A kapott adatok szerint \u00e9vente 74 tonna mikrom\u0171anyag sodr\u00f3dik Auckland leveg\u0151j\u00e9ben, ami 3 milli\u00f3 m\u0171anyag palackkal \u00f6sszem\u00e9rhet\u0151.<\/p>\n
A kimutatott mikroszemcs\u00e9k f\u0151k\u00e9nt polietil\u00e9n (PE), polikarbon\u00e1t (PC) \u00e9s polietil\u00e9n-tereftal\u00e1t (PET). Ezeket az anyagokat a csomagol\u00e1sban, az elektronik\u00e1ban \u00e9s az \u00e9p\u00edt\u0151iparban haszn\u00e1lj\u00e1k.<\/p>\n

Figyelemre m\u00e9lt\u00f3, hogy a legkisebb r\u00e9szecsk\u00e9k voltak a legnagyobb mennyis\u00e9gben jelen. Ez aggaszt\u00f3 jel, mivel a nanoplasztik\u00e1k k\u00fcl\u00f6n\u00f6sen vesz\u00e9lyesek az eg\u00e9szs\u00e9gre, mivel k\u00f6nnyebben behatolnak a sejtekbe, majd felhalmoz\u00f3dnak a szervekben, bele\u00e9rtve az agyat is.<\/p>\n
A tud\u00f3sok szerint a tanulm\u00e1ny volt az els\u0151, amely kimutatta a v\u00e1rosi leveg\u0151ben l\u00e9v\u0151 mikrom\u0171anyagok teljes t\u00f6meg\u00e9t. Azt is meg\u00e1llap\u00edtott\u00e1k, hogy a mikror\u00e9szecsk\u00e9k l\u00e9gk\u00f6rbe jut\u00e1s\u00e1t el\u0151seg\u00edtheti a sz\u00f6rf\u00f6z\u00e9s. Az Auckland partjait mos\u00f3 \u00f6b\u00f6lben a sz\u00e9l feler\u0151s\u00f6d\u00e9sekor magas koncentr\u00e1ci\u00f3j\u00fa szennyez\u00e9st tapasztaltak.<\/p>\n","protected":false},"excerpt":{"rendered":"
