The data was generated from a 20-week laboratory experiment designed to evaluate artificial degradation methods for plastic mulch films.\nThe dataset comprises observations from four artificial degradation methods-heat treatment and ultraviolet irradiation (UVA and UVC at two intensities)-applied to plastic mulch films over a period of approximately five months. These treatments were assessed against field-aged samples exposed under natural conditions for six months, enabling comparison of degradation rate, efficiency, and similarity to environmental weathering.\nData were collected using a combination of laboratory analytical techniques and physical measurements. Chemical changes were characterised using attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy to derive carbonyl indices, as well as differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Physical properties were assessed through measurements of film thickness and surface roughness. The dataset provides a structured comparison of degradation responses across different methods, polymer types, and analytical parameters.\nFurther details on experimental design, methodologies, and data processing are provided in the lineage field and the supporting documentation.","distributionFormats":[{"name":"Comma-separated values (CSV)","type":"text/csv","version":"unknown"}],"distributorContacts":[{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"distributor","email":"info@eidc.ac.uk"}],"funding":[{"funderName":"Natural Environment Research Council","funderIdentifier":"https://ror.org/02b5d8509","awardNumber":"NE/V005871/1","orcid":false,"ror":true}],"hasOnlineServiceAgreement":true,"id":"f595a53b-de36-4cff-b92a-33872b4c0622","incomingCitationCount":0,"infoLinks":[{"url":"https://data-package.ceh.ac.uk/sd/f595a53b-de36-4cff-b92a-33872b4c0622.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"inspireThemes":[{"theme":"Agricultural and Aquaculture Facilities","uri":"http://inspire.ec.europa.eu/theme/af"}],"keywordsOther":[{"value":"agricultural pollution","uri":"http://www.eionet.europa.eu/gemet/concept/216"},{"value":"chemical degradation","uri":"http://www.eionet.europa.eu/gemet/concept/11781"},{"value":"mulch","uri":"http://www.eionet.europa.eu/gemet/concept/5418"},{"value":"plastic","uri":"http://www.eionet.europa.eu/gemet/concept/6329"}],"keywordsTheme":[{"value":"Agriculture","uri":"http://onto.nerc.ac.uk/CEHMD/topic/1"},{"value":"Pollution","uri":"http://onto.nerc.ac.uk/CEHMD/topic/15"}],"licences":[{"value":"This resource is available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"}],"lineage":"-\tFilm thickness: Measured with a thickness gauge.
