Similar compounds were also identified inside the comple2-tetradecanone mentary PE-salt water irradiations. These compounds, identified in the low irradiation 2-hexadecanone dose PE ater mixtures, suggest that PE microplastics do undergo scission reactions to some To far better simulate the of O2. This contrasts with all the reactivity from the PE microplastics extent within the absence behavior of PE microplastics in natural water situations, Lake exposed to higher radiationwas utilized as a solvent for analogous purified PE gamma irradiaMichigan (LM, USA) water doses, which predominantly undergo crosslinking reactions.Table 2.
