization.
- •
TM and one photoproduct were detected in peel and flesh of fruits treated with TM.
- •
In vitro tests showed that irradiation increases the global ecotoxicity of TM.
- •
In silico tests permitted to attribute the ecotoxicity enhancement to a photoproduct.
