Fig. 8From: Distribution and characteristics of microplastics in beach sand near the outlet of a major reservoir in north Mississippi, USAComposition of polymers detected in: Aย upper wrack zone (>โ1ย mm); Bย upper wrack zone (<โ1ย mm); Cย lower wrack zone (>โ1ย mm); Dย lower wrack zone (<โ1ย mm); and Eย all samples combined. Polymers were identified using ยต-FTIR. Note: the percentage of polyamide (PA) may be underestimated as the samples were dried near the glass transition temperature which may affect detection of the polymer by FTIRBack to article page
