“…The Karnaphuli river flows from the Lushai hills in Mizoram, India, and has a watershed area of nearly 11,000 km 2 2 , 31 ; and travels 180 km of Rangamati mountainous wilderness, Bangladesh. Further, the Karnaphuli River estuary flows about 170 km via the port city of Chittagong and ends in the Bay of Bengal 32 . The estuary is abundant with semidiurnal tides of 2–4 m range with a mean depth of 8–10 m in the external zone of the river 33 .…”

Microplastics (MPs) have become an emerging global pollutant due to their widespread dispersion and potential threats to marine ecosystems. However, studies on MPs in estuarine and coastal ecosystems of Bangladesh are very limited. Here, we conducted the first study on abundance, distribution, characteristics, and risk assessment of microplastics in the sediment of Karnaphuli River estuary, Bangladesh. Microplastic particles were extracted from sediments of 30 stations along the estuary by density separation and then enumerated and characterized using a stereomicroscope and Fourier Transform Infrared (FT-IR) spectroscopy. In the collected sediment of the Karnaphuli River estuary, the number of MPs varied from 22.29 to 59.5 items kg−1 of dry weight. The mean abundance was higher in the downstream and left banks of the estuary, whereas the predominant shape, colour, and size of MPs were films (35%), and white (19%), and 1–5 mm (30.38%), respectively. Major polymer types were polyethylene terephthalate, polystyrene, polyethylene, cellulose, and nylon. MPs were found to pose risks (low to high) in the sediment of the estuary, with the highest risk occurring at one station near a sewage outlet, according to the results of risk analyses using the pollution risk index, polymer risk index (H), contamination factors, and pollution load index (PLI). The single value index, PLI, clearly demonstrated that all sampling sites were considerably polluted with microplastics (PLI > 1). H values showed toxic polymers, even in lower proportions, possess higher polymeric hazard scores and vice versa. This investigation uncovered new insights on the status of MPs in the sediments of the Karnaphuli River estuary, laying the groundwork for future research and control of microplastic pollution and management.

“…Meanwhile, Ali (2019) found that toxic metals in fish from the Karnaphuli River in Chattogram exceeded the maximum allowable consumption levels, highlighting the potential long‐term health effects and the need for further research. Furthermore, Uddin et al (2020) extensively analyzed the Karnaphuli River's water quality and found poor water quality in 11 locations sampled over three seasons. In addition, Rahman, Rony, et al (2022) revealed the direct and indirect consequences of increasing urban temperatures on the population in major districts of Bangladesh, emphasizing the need for a strong framework to guide urban development and limit expansion into ecologically sensitive areas of the city (Bajracharya & Sultana, 2022).…”

The study analyzes the underlying reasons and ensuing consequences of Chattogram city's development in Bangladesh, which diverges from the principles of sustainable development. This research employs mixed-method approaches incorporating primary data to achieve its objectives. The primary data is based on a survey, interview, the author's experience, and participatory observation in Chattogram city. Furthermore, it critically examines the existing literature to develop a theoretical understanding of Chattogram city's sustainable development and its sustainable environmental nexus.The results indicate that the expansion of Chattogram city's urbanization and industrialization is proceeding at a rapid pace; however, it is occurring in an uncoordinated and unsustainable manner that neglects environmental protection. Consequently, the city's development falls short of aligning with environmental sustainability and is liable to induce negative ramifications on the environment, human health, biodiversity, and climate. The study pinpoints several factors contributing to environmental degradation, including environmental mismanagement, non-existence of a master plan, environmental illiteracy, absence of carbon emission objectives, and haphazard industrialization and urbanization. Importantly, the issue has been exacerbated due to the inadequate focus on sustainability in the developmental process. Therefore, the findings of this research indicate that a sustainable development perspective is required to comprehend and address the issue of environmental degradation in Chattogram city. In addition, the comprehensive sustainable development strategy and policy recommendations proposed in this study are likely to be efficacious in curbing environmental degradation in Chattogram and other developing cities.

“…Thus the nature of distribution of flora and fauna in the aquatic system are mainly controlled by the fluctuations in the physical and chemical characteristics of water body. Several workers all over the world have assessed physicochemical parameters of estuarine water all over the world to evaluate the level of pollution and the health of the ecosystem (Millero, 1986;Madson et al, 2012;Uddin et al, 2020).…”

The study of estuarine water quality plays an important role in evaluating and determining the pollution status and health of the water. Vaitarna River estuary is one of the important water bodies in the Palghar district. Entire stretch of the estuary was arbitrarily divided into three zones. Physical and chemical variables of water were monitored season-wise in the year 2016. In the present study, the entire stretch of estuary showed high values of Temperature, pH, BOD, C.O.D. Acidity, Salinity, Hardness and Sulphate different physicochemical parameters were studied in 3 stations of the estuary. There was no previous data from the Vaitarna estuary. The study revealed that one-year data (January 2016 to December 2016) shows good environmental conditions to differences in physicochemical characteristics within the permissible limit. It concluded that the water quality is good, and it is the responsibility of our society the importance of such water bodies to keep free from pollution. Because of the fishery point of view the local fishermen depend on this area of water resources.
