Summary

Researchers investigated how urbanisation on small islands in Indonesia affects microplastic contamination levels in benthic organisms and sediments, examining the impact of land use conversions from pristine ecosystems to settlements and tourism facilities.

Study Type Environmental

Indonesia is an archipelago country comprising thousands of islands, including small islands. Currently, small islands have experienced urbanization in the forms of land use developments and conversions from pristine ecosystems to settlements and tourism facilities, leading to the contamination of microplastics. Despite growing numbers of research on microplastic in water, there is still limited information about microplastic in the sediment and benthic, in particular in developed small island environments. This study compared the types of land use on the island from reserved areas, tourism, and settlement. The microplastics were characterized based on the shapes. The results confirm that land use types and development can impact the microplastics in sediment and benthic organisms. The orders of microplastic contents regarding the land use types were settlement > tourism > reserved areas. The orders of microplastic contents in sediment and benthic organisms regarding the shapes were fiber > fragment > film. The impacts of microplastics were measured using the Coefficient of Microplastic Impact (CMPI). According to the CMPI, settlement has been extremely impacted due to fibers. The result of this study encourages related stakeholders to immediately take precautions regarding the rapid development and conversion of land use in the pristine ecosystem of a small island.

Presence of microplastics in water, sediments and fish species in an urban coastal environment of Fiji, a Pacific small island developing state

Researchers conducted the first assessment of microplastic levels in surface water, sediments, and fish from the urban coastal environment of Suva, Fiji. The study confirmed the presence of microplastics across all three matrices in this Pacific small island developing state, and evaluated contributions from local sources including wastewater, highlighting that microplastic pollution affects even remote island nations.

Distribution of Microplastics in Coastal Waters and Their Implications for the Marine Food Chain

Researchers sampled surface water, sediments, and marine organisms from urban, industrial, and conservation coastal zones in Indonesia to assess microplastic distribution and food chain implications. Industrial zones had the highest microplastic concentrations, and filter feeders accumulated more particles than fin fish, indicating distinct exposure pathways through the marine food web.

Abundance and characterization of microplastic pollution in the wildlife reserve, Ramsar site, recreational areas, and national park in northern Jakarta and Kepulauan Seribu, Indonesia

This is the first study to measure microplastic pollution in sediments across protected areas near Jakarta, Indonesia, including a wildlife reserve, a Ramsar wetland site, and a marine national park. Microplastics were found at all locations, with higher concentrations closer to human activity and during the dry season. The results suggest that even designated conservation areas are not spared from microplastic contamination.

Microplastic in tropical island estuaries in China: Source identification and management framework development

Researchers found surprisingly higher microplastic concentrations in the less-urbanized Wanquan River Estuary compared to the Nandu River Estuary in Hainan Island, China, suggesting that tourism and agricultural activities may contribute more significantly to microplastic pollution than urbanization alone.
