MICROPLASTIC POLLUTION IN THE DIPOLOG RIVER: ASSESSMENT AND IMPLICATIONS FOR SUSTAINABLE DEVELOPMENT

Abstract

Microplastic pollution is a critical environmental issue that affects aquatic ecosystems globally. This study investigates the presence, composition, and concentration of microplastics in the Dipolog River, a crucial water resource in Zamboanga del Norte, Philippines. The research utilizes a comprehensive sampling and analytical approach to assess the distribution of microplastics across three distinct sites: Piñan (upstream), Polanco (midstream), and Dipolog City (downstream). The findings reveal significant microplastic contamination, predominantly comprising fibers and fragments of polymers such as polyethylene (PE), polypropylene (PP), and polystyrene (PS). The study highlights the urgent need for sustainable waste management practices and public awareness to mitigate the adverse effects of microplastics on human health and the environment. The research also provides recommendations for policy development, infrastructure enhancement, and further research, contributing valuable baseline data for future studies.
