Surabaya River is one of the lower tributary of the Brantas, which is included as the top 20 plastic polluted rivers worldwide. The main function of Surabaya River is for raw water source for Surabaya City. Besides, this river is used for domestic and industrial waste discharges, and for irrigation. This study aimed to investigate the distribution of microplastics (MPs/MP) and its characteristics in three stratified depths (surface, middle, and bottom) of the river. This study was conducted in eight sampling sites, which were located in the Lower Brantas and the Surabaya Rivers. The MP abundance in the surface, middle, and bottom of the river ranged 1.47–43.11; 0.76–12.56; and 1.43–34.63 particles/m3, respectively. The highest average of MP abundance was 21.16 particles/m3 at the lower end of the river. The MP particles tend to be mainly distributed in the surface than in the other depth levels. The MP particles in each depth were generally dominated by film shaped large MP of 1–5 mm size, and transparent in color. Three main polymer types of the MPs were low density polyethylene, polypropylene, and polyethylene.
The paper studies the microplastic abundances and characteristics in the Southern Jiangsu Canal to reveal the effect of riverside cities on microplastics in river water. The results show that the microplastic abundance in the water body of the South Jiangsu Canal ranges from 3.41 to 19.07 particles L−1, with an average of 9.59 ± 3.95[…]
This paper reveals the status of microplastic pollution in paddy soil with long-term mulching. The study investigates the distribution and weathering characteristics of filmy microplastics in a mulched paddy field (non-mulched, four years of mulched, and ten years of continuous mulched soil were investigated) in Southwest China. The filmy microplastics accumulated annually in the plough[…]
The paper reviews advancements in polymer technologies that aim to improve the efficiency of recycling and upcycling plastic waste. Increasing the rate of recycling and upcycling is critical for addressing the issues caused by plastic pollution, and, at the same time, overcoming the technical limitations on the same. The research emphasises the need to develop[…]
The study analyses the current advancements in the behavioural differences between MPs and NPs in urban waters. Analytical challenges, fate, interactions with surrounding pollutants, and eco-impacts of MPs and NPs are similarly discussed in this paper. It has been highlighted in the study that the characterization and fate studies of NPs are more challenging as[…]
The study investigates scientifically evidence-based policy initiatives for targeting plastic pollution. The issue of plastic pollution is complex and still related to several uncertainties, which implies that policy initiatives must allow for flexibility and ongoing evaluations to adjust to the evolving knowledge generation. It is also important that the scientific community provide the needed research[…]
