Los nano y microplásticos son partículas de plástico de menos de 5 mm y 1 µm, respectivamente, que, al no degradarse, se acumulan en el medioambiente y son ingeridas por muchos organismos, incluido el ser humano.
Todavía se desconoce si estos contaminantes emergentes representan un riesgo sustancial para la salud humana. Un problema importante a la hora de determinar los riesgos de los nano/microplásticos para la salud humana es la falta de información sobre la exposición humana.
El agua de consumo es una ruta de exposición en humanos, pero pocos estudios han cuantificado las concentraciones de nano/microplásticos en las aguas de consumo.
La hipótesis de este estudio es que el agua embotellada contribuye más que el agua de grifo a la exposición a nano/microplásticos y aditivos plásticos. Llevaremos a cabo un estudio de intervención en el cual, las personas voluntarias alternarán su fuente de agua de consumo, entre agua del grifo y agua embotellada, cuatro veces durante aproximadamente ocho semanas.
Durante el seguimiento, las personas voluntarias recogerán varias muestras de heces y orina, en las que se medirán los niveles de nano/microplásticos y diferentes aditivos, incluyendo ftalatos, retardadores de llama polibromados y PFAS entre otros.
Los resultados que se obtengan de este estudio permitirán saber qué tipo de agua de consumo es la más adecuada si queremos reducir la exposición a nano/micropláticos.
