“…On the Atlantic coast of northeastern Brazil, marine debris with different concentrations and sizes was observed, indicating recreational activities as the second predominant source of its generation (Cavalcante et al 2020). Wu et al (2021) observed that recreational beaches have more microplastic particles, evidencing that the level of contamination by microplastic particles in these recreational areas is directly related to tourist activities. Jeyasanta et al (2020) found a correlation between the concentrations of meso and microplastic and the degree of recreational activity.…”

“…The areas of use were considerably more contaminated than the adjacent areas that are not used for recreation, proving the anthropic effect in the contamination of microplastics in the bathhouses of the Central Amazon. As noted byWu et al (2021) at recreational beaches in Haichow Bay, China, where these activities were a potential factor in the release of microplastic particles.…”

“…In Brazil, recreational activities have been described as a contributing factor in the generation and the number of microplastic particles (Cavalcante et al 2020), as well as in other countries such as Singapore (Wu et al 2021). Thus, to provide information on microplastic contamination in freshwater environments, this study analyzed microplastic contamination in sediments from freshwater bathhouses used for recreation in the middle Amazon, Brazil.…”

The number of investigations has increased worldwide about the abundance and distribution of microplastics in different water bodies and biota. This study investigated microplastic contamination in bathhouses in the Middle Amazon, in Itacoatiara, AM, Brazil. A total of 202 microplastic particles were recorded in the five investigated areas used for recreation. These results indicate no significant difference in the number of microplastic particles between bathhouses (KW = 7.4805; P = 0.1126). The size of the microplastic particles differed significantly between the bathhouses (KW = 40.9582; P = 0.0001). Both blue and red microplastic particles were recorded, with blue particles being the most abundant. The microplastic particles were in the form of fibers and fragments. The number of microplastic particles (U = 7.4686; P = 0.0001) was significantly different between the areas within and adjacent to the bathhouses; however, the size of microplastic particles were not significantly different in the areas within and areas adjacent to the bathhouses (U = 0.6505; P = 0.5154). There was no significant correlation in the bathhouses between their frequency of use and contamination (number of microplastic particles) (rs = 0.4472; P = 0.4502). The results of this study indicate that microplastics are present in the bathhouses of the Middle Amazon and that contamination in areas used for recreation is significantly higher than in areas not used for this purpose.

“…However, the occurrence, distribution, and impacts of MPs had already been studied and detected in marine habitats from different parts of the world (Lo et al, 2018;Rodrigues et al, 2018;Anela et al, 2019;Botterell et al, 2019;Wieczorek et al, 2019;Li et al, 2020;Selvam et al, 2020;Wang Q. et al, 2020;Wong et al, 2020;Bhowmick et al, 2021;Gardon et al, 2021;Nithin et al, 2021;Sivagami et al, 2021;Taha et al, 2021;Wu et al, 2021;Yaranal et al, 2021). The presence of MPs was also documented in Bangladesh from sea salt (Parvin et al, 2022), fish species (Hossain et al, 2019(Hossain et al, , 2020Ghosh et al, 2021;Parvin et al, 2021), and the beach sediment of Cox's Bazar (Hossain et al, 2021).…”

Microplastics in Sediment of Kuakata Beach, Bangladesh: Occurrence, Spatial Distribution, and Risk Assessment

et al. 2022

Kuakata beach, known as Daughter of Sea in Bangladesh, has drawn a growing number of tourists from all over the world, leading to the higher use of single plastic products. This study was a first attempt to describe the occurrence, spatial distribution, and ecological risk of microplastics (MPs) in Kuakata beach sediments. A total of 24 surface sediment samples were collected from the intertidal zone of the beach, and MPs were extracted using the density separation method and a stereomicroscope. Fourier transform infrared (FTIR) spectroscopy was used for qualitative and quantitative identification. The results revealed that the average MPs in the beach sediment were 232 ± 52 items kg–1 dry weight, which was much higher than many other sandy beaches throughout the world. Analyses of variance showed a significant (p < 0.01) difference among the mean abundance of MPs in sampling points. Fibers were dominated in every sampling point with an average of 123 ± 27 item kg–1. Most of the MPs observed were colored (60%), and the rest were transparent (40%). It was found that the size range of 1–5 mm MPs constituted over half (55%) of total MPs covering an average value of 127 ± 34 items kg–1. Three polymer types were identified in the sediment samples through FTIR analysis which followed the decreasing order of polyethylene terephthalate > polyethylene > polypropylene. Correlation analysis showed a positive relationship between the abundance of MPs and the finer grain size of sediment (p = 0.055; r = 0.7), indicating grain size-controlled the density of MPs. The pollution load index was assessed to estimate the ecological risk and found that the beach sediment of Kuakata belonged to the risk category I of the pollution index. This investigation provided preliminary information on MPs pollution in the marine ecosystem that the policymakers can use to take appropriate management approaches.

“…The Shandong Peninsula is bound by Yellow and Bohai Sea. Numerious studies have been carried out to address microplastics issue in China (Xu et al 2020;Shen et al 2021;Wang et al 2021;Yuan et al 2021). Recently, we found few studies about the different aspects of microplastics which encompass the Yellow Sea (Sun et al 2018(Sun et al , 2019Xiong et al 2018;Zhou et al 2018;Zhang et al 2019;Zhao et al 2019;Gao et al 2020).…”

The current work provides the detailed analysis about microplastics contamination of the beach sediments and surface seawater. Sediment samples were collected from the high tidal zone at 13 beaches, and surface seawaters of seven stations along the southern Shandong Peninsula. The presence of microplastics was recorded on both beaches and surface seawater. The mean quantity of microplastics was approximately 664±80 microplastics/kg of dry weight (dw) with 0.5~0.125 mm in beach sediments, and 5.62±0.4 microplastics/liter (L) of surface seawater. Predominant microplastics were fibers (>97%). While other plastic forms had lower percentage. Microplastics possessed different color with polymer composition including polypropylene, polyethylene, and polystyrene. The accumulation of microplastics on beaches is an alarming issue and provides better understanding about microplastics pollution along the coastal regions of the southern Shandong Peninsula. It would also help to establish better monitoring system for future and evaluate possible risks by microplastics due to rapid economic growth of China.
