“…The lower ability of fish DI cells to phagocytose MPs could be a beneficial adaptation to prevent or reduce the uptake of particles from the food. Several fish species ingest and accumulate MPs in the digestive tract (Bråte et al, 2017) as well as in several other tissues, such as the gills, liver and even in the brain (Ding et al, 2018). It has been suggested that MPs translocate from the gut into the circulatory system in fish, which in turn will transport them to other tissues and organs (Ding et al, 2018;Wang et al, 2020).…”

“…We found that PE-MP accumulates more easily than PS-MP in the immune cells of the Atlantic salmon. PE is the most abundant MP polymer in the marine environment (Enders et al, 2015;Ter Halle et al, 2017;Erni-Cassola et al, 2019;Pannetier et al, 2020) and, therefore, the most often ingested polymer by fishes (Rummel et al, 2016;Bråte et al, 2017). Hence, the impact of PE-MPs on wild populations of salmonid species cannot be ignored.…”

“…The type of polymers ingested by an organism depends on its ecological niche. Pelagic fish tend to ingest lowdensity polymers since they normally float in seawater, while demersal fish preferably ingest polymers with higher densities than seawater as such particles sink and are mainly present in deep waters (Bråte et al, 2017). A few studies have reported that different MP polymers induce different toxicities in fish.…”

The ubiquitous presence of microplastics and their marine ecotoxicity are major public concerns. Microplastics are ingested accidentally by the marine fauna or are taken up indirectly through the food chain. These particles can accumulate in cells and tissues and affect the normal biological functions of organisms, including their defense mechanisms. There is limited information available about the response of immune cells to microplastics; the degree of uptake by the cells, the response of different organs or the impact of environmental concentrations of microplastic are matters that remain unclear. Moreover, very little is known about the toxicity of different polymer types. This study aimed to shed light on the physical impact of small microplastics (1–5 μm) on cells from Atlantic salmon. Immune cells from intestine, blood, and head kidney were exposed to green fluorescent polyethylene microplastic (PE-MP), yellow fluorescent polystyrene microplastic (PS-MP) and both. High (50 mg/L), medium (5 mg/L), and low (0.05 mg/L) concentrations were tested for 1, 24, 48, and 72 h to study cell mortality and microplastic uptake. Quantitative data of microplastic uptake by fish immune cells were obtained for the first time by imaging flow cytometry. Salmon immune cells showed a relatively low ability to phagocytose microplastics. Less than 6% of the cells ingested the particles after 48 h of exposure to high concentrations. Cells also phagocytosed microplastics at low concentrations although at low rates (<0.1%). PE-MPs was phagocytosed by higher percentage of cells compared to PS-MPs and the former bioaccumulated in time while the latter decreased over time. However, each cell generally phagocytosed more PS-MPs particles than PE-MPs. Cells from different tissues showed different responses to the microplastic polymers. In conclusion, this study shows that immune cells of Atlantic salmon can phagocytose microplastics, and the impact is dependent on the microplastic type. PE-MPs, the most abundant polymer in the oceans and a widely used plastic in salmon aquaculture, was more easily taken up than PS-MPs. Furthermore, the study demonstrates how imaging flow cytometry can be applied in microplastics research.

“…Research has revealed how materials travel and circulate with dominating ocean currents, how particles even freeze into and travel with drift ice to eventually be released from it again, and how this is affecting fauna and flora (e.g. Lusher et al 2015;Bergmann et al 2017;Bråte et al 2017;Halsband et al 2018). Importantly, however, drift matter is far from being a new phenomenon on these northern shores (anymore than it is in other parts of the world).…”

Anticipated futures? Knowing the heritage of drift matter

What might heritage in and of the Anthropocene look like? This article ponders this question by drawing on archaeological encounters with assemblages of drift matter (seaborne debris) in Norway and Iceland. Here, drift matter manifests evidence of both the relentlessly amassing material heritage of the Anthropocene and deep legacies of local engagement with this fluctuating resource. The tensions evoked along these coastlines therefore invite explorations of some of the challenges met in the current climate, problematizing conceptions of heritage and waste, wanteds and unwanteds, salvation and loss. Surely, drift matter is today largely perceived as not belonging in these natural environs. However, are there other thing lessons to be learned from taking seriously this heritage? Avoiding an interpretation of these things as out of context and a focus merely on what has been lost, this article asks whether it is possible that the sense of ambiguity, flux and drift emitted by this material may not only challenge but also enable alternative possibilities of knowing thingsalternatives that may be of significance for a heritage in and of the Anthropocene.

“…Pencemaran plastik saat ini merupakan problem utama (main problem) yang diterima oleh lingkungan, terutama perairan. Berdasarkan data yang dihimpun dari penelitian Brate et al (2017) Produksi global plastik mencapai 322 juta ton pada tahun 2015 yang pada akhirnya menghasilkan produk limbah ketika barang mencapai akhir penggunaannya. Plastik akan terlarut di perairan dan akan membentuk ukuranukuran kecil (micro-plastik) berdampak pada biota.…”

Abstrac :Plastic pollution / waste has an impact that will disturb the stability of the ecosystem, especially aquatic organisms such as fish. The main source of plastic contamination comes from household waste that is not managed properly, especially in coastal areas that make the sea as a place of final discharge. Plastic pollution is currently the main problem that is accepted by the environment, especially water. Plastic will dissolve in the waters and will form small sizes (micro-plastic) impacting biota, including fish. Fish including aquatic organisms that can not distinguish between food and plastic particles clearly, thus providing an effect on digestion and growth. The results showed the growth rate of silver Pompanoo with the highest plastic concentration will cause slower growth, the control treatment is the best growth yield compared to treatments that have a plastic content mixed with feed. Growth of weights with the highest concentration of plastic particles is 0,48 gr/week, length growth is 0.75 cm / week, and survival is 69.17% and shows the growth and survival rates are worse or there is a tendency to worsen with an increase in the concentration of plastic contamination . Plastic particles consumed by fish are not digested properly and can even cause the growth response of fish to be slow even to death.
