With the purpose of determining densities of suspended microplastics on El Salvador marine coastal zones and compare them between 2018-2019, rainy and dry seasons, respectively, we performed samplings using a manta trawl complex with a 40-μm pore net on straight surface transects in front of El Pimental and Mizata beaches, La Libertad coastal city as well as gulf of Fonseca. The filtered material was preserved in ethanol 90 % V/V. Highest densities occurred in the last area (0.07-0.22 particles/m3), the contrary occurred in the third one (0.00-0.02 particles/m3). Comparison of microplastic densities from four sampling areas between rainy
and dry seasons showed significant difference (p<0.05), whose density averages were 0.08 + 0.06 y 0.03 + 0.04 particles/m3, respectively. The current preliminary study aims to determine basic information about microplastics abundance on near shore marine surface water in El Salvador.
