Presencia de microplásticos en cuatro playas arenosas de Perú

Se presenta el numero y peso por metro cuadrado de fragmentos de microplasticos presentes en cuatro playas arenosas de la costa peruana. Las muestras fueron colectadas entre junio de 2014 y mayo 2015. Fragmentos de plastico duro mayores a 1 mm fueron encontrados en mas del 80% de las muestras de las cuatro playas. La playa Costa Azul (~ 12°S) presento 522 fragmentos por metro cuadrado (items/m2) de microplasticos, de los cuales, 463.33 items/m2 y 2.6 g/m2 fueron plasticos duros. La playa Albufera de Medio Mundo (~ 11°S) presento el menor numero y peso de microplasticos (4.67 items/m2 y 0.50 g/m2). Una muestra aleatoria de la playa Costa Azul fue analizada por el espectroscopio FT-IR. Se encontro 5 fragmentos con poliuretano (PE), dos fragmentos con polipropileno (PP) y un fragmento con estireno (EPS). Pocos estudios mencionan al plastico duro como la mayor fraccion de los microplasticos, se sugiere nuevas fuentes de intrusion y vias de microbasura en los habitas, los cuales podrian estar afectando desde la base de trama trofica marina en el Peru.
