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

A smaller sized amount of n-dodecane and additional hydrocarbons (e.g., undecane and tridecane) had been detected in samples irradiated to 2.0 MGy.
