“…Due to the transport and deposition of MaP in the floodplain area, it can be overlaid by further sedimentation events and thus found in deeper layers. Sampling at the banks of five different rivers in Nigeria has shown high levels of MaP contamination, with 3487 waste items/m 2 (>5 cm), 59% of which were MaP [133]. Along the Paranà River in Argentina, the average MaP abundance was 5.05 items/m 2 [134].…”

With the focus on microplastic in current research, macroplastic is often not further considered. Thus, this review paper is the first to analyse the entry paths, accumulation zones, and sinks of macroplastic in the aquatic, terrestrial, and atmospheric environment by presenting transport paths and concentrations in the environment as well as related risks. This is done by applying the Source–Pathway–Receptor model on macroplastic in the environment. Based on this model, the life cycle of macroplastic is structurally described, and knowledge gaps are identified. Hence, current research aspects on macroplastic as well as a sound delimitation between macro- and microplastic that can be applied to future research are indicated. The results can be used as basic information for further research and show a qualitative assessment of the impact of macroplastic that ends up in the environment and accumulates there. Furthermore, the applied model allows for the first time a quantitative and structured approach to macroplastic in the environment.

“…Metode yang digunakan adalah gabungan tempat (integrated samples). Pengambilan sampel dilakukan pada pinggiran kiri, tengah dan pinggiran kanan sungai (Ebere et al, 2019). Pengambilan sampel air dilakukan pada kedalaman setengah kedalaman total sungai (½h) dan kedalaman sedimen 0-10cm dari permukaan atas sedimen.…”

“…Bentuk fragment memiliki karakteristik fisik yaitu bentuk yang tidak beraturan, tebal dengan tepi yang tajam. (Ebere et al, 2019) Penelitian menunjukkan bahwa asal dan jalur masuknya mikroplastik menentukan bentuk dari mikroplastik tersebut (Pan et al, 2019). Pencemaran mikroplastik dari sumber antropogenik seperti limbah rumah tangga menyumbang mikroplastik berbentuk fragment terbesar.…”

Sungai adalah salah satu jalur masuknya plastik ke lautan. Plastik bersifat presisten dan tahan lama tetapi paparan radiasi ultraviolet serta abrasi fisik mampu memecah plastik menjadi puing-puing kecil berukuran mikro sampai dengan nano yang disebut mikroplastik. Penelitian ini bertujuan untuk menganalisa jenis, bentuk dan jumlah mikroplastik di air dan sedimen Sungai Sei Sikambing Medan. Metode penelitian dilakukan dengan pengambilan sampel air dan sedimen sungai berdasarkan SNI 03-7016-2004 dan sampel merupakan hasil dari gabungan tempat (integrated samples). Pemisahan mikroplastik dilakukan dengan penyaringan, pengancuran senyawa organik, pemisahan berdasarkan berat jenis dan penyaringan menggunakan vacuum. Identifikasi jenis dan bentuk mikroplastik dilakukan dengan menggunakan FTIR dan menganalisa kelimpahan mikroplastik dilakukan dengan menggunakan mikroskop. Hasil penelitian menunjukkan Sungai Sei Sikambing mengandung mikroplastik jenis polietilen, polipropilen dan polisterin dengan bentuk film, fragment, granule, foam dan fiber. Jumlah rata-rata mikroplastik di air Sungai Sei Sikambing adalah 28,6 partikel/250 ml air sungai dan 32,3 partikel/100 g berat kering sedimen Sungai Sei Sikambing.

“…Plastic and solid wastes are dumped at illegal dumpsites, by the roadside or inside drainage channels (Adegboye 2018;Imam et al 2008) clogging gutters and littering streets following rainfalls, and swept into the marine ecosystems by floodwater (Dumbili & Henderson 2020). Microplastics, tiny particles under 5 mm in length (SAPEA, 2019) have been identified in rivers located in Eastern Nigeria (Ebere et al 2019) and Western Nigeria (Akindele, Ehlers & Koop 2019).…”

Nigeria is reported as having released up to 0.34 million tonnes of plastic debris into the ocean in 2010 and ranked ninth country in the world for pollution of the marine environment. It is a postcolonial, oil-rich country where plastic is cheap and widely available. Currently, there is no government policy regulating single-use plastic products. Previous studies have identified university student residential areas as ‘hot spots’ for plastic waste. We used qualitative methods (focus groups and semi-structured interviews) to explore how students made sense of their single use plastics consumption (including ‘pure water’ plastic sachets) and analysed how young Nigerians interact with plastic waste. Students perceived plastic waste as malodorous, causing harm to human health and blighting environmental aesthetics. Students saw themselves as the cause of plastic pollution (as consumers) whereas plastic industries were framed positively as producers bringing progress and prosperity. Participants were open about their indiscriminate littering practices subverting other study findings where responsibility tends to be deflected (to policy makers, producers). While we are relying on self-reported behaviour, we found no obvious link between awareness of environmental harm caused by plastic pollution and students’ actions. Within this peer group of young Nigerians, it was not considered ‘normal’ or ‘cool’ socially to use waste bins or recycle. We suggest that further research is needed into how plastic pollution is made sense of in terms of individual responsibility; lay understandings of miasmas; perceptions of public/private spaces and plastics as a signifier of modernity and enhanced social status.
