ASEANO Primer: Survey on Plastic Litter Along Imus River

This study assesses the extent of plastic pollution in the Imus River by quantifying and characterizing macroplastics and microplastics. The water quality of the river was also assessed based on its physicochemical characteristics to confirm the Class-C (intended for fisheries, agriculture, and recreational use) classification of the river per DENR standards. Physicochemical parameters were correlated to the quantities of collected plastic litter.
