“…However, the process is controversial and poses human health risks, safety as well as the environmental problems [5]. The seawater and surrounding soil in the coastal area of Sitakunda, Chittagong, Bangladesh, are heavily polluted due to ship scraping activities [4,7]. As the vessels are scrapped on open beaches, pollutants in different forms get accumulated first on the soil surface which incrementally migrates to the tidal and sub-tidal zone with the passing of time and subsequently deposited into the deep of the seawaters reaching the sediments.…”

Heavy metal pollution in agricultural soils and food crops around the ship breaking area is of great environmental and human health concern. In this work, we have spectroscopically determined the concentrations of Cd, Pb, Fe, Mn, Zn, Cr, Cu, and Ni in agricultural soils and commonly consumed vegetables, fruits, and rice grain collected from the Sitakunda ship breaking area of Chittagong, Bangladesh, in order to evaluate their contamination levels and probable human health risk with a multivariate statistical approach. Multivariate analyses such as principal component analysis and cluster analysis of the analytical data indicate a significant metal contamination in the samples which could be attributed to industrial activities such as ship breaking. The results of soil contamination evaluation indices such as enrichment factor, geo-accumulation index, and contamination factor demonstrated that the soils around the ship breaking area are mainly contaminated by Cd, Pb, Zn, and Cu while food crops were mostly contaminated by Zn, Cr, and Cu. The Pb contaminated the olive and teasle gourd while Cd contamination in rice grain was at the threshold limit for health hazard. Mn was slightly accumulated in banana. Transfer coefficient values of Cd, Zn, and Cu for almost all food crops were higher than other metals, and Cd showed the highest transfer. Estimated daily intake values for Ni exceeded the standard limit (1.3 μg kg −1 day −1). Target hazard quotient values of Cu, Zn, Pb, and Cd indicate that the local inhabitants who consume the contaminated food crops are being exposed to potential health risks.

“…The study area is also a hotspot of biodiversity and is situated at the intersection of many biogeographic divisions (Islam 2009). Owing to the accelerated urban growth, however, the area has experienced serious environmental degradation and a number of ecological problems, including deforestation, biodiversity loss, soil erosion, and changes to the carbon sink in aquatic ecosystems (Rana 2011;Hasan et al 2013;Banu 1995). In particular, the hills and associated forests that are closest to the urban fringe or near to villages are under the most severe anthropogenic pressures.…”

Examination of land use/land cover changes, urban growth dynamics, and environmental sustainability in Chittagong city, Bangladesh

As in many other developing countries, cities in Bangladesh have witnessed rapid urbanization, resulting in increasing amounts of land being taken over and therefore land cover changing at a faster rate. Until now, however, few efforts have been made to document the impact of land use and land cover changes on the climate, environment, and ecosystem of the country because of a lack of geospatial data and time-series information. By using open source Landsat data integrated with GIS technologies and other ancillary data, this study attempts to classify land use and create land cover maps, enabling postclassification change detection analysis. By this method, we document the spatial and temporal trajectory of urban expansion in Chittagong, the second largest city in Bangladesh, over a 36-year period. The findings suggest that, over the study period, 56 % of the land cover has undergone change, mainly because of the expansion of built-up areas and other human activities. During the 36-year period, the built-up area around Chittagong city has expanded by 618 %, with an average annual rate of increase of 17.5 %. As a result of rapid urbanization, the vegetated hills near urban development areas face serious threats of further encroachment and degradation, given that 2178 ha of hills have already been intruded over the study period. Because urbanization processes in Bangladesh have traditionally been viewed as the result of population growth and economic development, very little work has been done to track the potential growth trajectory in a physical or spatial context. This study, therefore, will contribute to the current understanding of urban development in Bangladesh from a temporal and spatial point of view. Findings will be able to assist planners, stakeholders, and policy makers in appreciating the dynamism of urban growth and therefore will facilitate better planning for the future to minimize environmental impacts.

“…Heavy metals, including sources from electrical wiring and systems (e.g., Cu, Pb, Hg), batteries (e.g., Pb, Ni and Cd), coatings, and paints (e.g., Cu, Zn, Cl, TBT) have been demonstrated to accumulate to greatly elevated concentrations within coastal waters and beach sediments where ship-breaking activities are practiced. For example, many studies have identified significantly elevated concentrations of metal concentrations, including in airborne particulate matter, nearshore and ground waters, and sediments, in ship breaking zones in comparison to nearby reference zones in countries such as Bangladesh, India, and Turkey [179,[181][182][183]. The severity of environmental impacts from breaking practices is reportedly varied according to the size and function of the ships [179,184].…”

Boating and shipping operations, their associated activities and supporting infrastructure present a potential for environmental impacts. Such impacts include physical changes to bottom substrate and habitats from sources such as anchoring and mooring and vessel groundings, alterations to the physico-chemical properties of the water column and aquatic biota through the application of antifouling paints, operational and accidental discharges (ballast and bilge water, hydrocarbons, garbage and sewage), fauna collisions, and various other disturbances. Various measures exist to sustainably manage these impacts. In addition to a review of associated boating- and shipping-related environmental impacts, this paper provides an outline of the government- and industry-related measures relevant to achieving positive outcomes in an Australian context. Historically, direct regulations have been used to cover various environmental impacts associated with commercial, industrial, and recreational boating and shipping operations (e.g., MARPOL). The effectiveness of this approach is the degree to which compliance can be effectively monitored and enforced. To be effective, environmental managers require a comprehensive understanding of the full range of instruments available, and the respective roles they play in helping achieve positive environmental outcomes, including the pros and cons of the various regulatory alternatives.
