All samples were extracted using solid-phase extraction methods at the Indian Institute of Technology (IIT) Delhi. Extracts were then transported to the University of Leeds for chemical analysis using liquid chromatography tandem mass spectrometry (LC-MS/MS). Analytical procedures followed adapted methods from Singh et al. (2019) to ensure comparability and reliability. Quality control measures—including method blanks, matrix spikes, and replicate analyses—were applied throughout to ensure data integrity.","metadataDate":"2026-06-27T13:28:14","notGEMINI":true,"pointsOfContact":[{"displayName":"Laura Carter","organisationName":"University of Leeds","organisationIdentifier":"https://ror.org/024mrxd33","role":"pointOfContact","email":"l.j.carter@leeds.ac.uk","fullName":"Laura Carter","pointOfContact":"University of Leeds"}],"publicationDate":"2025-11-12T00:00:00.000Z","publishers":[{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"resourceIdentifiers":[{"code":"https://catalogue.ceh.ac.uk/id/1a4588b8-7145-49ce-8bd5-0895d385932d"},{"code":"10.5285/1a4588b8-7145-49ce-8bd5-0895d385932d","codeSpace":"doi"}],"resourceType":{"value":"dataset"},"responsibleParties":[{"displayName":"Laura Carter","organisationName":"University of Leeds","organisationIdentifier":"https://ror.org/024mrxd33","role":"pointOfContact","email":"l.j.carter@leeds.ac.uk","fullName":"Laura Carter","pointOfContact":"University of Leeds"},{"honorificPrefix":"Professor","familyName":"Carter","givenName":"Laura","organisationName":"University of Leeds","organisationIdentifier":"https://ror.org/024mrxd33","role":"author","email":"l.j.carter@leeds.ac.uk","fullName":"Carter, L."},{"honorificPrefix":"Professor","familyName":"Ahammad","givenName":"Shaikh Ziauddin ","organisationName":"Indian Institute of Technology Delhi","organisationIdentifier":"https://ror.org/049tgcd06","role":"author","email":"zia@iitd.ac.in","fullName":"Ahammad, S.Z."},{"honorificPrefix":"Dr","familyName":"Gupta","givenName":"Sonia","organisationName":"Indian Institute of Technology Delhi","organisationIdentifier":"https://ror.org/049tgcd06","role":"author","email":"soniagupta166@gmail.com","fullName":"Gupta, S."},{"honorificPrefix":"Mr","familyName":"Dahiya","givenName":"Anil Kumar","organisationName":"Indian Institute of Technology Delhi","organisationIdentifier":"https://ror.org/049tgcd06","role":"author","email":"anilkumardahiya@outlook.com","fullName":"Dahiya, A.K."},{"honorificPrefix":"Ms","familyName":"Haneef","givenName":"Mahenaz","organisationName":"Indian Institute of Technology Delhi","organisationIdentifier":"https://ror.org/049tgcd06","role":"author","email":"Mahenaz.Haneef@dbeb.iitd.ac.in","fullName":"Haneef, M."},{"honorificPrefix":"Professor","familyName":"Rizwanul Haq","givenName":"Qazi Mohd","organisationName":"Jamia Millia Islamia","organisationIdentifier":"https://ror.org/00pnhhv55","role":"author","email":"qhaque@jmi.ac.in","fullName":"Rizwanul Haq, Q.M."},{"honorificPrefix":"Professor","familyName":"Sareen","givenName":"Dipti","organisationName":"Panjab University","organisationIdentifier":"https://ror.org/04p2sbk06","role":"author","email":"dipti.sareen@gmail.com","fullName":"Sareen, D."},{"honorificPrefix":"Professor","familyName":"Chorpra","givenName":"Sidharth ","organisationName":"Central Drug Research Institute","organisationIdentifier":"https://ror.org/04t8qjg16","role":"author","email":"skchopra007@gmail.com","fullName":"Chorpra, S."},{"honorificPrefix":"Professor","familyName":"Ahmad","givenName":"Iqbal","organisationName":"Aligarh Muslim University","organisationIdentifier":"https://ror.org/03kw9gc02","role":"author","email":"ahmadiqbal8@yahoo.co.in","fullName":"Ahmad, I."},{"honorificPrefix":"Dr","familyName":"Chowdhury","givenName":"Kaniz","organisationName":"University of Leeds","organisationIdentifier":"https://ror.org/024mrxd33","role":"author","email":"kajorysu29@yahoo.com","fullName":"Chowdhury, K."},{"organisationName":"University of Leeds","organisationIdentifier":"https://ror.org/024mrxd33","role":"rightsHolder"},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"custodian","email":"info@eidc.ac.uk"},{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"rightsHolders":[{"organisationName":"University of Leeds","organisationIdentifier":"https://ror.org/024mrxd33","role":"rightsHolder"}],"spatialReferenceSystems":[{"code":"http://www.opengis.net/def/crs/EPSG/0/4326","title":"WGS 84"}],"spatialRepresentationTypes":["textTable"],"spatialResolutions":[{"distance":"100","uom":"urn:ogc:def:uom:EPSG::9001"}],"temporalExtents":[{"begin":"2022-05-01","end":"2023-06-30"}],"title":"Antibiotic pollution in surface water and wastewater from two catchments in India, May 2022 -
