- Abstract
In order to examine the relationship between grain size and microplastic amounts of beach sediments, samples taken from Muğla beaches (Palamutbükü, Datça, Marmaris and Akyaka) were first characterized in terms of grain size. Meso- and macroplastics were separated from the bulk sediment under a stereomicroscope, then microplastics were separated using low-density microplastic separation methods. The meso-macroplastic content determined in 1.2 kg beach sediment sampled from each location and the microplastic content determined in 50 g of the representative beach sediment are as follows: 11 mesomacro plastics, 56 microplastics in Palamutbükü sample, 13 meso-macroplastics, 33 microplastics in Datça sample, 13 meso-macroplastics, 143 microplastics in Marmaris sample, and 4 meso-macroplastics and 59 microplastics in Akyaka sample, respectively. Akyaka beach sediment of medium sand size, which has the smallest average grain size among the studied samples, are determined to have the lowest mesomacroplastic content. Datça beach sediment with an average grain size of fine gravel has the coarsest average grain size and the highest percentage of gravel and is the sample with the lowest microplastic content. As a result of the Fourier Transform Infrared Spectrometer analysis performed on plastics in the form of fibers and fragments, it was determined that the compositions of microplastics include cellulose, which is a natural polymer, and polyethylene and polypropylene, which are synthetic polymers. In this study, there is not any relationship established between sediment grain size and microplastic abundance. However, the minimum number of fibers among all low-density microplastics strengthened the possibility of weak hydrophobic interaction in the sediment-microplastic environment and therefore easy transportation of fibers by agents like wind, wave, etc.
