The studies regarding the occurrence of microplastics in marine environments are very limited, hence its actual impact on human health, the marine ecosystem, and biota is yet to be fully determined. This study investigates the presence and characteristics of microplastics in Asian Green Mussels (Perna viridis) in the coastal waters of Navotas City, Philippines. Accordingly, the study intends to assess the water quality in the area, characterize the Asian Green Mussels, and analyze the possible sources linked with each type of polymer recovered from the sampling locations. The coastal waters were assessed through an in-situ approach using a multi-tester whereas findings revealed that the physicochemical parameters of water at all sampling sites were within acceptable limits for Class SB water bodies standards provided by the Department of Environment and Natural Resources (DENR). The microplastics within the sample mussels were isolated through the use of three parts analytical-grade KOH and one part 10% H2O2, the improvised protocol was based on several research suggestions, and it yielded positive results in the current study, as microplastics were successfully detected through the use an ATR-FTIR Spectrophotometer. The majority of microplastics identified were less than 1 millimeter in size, predominantly fibrous and fragmented in shape, with polymers such as polypropylene (PP), polyethylene (PE), and polyamide (PA) being most common. Findings suggest that the detected microplastics in the study can be attributed to the high urbanization of Navotas City according to its land use map. The findings further signify the existence of microplastics in marine organisms, particularly in such species viable for human consumption, hence, this study emphasizes the need for improved environmental policies and practices to mitigate this pollution and its potential impact on human health and marine life.
