Abstract

Sve veća zabrinutost zbog nepovoljnog uticaja ultraljubičastog zračenja naljudsko zdravlje, dovela je do povećane upotrebe kozmetičkih preparata koji kao glavnesastojke sadrže UV filtre, supstance sposobne da apsorbuju, reflektuju i/ili raspršujufotone svetlosti i na taj način pružaju zaštitu od štetnog UV zračenja. Povećana upotrebaUV filtera ima sve veći uticaj na životnu sredinu. Iako su ova jedinjenja stabilna poddejstvom UV zračenja, pod određenim uslovima može doći do njihove razgradnje,uglavnom fotolizom ili u reakciji sa sredstvima na bazi hlora, kakva se obično koriste zadezinfekciju bazenskih voda...

Growing concern over deleterious effects of ultraviolet (UV) radiation onhumans has caused an increase in usage of sunscreen products with UV filter-containingformulations. UV filters are substances capable of absorbing, reflecting and/orscattering sunlight wavelengths, reducing the damage that this radiation might cause onhuman health. Increased application of sunscreen raised the concern regarding theirpossible environmental pathway, fate and effects. Although UV filters must be stable onexposure to UV light, under certain special conditions they might decompose by light ormay react with chlorine-based disinfection agents...
