THE EFFECT OF OZONATION BY- PRODUCTS ON HUMAN EMBRYONIC KIDNEY CELLS (HEK293): OZONE AS WASTEWATER TREATMENT TOOL
The occurrence of the pharmaceuticals and personal care products (PPCPs) is found daily in the wastewater stream since these micropollutant never removed by the conventional wastewater treatment. The daily accumulative of PPCPs in human and aquatic life can cause health and ge-netic damage, for that using an advanced oxidation treatment like ozone is necessary to remove the PPCPs from the water, the ozonation by-products have been studied to ensure the safety of using ozone as a polish step to remove the PPCPs from the water stream. This study shows the effect of the ozonation by-products on the human embryonic kidney cells HEK293 proliferation comparing with the control. Results shows that the ozonation by products are safe and most of the by-products are weak acids compounds that can be degraded in sun light and cell prolifera-tion reduction were no more than 10 % comparing with control, for that ozonation by-products are safe for human.
