Figure 6. (A) ACE and (B) Shannon index of biofilms on the photoaged PLA and PP MPs under microcosm incubation in surface water. ^*P < 0.05, ^**P < 0.01, and ^***P < 0.001. NS indicates no significant difference. ACE: Abundance-based eoverage estimator; PLA: polylactic acid; PP: polypropylene; MPs: microplastics.
