Abstract

Cijanobakterije ili modrozelene alge su jednostanični prokariotski organizmi koji podnose ekstremne uvjete okoliša pa ih možemo pronaći na raznim staništima, ali najčešće obitavaju u slatkoj vodi. Pri cvjetanju vode odnosno razmnožavanju cijanobakterija troši se kisik, a u trenutku kada kisika nestane dolazi do odumiranja stanica cijanobakterija i oslobođenja cijanotoksina u okolnu vodu. Cijanotoksini mogu biti opasni za ljudsko zdravlje ako se oslobode u vodu koja se koristi za piće. Najčešći cijanotoksini su mikrocistini, cilindrospermopsini, anatoksini i saksitoksini koji mogu izazvati glavobolju, vrtoglavice, temperaturu te neke veće zdravstvene probleme. Da bi se očuvalo ljudsko zdravlje znanstvenici su osmislili metode za uklanjanje cijanotoksina iz vode za ljudsku potrošnju te ih djelimo ih na klasične i napredne metode. Klasične metode su koagulacija i flokulacija, filtracija, adsorpcija i dezinfekcija, a napredme metode su membranski procesi, UV zračenje, ultrazvuk, ozon, UV/H2O2 i O3/ H2O2.

Abstract (english)

Cyanobacterias or blue-green algae are prokaryotic organisms that can endure extreme enviromental conditions, so we can find them in various habitats, but usually they live in freshwater. When blooming in water (cyanobacterial blooming), the amount of oxygen is being reduced, in the moment when there is no more oxygen left, the cyanobacterial cells are starting to die and cyanotoxins are released to the surrounding water. If they are released in drinking water, cyanotoxins can be dangerous for human health. The greatest cyanotoxins that can cause headache, dizziness, fever or some more serious health problems are microcystins, cylindrospremopsin, anatoxin and saxitoxins. To preserve human health, the scientists have designed some methods for eliminating cynotoxins from the drinking water. We divide them into conventional and advanced methods. Conventional water treatment are coagulation and floccularion, filtration, adsorption and disinfection and advanced water treatment are membrane processes, ultraviolet, ultrasound, ozone, UV/H2O2 and O3/H2O2.
