Microplastic research in urban and industrial areas, including remote areas, have been conducted recently. However, there is still a lack of research about microplastic abundances in slum area. Ciwalengke River is located in Majalaya, Indonesia, which is dominated by slum and industrial areas that probably generate microplastics. This research was conducted to investigate the distribution of microplastic around the slum area for the first time. Surface water and sediment samples of the river were obtained at ten locations and grouped into six segments location based on different land use at the riverbank. Microplastic particles were identified using binocular microscope and categorized by shape and size. The average microplastic concentration were 5.85 ± 3.28 particles per liter of surface water and 3.03 ± 1.59 microplastic particles per 100 g of dry sediments. Microplastic concentration in the sediment samples were found to have significant differences in location segment (Kruskal Wallis test, p-value = 0.01165 < 0.05), but no significant differences were found in the water samples (Kruskal Wallis test; p-value = 0.654 > 0.05). In addition, microplastic distribution was dominated by fiber particle. More fiber shape might be derived from the direct clothing of residents in the river and fabric washing process in the textile industries. This was also revealed by Raman spectroscopy test of several microplastic particles indicating that the type of microplastic were polyester and nylon.
This paper characterizes the fungal and bacterial colonizers of 5 types of plastic films (High-Density Polyethylene, Low-Density Polyethylene, Polypropylene, Polystyrene, and Polyethylene Terephthalate) throughout a 242-day incubation in the south-eastern Mediterranean and relates them to the chemical changes observed on the surface of the samples via ATR-FTIR. Neither bacterial nor fungal community structures were related[…]
This paper provides insights into the sustainable alternatives that can replace conventional plastic mulches, such as biodegradable mulches made from natural fibers and biopolymers. The microscopic and FTIR analyses conducted during the study showed the degradation of the fibers from the mulches during the exposure time to a certain extent. The nonwoven mulches provide higher[…]
This paper investigates the degradation of biodegradable polybutylene adipate terephthalate/polylactic acid (PBAT/PLA) and traditional polyethylene (PE) plastic under two typical abiotic conditions: ultraviolet (UV) irradiation and mechanical abrasion (MA) for up to nine months. The quantitative analysis of the degradation products was carried out using membrane filtration and total organic carbon determination (MF-TOCD). The results[…]
This paper identifies technological innovation, policy formulation, advocacy and sensitization, and bioremediation as some of the approaches that are currently used for the mitigation of plastic pollution in Nigeria. This chapter also highlights the need to encourage, enhance, and disseminate scientific research on mitigating the harmful effects of plastic pollution in Nigeria. It concluded with[…]
This review provides insights into the sources of microplastics, the ecotoxicity of microplastics, and the impact microplastics have on aquatic and marine life, management, and bioremediation of microplastics. Policies and strategies adopted by the government to combat microplastic pollution are also discussed in this review. Microplastics tend to accumulate in many aquatic systems, contaminate them,[…]
