Effect of lithological properties of beach sediments on plastic pollution in Bodrum Peninsula (SW Türkiye)

The effects grain size on transport and retention of plastics in sediments are controversial issue. Four beaches were selected on the Bodrum Peninsula (SW Türkiye) for this study. Twenty-four samples with poorly to well sorted, sandy gravel, gravel, or gravelly sand were collected from the top five...

Description
Summary:The effects grain size on transport and retention of plastics in sediments are controversial issue. Four beaches were selected on the Bodrum Peninsula (SW Türkiye) for this study. Twenty-four samples with poorly to well sorted, sandy gravel, gravel, or gravelly sand were collected from the top five cm of the sampling quadrant's four corners and center of 1 m2 area, from shoreline and backshore. The highest plastic content (38 mesoplastics/600 g – 455 microplastics (MPs)/1200 g) was determined on the Bodrum Coast having the highest population. Polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polyethylene terephthalate (PET) and polyurethane (PU) were predominantly detected with Fourier Transform Infrared Spectroscopy (FTIR) analysis as MPs as a fragment and fiber. This study indicates the negative correlation between grain size and the number of MPs in coastal sediments. Anthropogenic activities are evaluated as a possible primary source of plastic pollution in the study area. [Display omitted] •Bodrum Beach has the highest meso- and microplastics in Bodrum Peninsula.•38 mesoplastic/600 g – 455 microplastic/1200 g were found in the Bodrum coast.•Plastic holding capacity of sediments decreases as the grain size increases.•The plastic content of shoreline samples is higher than the backshore samples.•MPs are mainly composed of PE, PP, PVC, PS, PET, PU.
