Microplastics in subsurface coastal waters along the southern coast of Viti Levu in Fiji, South Pacific

Marine Pollution Bulletin 2020 46 citations

AI summary Read the abstract

Microplastics were found in subsurface coastal waters at both urban and rural sites along Fiji's main island, with no significant difference between settings. Even rural and less-developed coastal areas in small island nations experience widespread microplastic contamination.

Microplastics (MPs) remain largely understudied in Small Island Developing States. This study is aimed at comparing the abundance and characteristics of MPs in rural and urban marine coastal sites located along the southern coast of Fiji's main inhabited island, Viti Levu. Collection of subsurface waters (at depth of ca. 0.6 m) was performed at seven sites via Niskin bottle. Samples were filtered over a membrane filter to extract MPs and to allow visual analysis and polymer identification by using attenuated total reflectance in Fourier transform infrared spectroscopy. Findings from this study depict widespread presence of MPs in both urban and rural sites, and show no significant differences in the four parameters studied, i.e. abundance of MP pieces (2.0 vs 1.6 MP/L, respectively), form types (dominance of fibers), size (0.5-0.9 and 1.0-1.4 mm totaling 48% of the samples), and color (blue contributing 30%, and red and black contributing 25% each). These findings challenge the common expectation of a higher MPs pollution in urban areas compared to rural areas.

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

AI summary Read the abstract

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.

Researchers surveyed microplastic contamination along the coastline of West Iceland, finding plastic particles at urban and some semi-rural sites near Reykjavik but none at rural locations, though the distribution was uneven due to strong ocean currents rather than a simple gradient of decreasing pollution away from the city.

Researchers tested stormwater and runoff water near industrial sites on Fiji's main island for microplastics, finding an average of 2.23 particles per liter. Most particles were small plastic fragments and fibers, mainly polyethylene and polystyrene, materials commonly used in packaging.

Spatial distribution of microplastics around an inhabited coral island in the Maldives, Indian Ocean

AI summary Read the abstract

Researchers investigated microplastic accumulation across fore reef, reef flat, and beach sediment environments surrounding a small inhabited coral island in the Maldives, finding 1,244 individual microplastic pieces across 22 sampling sites. The study reveals that even remote inhabited islands in the Indian Ocean show significant microplastic contamination, with spatial distribution patterns reflecting local hydrodynamics and human activities.

Evidence of elevated microplastic accumulation in Pacific Island mangrove sediments

AI summary Read the abstract

Researchers found that mangrove sediments in Fiji contained nearly ten times more microplastics than surrounding non-mangrove areas, with consistent results across both urban and rural sites. Fibers were the most common type of microplastic found, and the contamination levels were comparable to heavily polluted regions elsewhere in the world. The study highlights that mangroves, while vital coastal ecosystems, may be acting as significant traps for microplastic pollution in Pacific Island nations.
