Presencia de microplásticos en cuatro playas arenosas de Perú
AI summary Read the abstract
Microplastic fragments were found on four sandy beaches along the Peruvian coast, with the most contaminated beach having over 500 fragments per square meter. The findings document microplastic contamination in South American Pacific coastal environments where little prior data existed.
Se presenta el número y peso por metro cuadrado de fragmentos de microplásticos presentes en cuatro playas arenosas de la costa peruana. Las muestras fueron colectadas entre junio de 2014 y mayo 2015. Fragmentos de plástico duro mayores a 1 mm fueron encontrados en más del 80% de las muestras de las cuatro playas. La playa Costa Azul (~ 12°S) presentó 522 fragmentos por metro cuadrado (items/m2) de microplásticos, de los cuales, 463.33 items/m2 y 2.6 g/m2 fueron plásticos duros. La playa Albúfera de Medio Mundo (~ 11°S) presentó el menor número y peso de microplásticos (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 encontró 5 fragmentos con poliuretano (PE), dos fragmentos con polipropileno (PP) y un fragmento con estireno (EPS). Pocos estudios mencionan al plástico duro como la mayor fracción de los microplásticos, se sugiere nuevas fuentes de intrusión y vías de microbasura en los hábitas, los cuales podrían estar afectando desde la base de trama trófica marina en el Perú.
