Stability and toxicity of benzophenonetype uv filters and its transformation products in the presence of chlorine in an aqueous media

Sve veća zabrinutost zbog nepovoljnog uticaja ultraljubičastog zračenja na ljudsko zdravlje, dovela je do povećane upotrebe kozmetičkih preparata koji kao glavne sastojke sadrže UV filtre, supstance sposobne da apsorbuju, reflektuju i/ili raspršuju fotone svetlosti i na taj način pružaju zaštitu od štetnog UV zračenja. Povećana upotreba UV filtera ima sve veći uticaj na životnu sredinu. Iako su ova jedinjenja stabilna pod dejstvom UV zračenja, pod određenim uslovima može doći do njihove razgradnje, uglavnom fotolizom ili u reakciji sa sredstvima na bazi hlora, kakva se obično koriste za dezinfekciju bazenskih voda...Growing concern over deleterious effects of ultraviolet (UV) radiation on humans has caused an increase in usage of sunscreen products with UV filter-containing formulations. UV filters are substances capable of absorbing, reflecting and/or scattering sunlight wavelengths, reducing the damage that this radiation might cause on human health. Increased application of sunscreen raised the concern regarding their possible environmental pathway, fate and effects. Although UV filters must be stable on exposure to UV light, under certain special conditions they might decompose by light or may react with chlorine-based disinfection agents..
