A F\u00f6ldk\u00f6zi-tenger a m\u0171anyagszennyezetts\u00e9g g\u00f3cpontj\u00e1nak sz\u00e1m\u00edt a Kosztasz Ciarasz vezette kutat\u00f3csoport szerint, mivel sok partszakasz s\u0171r\u0171n lakott. Ehhez j\u00e1rulnak m\u00e9g hozz\u00e1 olyan t\u00e9nyez\u0151k, mint a turizmus, a hal\u00e1szat, a haj\u00f3z\u00e1s \u00e9s nem utols\u00f3sorban a beltenger geogr\u00e1fi\u00e1ja is, hiszen viszonylag kis m\u00e9rt\u00e9k\u0171 a F\u00f6ldk\u00f6zi-tenger \u00e9s az Atlanti-\u00f3ce\u00e1n k\u00f6z\u00f6tti v\u00edzcsere.<\/p>\n\n\n\n

Egy \u00faj sz\u00e1m\u00edt\u00e1si modell szerint a tud\u00f3sok arra jutottak, hogy \u00e9vente mintegy 17 600 tonna m\u0171anyag landol a F\u00f6ldk\u00f6zi-tengerben, ebb\u0151l 3760 tonn\u00e1nyi lebeg a felsz\u00ednen, 2800 tonn\u00e1nyi les\u00fcllyed, a t\u00f6bbi r\u00e9sze pedig a partra mos\u00f3dik.<\/p>\n\n\n\n

Vil\u00e1gszerte t\u00f6bb mint 250 ezer tonn\u00e1nyi m\u0171anyag szem\u00e9t lebeg az \u00f3ce\u00e1nok felsz\u00edn\u00e9n. “A m\u0171anyag tengeri eloszl\u00e1s\u00e1t vizsg\u00e1l\u00f3 szimul\u00e1ci\u00f3kat jelenleg nagym\u00e9rt\u00e9k\u0171 bizonytalans\u00e1g jellemzi” – mondta el Ciarasz.

Egyeseket elnyelnek a tengeri \u00e1llatok, organizmusok, m\u00e1sok apr\u00f3 r\u00e9szekre esnek sz\u00e9t. Ehhez j\u00f6n m\u00e9g a sz\u00e9l, a hull\u00e1mok, az \u00e1ramlatok ereje, amely a m\u0171anyagot messzire hajtja.
A tud\u00f3sok ezeket a t\u00e9nyez\u0151ket mind figyelembe vett\u00e9k. Ez alapj\u00e1n t\u00f6bbek k\u00f6z\u00f6tt meghat\u00e1rozt\u00e1k azokat a r\u00e9gi\u00f3kat, ahol k\u00fcl\u00f6n\u00f6sen sok m\u0171anyag ker\u00fcl a tengerbe.<\/p>\n\n\n\n
