Heterogeneity in susceptibility of viruses with different structures to various reactive oxygen species: Kinetics and biological mechanisms.

ABSTRACT: Waterborne viruses have caused outbreaks of related diseases and threaten human health, and advanced oxidation processes (AOPs), as clean and efficient technologies, have received widespread attention for their excellent performance in inactivating viruses. However, heterogeneity in susceptibility of structurally distinct viruses to various reactive oxygen species (ROS) is unclear. This study first measured the heterogeneity in inactivation kinetics and biological mechanisms of four typical viral surrogates (MS2, phi6, phix174, and T4) to various ROS by visible light catalysis. Notably, the second-order inactivation rate constants of four viruses by hydroxyl radicals (·OH), singlet oxygen (¹O₂), and superoxide radicals (·O₂ ^-) were quite differen
