Organic UV filters continuously accumulate after entering the environment, thus posing potential ecological and health risks. The impact of five organic UV filters, namely BP-3, BP-4, OC, EHMC, and BM-DBM, on the multixenobiotic resistance (MXR) mechanism in human embryonic lung fibroblasts (MRC-5) was investigated to identify the toxic effects of inhaled UV filters on human health. Results showed that OC exerted a more significant inhibitory effect on the transport proteins of MRC-5 cells than

BM-DBM exerted a significant inhibitory effect at exposure concentrations of 10 and 100µmol/L. The results of this study provide powerful scientific basis for the investigation of the impact of UV filters on the MXR mechanism of human cells at the molecular level.
