Arnika v pr\u016fb\u011bhu studie, na kterou obdr\u017eela od magistr\u00e1tu dotaci 250.000 korun, provedla m\u011b\u0159en\u00ed v 52 budov\u00e1ch v Praze. Polovinu z nich tvo\u0159ily dom\u00e1cnosti a polovinu ve\u0159ejn\u00e9 objekty, jako jsou radnice \u010di \u0161koly.

Na hodnoty v budov\u00e1ch neexistuj\u00ed v \u010desk\u00e9 legislativ\u011b \u017e\u00e1dn\u00e9 limity, Arnika proto koncentraci t\u011b\u017ek\u00fdch kov\u016f srovnala s normami pro d\u011btsk\u00e1 p\u00edskovi\u0161t\u011b, kter\u00e9 jsou nejp\u0159\u00edsn\u011bj\u0161\u00ed.

V p\u0159\u00edpad\u011b rtuti \u0161lo o 34,6 procenta dom\u00e1cnost\u00ed a 46,2 procenta ve\u0159ejn\u011b p\u0159\u00edstupn\u00fdch objekt\u016f.

Podle v\u00fdsledk\u016f anal\u00fdzy, kterou zpracovali v\u00fdzkumn\u00edci z Vysok\u00e9 \u0161koly chemicko-technologick\u00e9, nen\u00ed \u017e\u00e1dn\u00e1 p\u0159\u00edm\u00e1 vazba na bl\u00edzkost vn\u011bj\u0161\u00edch zdroj\u016f zne\u010di\u0161t\u011bn\u00ed a p\u0159\u00edtomnost t\u011b\u017ek\u00fdch kov\u016f. Brabcov\u00e1 z toho usuzuje, \u017ee hlavn\u00edm zdrojem zne\u010di\u0161t\u011bn\u00ed je vnit\u0159n\u00ed vybaven\u00ed budov.

V mezin\u00e1rodn\u00edm srovn\u00e1n\u00ed Praha podle Brabcov\u00e9 nedopadla \u0161patn\u011b. Nap\u0159\u00edklad v\u00fdsledky m\u011b\u0159en\u00ed v Ottaw\u011b byly o n\u011bco hor\u0161\u00ed.

„V p\u0159\u00edpad\u011b, \u017ee bude m\u011bsto vym\u011b\u0148ovat za\u0159\u00edzen\u00ed, budeme popt\u00e1vat jenom takov\u00e9 produkty, kter\u00e9 budou deklarovat materi\u00e1ly bez toxick\u00fdch l\u00e1tek,“ uvedla Kol\u00ednsk\u00e1 s t\u00edm, \u017ee Praha si takovou podm\u00ednku m\u016f\u017ee d\u00e1t do zad\u00e1vac\u00edch podm\u00ednek.

Podle Brabcov\u00e9 je d\u016fle\u017eit\u00e9, aby v\u00fdrobci p\u0159i v\u00fdrob\u011b materi\u00e1l\u016f toxick\u00e9 kovy nepou\u017e\u00edvali.
