By means of ECOSAR software, the formation of predominant more noxious TPs of epoxiconazole was proved than the parent compound for both acute and chronic toxicities. Instead, most TPs of coumarin and hymecromone generally exhibited \u201charmful\u201d and \u201ctoxic\u201d levels of acute and chronic toxicities.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>A probable structural identification was assigned to the monitored TPs via HPLC\u2010HRMS to recognize the several transformation pathways, of which the hydroxylation reaction was predominant, and which compound may be more hazardous in the aquatic system due to its TPs. Epoxiconazole transformation brought to potentially toxic TPs, whereas photoinduced degradation of coumarin and hymecromone resulted in less hazardous TPs. The most significant aspect of this work is the ability of this overall approach to identify the formation of photoinduced TPs that are potentially more toxic than the original CEC.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/rcm.10075","type":"journal-article","created":{"date-parts":[[2025,5,21]],"date-time":"2025-05-21T02:15:44Z","timestamp":1747793744000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Study of the Photoinduced Fate of Selected Contaminants in Surface Waters by HPLC\u2010HRMS"],"prefix":"10.1002","volume":"39","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4614-0768","authenticated-orcid":false,"given":"Rossella","family":"Sesia","sequence":"first","affiliation":[{"name":"Department of Management and Production Engineering Politecnico di Torino  Torino Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0726-3025","authenticated-orcid":false,"given":"Federica\u00a0Dal","family":"Bello","sequence":"additional","affiliation":[{"name":"Department of Molecular Biotechnology and Health Sciences University of Turin  Torino Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudio","family":"Medana","sequence":"additional","affiliation":[{"name":"Department of Molecular Biotechnology and Health Sciences University of Turin  Torino Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rita","family":"Binetti","sequence":"additional","affiliation":[{"name":"SMAT  Torino Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dimitra","family":"Papagiannaki","sequence":"additional","affiliation":[{"name":"SMAT  Torino Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5165-929X","authenticated-orcid":false,"given":"Paola","family":"Calza","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of Torino  Torino Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,5,20]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.talanta.2005.09.037"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2020.141990"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1039\/D4CY00474D"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-540-74664-5_1"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.iswcr.2015.03.002"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2014.08.035"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jphotochem.2016.12.008"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2020.143805"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.apcatb.2006.04.021"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/rcm.8925"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/rcm.5180"},{"key":"e_1_2_7_13_1","volume-title":"Aquatic and Surface Photochemistry","author":"Helz G.
