Sobre IBD

Ocena wód powierzchniowych pod kątem zawartości metali ciężkich jest tematem budzącym duże zainteresowanie, zarówno ze względu na znaczenie dla środowiska, jak i społeczne. Niniejsza praca ma na celu analizę próbek wody z rzeki Grajaú, położonej w stanie Maranhão, pod kątem zawartości miedzi, w celu oceny ewentualnego wpływu na środowisko. W tym celu pobrano sześć próbek wody z rzeki Grajaú w różnych punktach poboru, a oznaczenie ilościowe metalu przeprowadzono metodą spektrometrii absorpcji atomowej z piecem grafitowym. Wyniki wykazały zawartość miedzi w tych próbkach na poziomie od 0,01 do 0,08 mg L-1. Stężenia miedzi w próbkach wody przekroczyły maksymalne limity ustalone dla wody rzecznej klasy 3, zgodnie z uchwałą 357/2005 Krajowej Rady ds. Środowiska (CONAMA). Najwyższe stężenia odnotowano w obszarach chaotycznej zabudowy mieszkaniowej i ścieków bytowych.
