Procena ekološkog rizika usled prisustva organskih UV filtera u vodi i sedimentima

Abstract

Glavni sastojci proizvoda za zaštitu kože od UV zračenja jesu UV filteri. U poslednjih nekoliko godina, organski UV filteri izazvali su značajnu zabrinutost zbog stalnog korišćenja, upornog unosa i potencijalne pretnje ekološkom okruženju i ljudskom zdravlju. Mnogobrojne studije upozoravaju na stabilnost, bioakumulativnost, kao i toksične efekte ovih jedinjenja na akvatične organizme. Procena ekološkog rizika usled prisustva odabranih UV filtera u vodi i sedimentima je vršena na osnovu podataka iz literature vezanih za rezultate monitoringa ovih supstanci, kao i na osnovu podataka o njihovoj toksičnosti po vodene organizme. Najviše koncentracije odabranih organskih UV filtera detektovane su u otpadnim vodama, kao i na mestima ispusta otpadne vode u recipijent. Procena rizika je pokazala da ova jedinjenja predstavljaju potencijalnu pretnju za organizme koji žive u vodenoj sredini. Analizom podataka sa većeg broja lokacija utvrđen je visok ekološki rizik usled prisustva pojedinih UV filtera u vodenoj sredini, i pokazano da su posebno ugrožene lokacije u blizini ispusta otpadnih voda.

The main ingredients of skin protection products from UV radiation are UV filters. In the last few years, organic UV filters have caused significant concern due to constant use, persistent intake, and potential threats to the environment and human health. Numerous studies warn of the stability, bioaccumulation, as well as toxic effects of these compounds on aquatic organisms. The environmental risk assessment of UV filters was performed based on data from the literature related to the results of monitoring of these substances in water and sediments, as well as based on data on their toxicity to aquatic organisms. The highest concentrations of selected organic UV filters were detected in wastewater, as well as at the points of wastewater discharge into the recipient. Risk assessment has shown that these compounds pose a potential threat to aquatic organisms. The analysis of data from several locations determined a high environmental risk due to the presence of certain UV filters in the aquatic environment and showed that the locations near the wastewater discharge are particularly endangered.
