Apstrakt

Velika primena veštačkih zaslađivača kao aditiva u hrani, piću, lekovima i sredstvima za oralnu higijenu je dovela do akumuliranja ovih supstanci u akvatičnim ekosistemima širom sveta. Pošto je većina njih metabolički inertna i nepotpuno se uklanja u postrojenjima za prečišćavanje otpadnih voda, komunalne otpadne vode predstavljaju glavni izvor ovih jedinjenja u životnoj sredini. Njihovo ponašanje i uticaj na živi svet je uglavnom nepoznat, pa su svrstani u visoko prioritetne emergentne zagađujuće materije. Neki od njih, poput acesulfama i sukraloze, su veoma postojani u vodenoj sredini, pa se mogu koristiti kao markeri zagađenja komunalnim otpadnim vodama. U ovom radu je praćeno prisustvo najčešće korišćenih zaslađivača u Republici Srbiji (acesulfama, saharina, ciklamata, sukraloze i aspartama) u podzemnoj vodi iz dva beogradska reni bunara, kao i u reci Savi, radi procene uticaja netretiranih komunalnih otpadnih voda na vodoizvorišta, pomoću metode tečne hromatografije sa tandem masenom spektrometrijom.
