Microplastic Contamination in Seafood: Knowledge and Awareness of Fishermen and Consumers in Negombo Lagoon Area
Summary
This study assessed the level of awareness among fishermen and consumers in Negombo, Sri Lanka about microplastic contamination in seafood, identifying knowledge gaps that could affect food safety behavior. The survey found limited understanding of microplastic risks among both fishing communities and the general public.
Microplastics (MP) are tiny plastic particles (<5 mm) which are widespread in freshwater, marine, and terrestrial ecosystems. MP become significant environmental threat and there is a possibility to end up MP in seafoods. The present study assessed the level of awareness regarding contamination of seafood with MP among consumers and fishermen in Negombo lagoon area. Data were collected from 60 participants (30 fishermen and 30 consumers) via administered questionnaire with closed- ended and open-ended questions which extract the information on awareness about MP. Findings revealed that awareness on MP were relatively low in Fishermen (36.67%) but higher in consumers (63.33%). Further 40% of fishermen and 60% of consumers had knowledge on impact of MPs on human health. However, some fishermen (56.67%) and consumers (43.33%) had no knowledge about the sources of MP. Majority of respondents had given X-press pearl (47.06%) and hotel wastage (29.41%) as the main sources of MP. Moreover, 45% of fishermen had observed plastics attached in gills and gut of fish. Respondents were generally aware that there is a risk of bioaccumulating MP after consuming seafood and apprehension regarding potential hazard to human health. Durability was the main reason for the selection of plastics used by respondents while recyclability played a lesser role. Only 36% of fishermen and 64% of consumers were found to be aware of the methods for reducing MP pollution. Both consumers and fishermen have acknowledged the importance of awareness programs on plastic pollution and its harmful effects, as well as the importance of reducing and recycling plastics in mitigating the issue. Majority of consumers (75%) and a smaller number of fishermen (25%) have actively engaged in environmental initiatives, such as beach clean-ups. All participants display a strong willingness to adopt biodegradable alternatives, emphasizing their commitment to eco-friendly practices. Educational campaigns and media awareness, coupled with stringent policy enforcement and eco- friendly plastic adoption, can mitigate plastic and microplastic pollution, addressing the ongoing issue effectively.

Community awareness and perceptions on microplastics: a case study from Sri Lanka
A community survey in Sri Lanka assessed public awareness of microplastic pollution using convenience sampling across rural and urban areas, finding generally low awareness of microplastics as an environmental and health concern. The results highlight the need for public education campaigns about microplastic risks and regulatory measures.
Microplastic Contamination in Shrimps from the Negombo Lagoon—Sri Lanka
Researchers analyzed microplastic contamination in two species of shrimp from Sri Lanka's Negombo Lagoon, examining both gastrointestinal tracts and gills. The study found microplastics present in all sampled shrimp, raising concerns about human dietary exposure to microplastics through seafood consumption in coastal communities.
Microplastics Trophic Transfer in Seafood Varieties Caught from the Coastal Waters off Negombo
This study examined microplastic trophic transfer among five commercially important seafood species caught from coastal waters off Negombo, Sri Lanka, analyzing tissues to trace how plastics move through the food web. Results showed microplastics were present across trophic levels, with contamination patterns differing by species and tissue type.
Microplastic presence in dried and fresh fish from seafood markets in Sri Lanka
Scientists examined both fresh and dried fish from seafood markets across Sri Lanka and found microplastics in over 82% of the samples, with fiber-shaped pieces making up more than 95% of the contamination. Fresh fish had higher contamination levels than dried fish, suggesting that preparation methods affect microplastic content. Since these small fish species are commonly eaten whole, consumers may be ingesting significant amounts of microplastics through popular seafood products.
