Spatial analysis and source profiling of beta-agonists and sulfonamides in Langat River basin, Malaysia. Science of the total environment, 548, 43-50.https://repoemc.ukm.my/handle/123456789/1568Beta-agonists and sulfonamides are widely used for treating both humans and livestock for bronchial and cardiac problems, infectious disease and even as growth promoters. There are concerns about their potential environmental impacts, such as producing drug resistance in bacteria. This study focused on their spatial distribution in surface water and the identification of pollution sources in the Langat River basin, which is one of the most urbanized watersheds in Malaysia.enBeta-agonistsSulfonamidesLangat River basinSpatial analysisSource profilingJournal
