- Accumulation, origin, and chemical composition of Microplastics (MPs) found in beaches is still unknown for southeastern Mexico therefore there is a need to understand their presence. This paper is focused in identify and determine the abundance of MPs, as well as of chemical composition of their polymers, as a first approximation of the impact of MPs. Results showed that fibers are the most abundant MPs and the most common color was the blue/black, for particle, films and foams the most abundant color was transparent. Raman technique, the detected MPs with diameter of 0.1¿5 mm mainly composed of PE and PP. There were also some MPs unidentified, due to the multiple vibration modes that induced more than 10 Raman bands within each type of microplastic. The abundance of MPs in this area could be related to a bad deposition of plastic debris by local communities and also by the influence of marine trash. © 2025 Elsevier B.V.
