Samples were weighed and analysed for concentrations of the following elements: Mg, Al, V, Cr, Mn, Fe, Co, Ni, Cu. Zn,  As, Se, Mo, Cd, Sb, Ba and Pb. The data covered three seasons in Bangkok, hot, cool and rainy, from February 2018 until December 2018. Measurements were taken by the staff of the Toxicology group in the Chulabhorn Research Institute, Thailand and the Atmospheric Chemistry Research Group in the University of Bristol, UK, with the assistance of the PCD, Bangkok, at their sites.","keywords":"Thailand, PM10, composition, meteorology","publicationState":"published","dataPublishedTime":"2021-05-14T08:29:17","doiPublishedTime":null,"updateFrequency":"","status":"ongoing","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/32044/?format=json","dataPath":"/badc/deposited2020/thailand-particles/data/bristol-elpi/","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":84886,"numberOfFiles":3,"fileFormat":"Data are BADC-CSV formatted."},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/8787/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/2543/?format=json","nonGeographicFlag":false,"phenomena":["https://catalogue.ceda.ac.uk/api/v2/phenomona/67566/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67567/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67568/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67569/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67573/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67574/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67576/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67577/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67578/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67580/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67581/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67582/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67583/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67584/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67586/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67587/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67588/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67590/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67592/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67593/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67594/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67595/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/67596/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/101036/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/101037/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/101038/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/101039/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/101040/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/101041/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/101042/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/101043/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/101044/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/101045/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/101046/?format=json","https://catalogue.ceda.ac.uk/api/v2/phenomona/101047/?format=json"],"dataLineage":"Data sent by the project participants to the Centre for Environmental Data Anaylsis (CEDA) for archiving.","removedDataTime":null,"removedDataReason":"","language":"English","identifier_set":[],"projects":["https://catalogue.ceda.ac.uk/api/v2/projects/28097/?format=json"],"observationcollection_set":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/142015/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/142016/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/142017/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/142019/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/142020/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/142021/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/142018/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/142022/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/142023/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/168956/?format=json"],"procedureAcquisition":"https://catalogue.ceda.ac.uk/api/v2/acquisitions/32046/?format=json","procedureCompositeProcess":null,"procedureComputation":null,"permissions":[{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/2526/?format=json","useLimitation":null,"accessConstraints":null,"accessCategory":"public","accessRoles":null,"label":"public: None group","licenceURL":"http://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/","licenceClassifications":"any, attribution required"}],"discoveryKeywords":[{"ob_id":1138,"name":"NDGO0003"}]}
