Despite Indonesia being considered as second highest source of marine plastic debris in the world, few studies have been conducted on plastic debris in Indonesia, particularly microplastics. By using a simple device to simultaneously grade floating microplastics, we investigated microplastic contamination in the ecosystem of small islands in Bintan Regency, Riau Island Province, Indonesia. The average number of floating microplastics from 11 beach stations around Bintan Island was 122.8 ± 67.8 pieces per station, which corresponds to 0.45 pieces per m3 and represents a low-medium microplastic pollution level compared to the levels of other marine environments worldwide. Polymer identification using Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) Spectroscopy successfully identified Polyethylene (PE) (17.3 ± 8.3%), Low Density PE (17.6 ± 5.5%), Oxidized LDPE (<0.1%), Polypropylene (PP) (54 ± 13%), PP Atactic (<0.4%), PP isotactic (<0.2%) and Polystyrene (PS) (10.4 ± 9.1%) from different forms and shapes of microplastics i.e., fragments (50.9 ± 4.9%), fibers (26.2 ± 3%), granule (13.1 ± 3.8%) and films (9.8 ± 5.1%). We suggest that the generation of these microplastics was likely due to physicochemical processes, including biological degradation in this tropical ecosystem. Environmental implication of microplastics in this area increases the problems associated with ingestion, bioaccumulation and biomagnification across trophic levels and co-pollutants absorbed onto microplastics.
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[…]
