Eine neue internationale Studie unter Beteiligung der Universitäten Hamburg und Bremen belegt: Durch den drastischen Rückgang des Meereises in der Arktis im vergangenen Jahrzehnt wird verstärkt Brom freigesetzt - mit Folgen. Zum einen wird dabei Ozon abgebaut, zum anderen lagert sich giftiges Quecksilber in der arktischen Lebenswelt ab. Der Rückgang der Eisdecke im Arktischen Ozean ruft nämlich Interaktionen zwischen dem Salz im Meereis, frostigen Temperaturen und Sonnenlicht hervor. Das salzige Eis setzt dadurch vermehrt Brom frei und startet eine Kette chemischer Reaktionen, "Bromexplosion" genannt, die zu immer mehr Brommolekülen in der Atmosphäre führt. Brom reagiert dann mit einer gasartigen Form dvg Hoditczadfa ndg hayifjvknu ug ol cvlwk Zdqdjpphhg, wfc phj pqr Jxexnrldxwfmk cugsh.
