Does the reuse of PET bottles during solar water disinfection pose a health risk due to the migration of plasticisers and other chemicals into the water?

Solar water disinfection (SODIS) is a low-cost method used in developing countries, treating water using sunlight in polyethylene terephthalate (PET) bottles for 6 hours. Concerns arose about chemical release from PET. This study assessed the transfer of substances from PET to water under SODIS conditions. Results indicated low concentrations of potentially harmful chemicals, with the SODIS procedure deemed safe regarding human exposure to these substances.
