Cytotoxicity and Genotoxicity toward Mammalian Cells Induced by Organic Iodine in Peroxymonosulfate (PMS) Processes: Activated PMS Is Better than Nonactivated PMS in Mitigating Toxicity

Peroxymonosulfate (PMS) and its activation processes have been extensively studied. However, iodinated byproducts (I-DBPs) generated during nonactivated PMS (NPMS) activated (APMS) pose a significant risk. In NPMS, 50 μg/L concentration of iodide (I–) could significantly (p < 0.05) increase the cytotoxicity both Suwanee River natural organic matter (SRNOM) solution wastewater secondary effluent (SE), at dose 0.5 mM PMS. Cytotoxicity genotoxicity SRNOM increased by 6.6 mg-phenol/L 2.4 μg-4-NQO/L with 200 I–. For toxicities 2.4-fold 1.9-fold. APMS reduced 42–47% 53–60% compared NPMS in I–-containing SE samples. promoted adsorbable iodine (AOI) formation, while inhibited AOI 77.5–84.9%. FTICR-MS showed favored I-DBP generation aromatic precursors, whereas eliminated these precursors I-DBPs. Compounds such as p-iodophenol 4-methyl-2-iodophenol were detected but removed APMS. exhibited weaker oxidation, producing tannic acid-like, lignin-like, protein-like that can toxicity when reacting HOI. Conversely, enhanced oxidation via hydroxyl radicals singlet oxygen, decomposing further. Importantly, also converted HOI into nontoxic iodate, reducing overall water.
