Los científicos que tomaron muestras de nieve ártica aparentemente descubrieron altos niveles de microplásticos que probablemente fueron transportados al norte por la atmósfera.

Los astrónomos crearon un nuevo mapa tridimensional de la Vía Láctea. Revela que nuestra galaxia está deformada, con un disco estelar en forma de S.

Un investigador recoge una muestra de nieve en Bremen, Alemania. Los científicos del Instituto Alfred Wegener analizaron los microplásticos contenidos en la muestra. Entre las partículas que los investigadores detectaron estaban el barniz, diferentes tipos de caucho, polietileno y poliamida . Algunas muestras tenían sólo un par de tipos diferentes de polímero; otros tenían una docena.

Las partículas eran muy pequeñas, con un tamaño que oscilaba entre 475 micras y sólo 11 micras. Un 80% de esas partículas midieron 25 micrones o menos. Y a medida que las partículas se fueron haciendo más pequeñas, generalmente crecieron en número. Esto sugiere que puede haber muchas más partículas incluso más diminutas que el límite de detección de 11 micras de los científicos.

“El Ártico es un ecosistema increíblemente frágil que está bajo mucho estrés”, dijo. “Con el cambio climático, donde se derrite el hielo, es posible que haya más plásticos biodisponibles que cuando está encerrado en el hielo”.Esto significa que el plástico podría estar llegando a las cadenas alimenticias que incluyen comunidades inuit, dijo Rochman.
