However, the disinfection efficacies of UV-A or -B in terms of inactivating waterborne viruses such as norovirus have not been characterized. We evaluated the inactivation kinetics of MS2 bacteriophage and murine norovirus (MNV), a surrogate of human norovirus (NoV), by UV-A and -B. In addition to UV disinfection, we further investigated whether the presence of TiO2 could enhance the virus inactivation kinetics of UV-A and -B. Both MS2 and MNV were highly resistant to UV-A. However, the addition of TiO2 enhanced the efficacy of UV-A for inactivating these viruses. UV-A dose of 1379 mJ/cm(2) resulted in a 4 log10 reduction. In comparison, UV-B alone effectively inactivated both MS2 and MNV, as evidenced by the 4 log10 reduction by 367 mJ/cm(2) of UV-B. The addition of TiO2 increased the inactivation of MS2; however, it did not significantly increase the efficacy of UV-B disinfection for inactivating MNV. When these treatments were applied to field water such as groundwater, the results were generally consistent with the laboratory findings. Our results clearly indicated that UV-B is useful for the disinfection of waterborne norovirus. However, MNV was quite resistant to UV-A, and UV-A effectively inactivated the tested viruses only when used in combination with TiO2.","is_dataset_classified":null,"base_score":3.9889840465642745,"endowment":3.9889840465642745,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"23871257","pmcid":null,"openalex_id":"https://openalex.org/W2029738612","authors":[],"funders":[{"funder_name":"Ministry of Education, Science and Technology","grant_id":"2012-0008692","title":null},{"funder_name":"Ministry of Education, Science and Technology","grant_id":"2012-0009628","title":null},{"funder_name":"National Research Foundation of Korea","grant_id":"","title":null}],"total_grants":3,"fwci":2.5369,"citation_percentile":0.89302628,"influential_citations":0,"citation_trend":[{"year":2013,"count":1},{"year":2015,"count":10},{"year":2016,"count":4},{"year":2017,"count":8},{"year":2018,"count":5},{"year":2019,"count":1},{"year":2020,"count":6},{"year":2021,"count":3},{"year":2022,"count":5},{"year":2023,"count":1},{"year":2024,"count":5},{"year":2025,"count":3},{"year":2026,"count":1}],"oa_status":"closed","license":"https://www.elsevier.com/legal/tdmrep-license","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0043135413005265?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0043135413005265?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.watres.2013.06.035","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/23871257","host_type":"repository"}],"fields_of_study":["Viral gastroenteritis research and epidemiology"],"mesh_terms":["Bacteriophages","Disinfection","Kinetics","Titanium","Ultraviolet Rays","Norovirus"],"keywords":["Murine norovirus","Norovirus","Bacteriophage MS2","Kinetics","Virus inactivation","Chemistry","Ultraviolet","Microbiology","Bacteriophage","Human decontamination","Virology","Food science","Virus","Biology","Escherichia coli","Biochemistry","Medicine","Materials science","Titanium dioxide","Ms2 Phage","Uv-a Inactivation","Uv-b Inactivation"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Clean water and sanitation"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-17T14:51:34.622866Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
