Abstract
Plastics are a fundamental part of everyday life due to their versatility and low cost. However, their waste is causing concern due to their accumulation in the marine-coastal environment. In order to compare the content of plastics in the sediments of two sectors of the San Luis beach (Sucre state), a sampling was carried out during the dry season. For this purpose, three 100 m transects were delimited, where 5 equidistant points were located for sample collection. The sediments were dried at room temperature, separated into granulometric fractions and observed with 10x magnifying glasses. The fine sediments and the coarse sediments already observed were then treated with a saturated NaCl solution to separate plastics by density. The plastics were classified according to their size, shape and color. The results indicated the presence of macro, meso and microplastics in all samples and a higher abundance of plastic particles in sector A, since sector B is more crowded and is subject to frequent cleaning due to the services it offers. Fragments and fibers were the most common forms, highlighting the influence of fishing and urban activities.
