Plastic photodissolution into dissolved organic carbon (DOC) is a key proposed loss pathway for plastic in aquatic environments. However, the specific solar excitation wavelengths that drive remain unknown, limiting our ability to model and predict rates natural To better understand impact of wavelength on rates, we measured sensitivity variety transparent semitransparent commercial postconsumer films with wide-spanning polymer chemistries. We irradiated using custom-built light-emitting diode (LED) photoreactors emit light range 275 445 nm found plastics exhibit strong sensitivity, producing highest DOC release short ultraviolet (UV) light. additionally calculated quantum yield trends then activation spectra. UV between 300–350 responsible most all compositions predicted within water columns. Results advance
