      Sport Fish Stomachs.

AB  - Microplastics were extracted from freshwater sport fish stomachs containing 
      substantial biomass and identified using optical microscopy, scanning electron 
      microscopy plus energy-dispersive X-ray spectroscopy (SEM/EDS), and Fourier 
      transform infrared (FTIR) micro-spectroscopy with automated spectral mapping. An 
      extraction method is presented that uses a negatively pressurized sieve stack and 
      purified water to preserve plastic surface characteristics and any adsorbed 
      persistent organic pollutants (POPs). This nondestructive extraction method for 
      large predators' stomachs enables multiple trophic-level studies from one fish 
      sampling event and provides other dietary and behavioral data. FTIR-identified 
      microplastics 50-1500 mum, including polyethylene (two with plastic additive 
      POPs), styrene acrylonitrile, polystyrene, and nylon and polyethylene 
      terephthalate fibers 10-50 mum wide. SEM/EDS revealed characteristic surface 
      weathering on the plastic surfaces. The nylon fibers appear to be from human 
      fishing activities, suggesting options for management. Some particles visually 
      identified as potential plastics were revealed by micro-spectroscopy to be 
      mineralized, natural polyamide proteins, or nonplastic shell pieces. A low-cost, 
      reflective sample preparation method with stable particle mounting was developed 
      to enable automated mapping, improved FTIR throughput, and lower detection size 
      limit. This study yielded 37 intact prey items set aside for future analyses.
