Nature Environment & Pollution Technology, 19(2).https://repoemc.ukm.my/handle/123456789/1531The occurrence of caffeine residue in Malaysian waters was successfully studied. The micropollutant abundance was recorded for three selected main rivers namely Terengganu, Ibai and Setiu which are located in Terengganu, Peninsular Malaysia. Surface water samples were taken twice in September and November 2018 from 15 sampling stations. Caffeine residue was determined using the solid phase extraction technique followed by a final analysis using a high performance liquid chromatography-UV detector.enEmerging contaminantStimulant drugRisk quotientPharmaceutical residueJournal
