“…In this case, samples are drawn into glass or metal bottles. In bulk sampling, it is also possible to use suction pumps or sample bottles, such as a Niskin bottle [ 70 , 71 ]. The volume-reduced sampling procedure is commonly used to collect particles from large water volumes [ 72 ].…”

Plastic particles smaller than 5 mm, i.e., microplastics, have been detected in a number of environments. The number of studies on microplastics in marine environments, fresh water, wastewater, the atmosphere, and the human body are increasing along with a rise in the amounts of plastic materials introduced into the environment every year, all contributing to a range of health and environmental issues. Although the use of primary microplastics has been gradually reduced by recent legislation in many countries, new knowledge and data on these problems are needed to understand the overall lifecycle of secondary microplastics in particular. The aim of this review is to provide unified information on the pathways of microplastics into the environment, their degradation, and related legislation, with a special focus on the methods of their sampling, determination, and instrumental analysis. To deal with the health and environmental issues associated with the abundance of microplastics in the environment, researchers should focus on agreeing on a uniform methodology to determine the gravity of the problem through obtaining comparable data, thus leading to new and stricter legislation enforcing more sustainable plastic production and recycling, and hopefully contributing to reversing the trend of high amounts of microplastics worldwide.

“…Water, its bottling, and its branding have thus become a mode of enclosure writ small, embedded in discourses of paradise and good health that depend upon the exclusion of local populations. Meanwhile, the ecotone is overtaken by pollution from effluent, garbage, and chemicals that run into seawater that is already teeming with microplastics (Dehm et al 2020).…”

This editorial introduces the special issue, ‘World Literature and the Blue Humanities’. The authors articulate the commonalities and tensions between world literature, world-ecology, blue humanities, and hydrocultural approaches. Taking megadams, water pollution, and the blue revolution as baselines, we offer short analyses of works by Namwali Serpell, Craig Santos Perez, Jean Arasanayagam, Paul Greengrass, Will Menmuir, and Emily St. John Mandel in order to articulate how culture can both contest and normalize water enclosure. The piece ends with a brief summary of the contributions to the special issue.

“…Specifically, the major route of human exposure to MPs is ingestion, which can lead to inflammatory lesions and immune disorders [16][17][18] . In Fiji, recent screenings have found MPs in seawater, sediments, and marine fishes [19][20][21] , while PAHs have not been studied yet 22 . However, studies elsewhere have found PAHs in different marine compartments like sediments, water and biota [23][24][25] .…”

“…Vueti Navakavu LMMA was designated in 2002 after the villagers identified several threats affecting the area, among which chemical and solid waste pollution were mentioned 65 . Despite the conservation effort, MPs pollution has been found in the locally managed marine area 19,20 . In addition, ocean surface currents, influenced by the southeast tradewinds 66 , might have brought in pollutants from the closeby Suva Harbour, where the presence of MPs and heavy metals, for example, has already been reported 19,20,67,68 .…”

To determine the baseline threat of microplastics and polycyclic aromatic hydrocarbons (PAHs) in an important seafood fish from Vueti Navakavu LMMA, a multibiomarker risk assessment was conducted on the thumbprint emperor fish. K-factor was significantly lower in samples from the wet season compared to the dry season but no significant differences were observed for HSI between seasonal groups. PAHs levels of four metabolites in emperor fish from Fiji waters is reported here for the first time; seasonal groups showed no significant differences, but all samples presented levels of biliary PAHs. The specimens also contained at least one microplastic in its gastrointestinal system; fibres were the predominant form-type and ingestion levels showed that more than 80 % of fragment sizes were below 1.0 mm. Biochemical responses were observed for EROD and GST biotransformation activity, oxidative stress (GPX and GR activity; LPO concentration) and genotoxicity (micronuclei assay). Though there were no statistically significant differences found, there were biological significances that were important to note; relatively low levels of pollutant exposure showed low levels of biochemical responses as well, and enzymes response were as expected to their roles in the body. This reflects that a multibiomarker approach can be helpful to monitor future trends of pollution levels, and help improve or strengthen the efforts of existing conservation mechanisms such as LMMAs. Coastal communities consume 0.55 kgs more seafood fishes annually in the world, so their livelihood security and health safety should be paramount in our efforts to curb the issue. We recommend adopting new techniques, like biomonitoring, to improve the conservation mechanisms and systems in place.
