“…The most abundant MP form was fragment in this study, accounting for 60 % (average value 109.44 items per kg) of total MPs. Similar results were reported by Bayo et al 12 in a lagoon environment in Spain. The concentrations of other microplastics in the order of their abundance are films (30.45 items per kg, 17 %), fibers (23.12 items per kg, 12 %), and spheres (19.53 items per kg, 11 %).…”

“…The most abundant MP form was fragment in this study, accounting for 60 % (average value 109.44 items per kg) of total MPs. Similar results were reported by Bayo et al [12] In all zones, the PE fiber type and fragment morphology type were dominant. The zone-wise abundance of MPs was different for monsoon months (Zone I > Zone II > Zone III) and nonmonsoon months (Zone I > Zone III > Zone II).…”

was carried out in the beach sediments of Calicut to understand the monthly accumulation and deposition pattern of microplastics (MP). The average abundance in terms of items per kg dry sediment during monsoon months was higher than that of non-monsoon months. The sources and pathways of the sampled microplastics were identified using an existing forensic framework. The pathways of pellets and fibers were seen as drainage outlet and harbor, respectively. Exactly identified sources include polycarbonate urethane (PCU) fragments from foam, polypropylene (PP) and polyethylene (PE)+PP films from paints of boats, and PE and PE+PP from fishing nets. The MP concentration in recreational areas was consistently higher except during flood periods.

Fourier transform infrared (FTIR) spectroscopy has been extensively used in microplastic (MP) pollution research since 2004. The aim of this review is to discuss and highlight the recent advances in FTIR (spectroscopy and chemical imaging) techniques that are used to characterize various polymer types of MPs and to trace their fate and transport in different environmental matrices. More than 400 research papers dealing with FTIR techniques in MP pollution research, which are published between January 2010 and December 2019, have been identified from the Scopus and Web of Science databases. The MPs present in sediment, water (marine and freshwater), biota, air/dust, waste water treatment plants and salt are further classified according to (1) characterization and identification, (2) weathering and aging, (3) ecotoxicology, and (4) analytical methods. The results revealed that the ATR-FTIR technique is mostly used to identify and characterize the MPs found in water and sediment. The mFTIR (FTIR imaging) is extensively used to study the ingestion of MPs in biota (both marine and freshwater). In this article, we have summarized the current knowledge of application of FTIR spectroscopy to MP research and provided insights to future challenges for understanding the risk of MPs.

“…Analysis of variance confirmed that the removal of LDPE from INF (1.69 ± 0.59 items l -1 ) to RSF (0.06 ± 0.04 items l -1 ) was statistically significant (F-test = 7.634, p = 0.001). Other polymer types, as EPM and PV, previously reported in relatively high number in beach sediments [33] because their use in packaging and shipbuilding, respectively, only represented 1.07% and 0.50% in wastewater samples.…”

This paper discusses the role of two different wastewater treatment technologies in the removal efficiency of microplastics from the final effluent of an urban wastewater treatment plant; i.e., a membrane bioreactor as an advanced wastewater treatment technology and rapid sand filtration as a tertiary treatment after an activated sludge process. Fourteen different polymer types were identified in all wastewater samples, mainly represented by low-density polyethylene (71.89%), high-density polyethylene (5.44%), acrylate (5.24%), polypropylene (5.22%), polystyrene (4.24%), and nylon (2.56%). The main forms isolated were fibres (61.2%), followed by films (31.5%), fragments (6.7%), and beads (0.6%). The main size interval corresponded to 1 and 2 mm, accounting for 28.2%, 37.3%, and 36.8% for the influent, membrane bioreactor, and rapid sand filtration, respectively. A total of 480 microplastic particles were isolated in all wastewater samples, with an average concentration of 2.16 ± 0.42 items l-1 , and removal rate percentages of 79.01% for the membrane bioreactor and 75.49% for rapid sand filtration. Both technologies proved to be more efficient removing particulate microplastics (98.83% and 95.53%, respectively) than fibres (57.61% and 53.83%, respectively), showing a clear escape into the aquatic environment for fibres. The average microplastic size displayed a statistically significant increase from the influent of the sewage treatment plant (1.05 ± 0.05 mm), to rapid sand filtration effluent (1.15 ± 0.08 mm) and membrane bioreactor (1.39 ± 0.15 mm) (F-test = 4.014, p = 0.019) indicating the fibre selection made by advanced treatment technologies previously discussed.
