Abstract
Freoni, odnosno klorofluorougljici, su spojevi koji su zbog svojih karakteristika imali veliku primjenu u širokom spektru djelatnosti. Iako značajno ne utječu na čovjekovo zdravlje, pokazalo se da su iznimno opasni za ozonski omotač, a time i za organizme na Zemlji. Zbog stvaranja ozonskih rupa, freoni se smatraju indirektnim uzročnikom uništavanja mnogih vrsta organizama, bilo životinjskih bilo biljnih ili patogenih. Svojim djelovanjem također ne utječe direktno na njihovo izumiranje, već na uništavanje njihova staništa ili smanjenje hrane čime onemogućavaju njihovo daljnje obitavanje na nekom prostoru što uvelike utječe na cjelokupnu biosferu. Tako povišenjem temperature dolazi do topljenja ledenjaka na kojem žive polarni medvjedi ili se povećanjem količine UV zračenja uništava fitoplankton. Iako je najprije rečeno kako ovakvi spojevi nisu štetni za čovjeka, potvrđeni su neki slučajevi kod kojih se javio problem sa srcem pri većoj izloženosti ovim spojevima. S obzirom na cjelokupnu štetnost ovih spojeva, doneseni su mnogi zakoni i regulative kojima bi se smanjila njihova koncentracija u atmosferi i na taj način očuvao planet i njegov cjelokupni okoliš.
Abstract (english)
Freons, more precisely chlorofluorocarbons, are compounds which, due to their characteristics, have been widely used. Even though they do not significantly affect human health, it has been shown that they are extremely dangerous for the ozone layer, but also for other organisms on Earth. By creating ozone holes, freons are considered to be an indirect cause of the destruction of many types of organisms, whether animal, plant or pathogenic. By their action, they do not directly affect their extinction, but by destroying their habitat or reducing food, freons make it impossible for them to continue living in a certain area, which greatly affects the entire biosphere. A temperature increase leads to the glaciers melting on which polar bears live and increase of UV radiation destroys phytoplankton. Although it was initially said that such compounds are not harmful to humans, some cases of heart problems have been confirmed due to greater exposure to these compounds. Considering the overall harmfulness of these compounds, many laws and regulations were passed to reduce their concentration in the atmosphere and preserve the planet and its entire environment.
