چکیده
Formy ťažkých kovov a ich vplyv na kvalitu vody v rieke Hornád Problém nahromadenia ťažkých kovov v životnom prostredí je jedným z najväčších problémov súčastnosti. Najviac ťažkých kovov pochádzajúcich z antropogénnej činnosti sa hromadí vo vodnom systéme, vďaka tomu sa ťažké kovy dostávajú cez potravinový reťazec do ľudského organizmu, pre ktorý sú vo zvýšených koncentráciách toxické. Z hľadiska toxického pôsobenia na organizmus je dôležité poznať nie len celkové množstvo kovového prvku, ktoré sa nachádza v recipiente, ale aj v akých formách je prvok viazaný. V práci bola navrhnutá metóda postupnej extrakcie, ktorá rozdeľuje jednotlivé formy kovov do 6 frakcií, čo umožňuje ich stanovenie.
