Photo aging of polypropylene microplastics in estuary water and coastal seawater: Important role of chlorine ion

•Photo aging of PP MPs was inhibited in seawater than in ultrapure water.•Cl- was the primary contributor to the inhibitory effect of PP MPs in seawater.•O2•- rather than •OH was responsible for the photo aging of PP MPs in seawater.•Light produced Cl2•- in seawater could quench HO2• and impend PP a...
