Impact of oil spill in the Bangladesh Sundarbans
International Journal of Fisheries and Aquatic Studies 2017; 5(5): 365-368
The Sundarbans is the largest mangrove forest of the world which is a part of the world's largest delta formed by the rivers Ganges, Brahmaputra and Meghna. Different marine vehicles use this channel as transportation route and causes accidents but very few studies focused on this issue. After a devastating oil tanker accident on 09 December, 2014 based on field work this study identifies the character of the spilled oil, range of the spillage, impact of spillage on aquatic environment, mangrove and human. This study makes a contribution to present adverse impact of oil spillage through vehicle transportation along the Sundarbans. Alternative river transportation routes must be launched from Mongla port to other parts of the country as soon as possible. Training, equipment and experience will improve the response to environmental emergencies and reduce the impacts on local communities and ecosystems.
The Effect of Oil Spill on the Sundarban Mangrove Forest of Bangladesh
CENTRAL ASIAN JOURNAL OF THEORETICAL AND APPLIED SCIENCES, 2023
The best mangrove woodlands on this planet is a region of the planet's finest delta molded by the streams Ganges, Brahmaputra, and Meghna. One-of-a-kind marine cars use this channel as a transportation route and cause setbacks, but no longer loads of examinations targeted this problem. On December 9, 2014, an oil massive hauler setback within the Sundarbans of Bangladesh provoked the appearance of approximately 358,000 liters of widespread gasoline oil into the circulation and mangrove climate. 500 thousand humans are sincerely and by idea structured upon the Sundarbans for their positions. Attributable to streaming systems, oil showed up at little creeks, channels boondocks flooring. Thick stupid radiator oil is stored money on the soil of intertidal zones, woodlands flooring, plant life leaves, stems, floating natural items, roots pneumatophores, and many others. A large part of the surfaces of the streams, springs and streams of the Southeastern piece of the Sundarbans had been included through the thick oil spills. It's miles met an affiliation of streaming channels, streams streams. It is covered an area of 6000 km2 of which 3956 km2 of mangrove woods grounds and extra than 1800 km2 of water bodies. This perceives the individual of the spilled oil, the quantity of the spillage, and the effect of the spillage on the maritime surroundings, mangroves, and individuals. In which the hazardous components within the Sela stream water checks outperformed pretty a long way set through the Prosperity affiliation (WHO) with a dropping solicitation of Co > Cd > Pb > Ni independently. Considering the water best file (WQI), metal defilement report (MPI), and steel nice rundown (MI), the Sela flow's water is not sensible for drinking anyway may be used for flooding agrarian and vegetable yields. This look discovered that the stream residue had higher polluting component (Cf) values for series, slight characteristics for Pb, Cr, Cu, Zn, Mg, and As, and inferior qualities for Mn, Fe, Ca, Na, and k. The mark of the audit is to perceive and examine the community of the Sundarbans and its on their occupation with the hazard regarded through the Sundarbans in step with reliable and further created vessel traffic the board, making plans, discernment equipment and enjoy, that allows you to chip away at the response to regular emergencies and lessening the consequences for adjacent groups and the herbal framework.
Ecological Effects of Oil Spill on Bangladesh Sundarbans Biodiversity
ECOLOGICAL EFFECTS OF OIL SPILL ON BANGLADESH SUNDARBANS BIODIVERSITY
On December 9, 2014 approximately 94,000 gallons (78,271 Imperial gallons) of heavy furnace oil spilled into Shela River, which is considered as an important river of the Sundarbans mangrove forest ecosystems. This was the largest ever oil spill incident into the coastal mangrove forest ecosystem of Bangladesh Sundarbans. Vast number of ecologically important animals and plants populations is in great threats after this massive oil spill accident. The spread of oil and its biological effects is documented immediately. Intertidal mangroves plants, river grasses, algae, and associated invertebrates were badly covered by oil and some of them died soon after. The death of Irrawaddy Dolphin (Orcaella brevirostris), Oriental Samll-clawed Otter (Amblonyx cinereus) has been reported because of oil spill. The presence of White Rumped Vulture (Gyps bengalensis) over the Sundarbans sky also indicated the large scale death of wild fauna. The secondary effect of oil spill is always much greater than the primary effects. So, proper initiatives should be taken in long run to protect the biological communities of Sundarbans.
2012 UBT International Conference
Visok a oilfield was explored in 1963 through the well G-622. In this oilfield had been drilled more than 170 production wells. Through all this years of its exploitation, mainly because of the outdated technology, the environmental pollution reached really dramatic values. The pollution extends on the Visoka village, affecting so the life for the entire community. The oil spills, the gas emissions and the formation water affected and polluted and-killed‖ the Gjanica River, its delta and the Adriatic coast in the Semani beach. Due to the technology and the co mpletely wrong policies, used in the past, the wells had been equipped with a pit, whose actually are filled with oil, water and solid wastes. Now these mixtures are more similar with TAR's. This is the main evidence which proves that, the area had never been cleaned up properly. Actually the reservoir had been given in use to a foreigner company, based in a petroleum agreement. The concessionary has already preparing the rehabilitation plan. Based on the best international experience the cleaning up ways will be based on the oil spill treatment, mainly through dispersants, the water treatment through dispersants, filtrations processes and reinjection and the emissions cleaning up mainly through reinjection. The polluted soil will be treated through thermal methods, or will be deposited in a closed landfill. Evaluations, calculations and spatial distribution of the oil spills of the Gjanica River and Adriatic Sea are presented in this paper.
Study Of Impacts Of Oil Spill On The Sundarbans Mangrove Forest Of Bangladesh
Journal of the Asiatic Society of Bangladesh, Science, 2015
Studies were carried out on the recent oil spill in the Sundarbans of Bangladesh to find out the immediate impacts on the ecosystem of the Sundarbans after oil spilling. More than 500 km 2 areas out of the total study area have been affected seriously by the oil spill contamination on 9 December 2014. Recorded data of the physico-chemical conditions, oil content, productivity, diversity and abundance of phyto-zooplankton and benthos of water, and oil content in soil indicate that the water and soil of the Eastern part of the Sundarbans were polluted by the oil contamination. Results also indicate that seedlings, mangrove algae, eggs and hatchlings of commercially valuable fishes, mudskippers, mud crabs, snails, monitor lizards were affected due to oil spill. Regeneration of the Sundri trees; intertidal zone bird-'Masked finfoot', common birds, fishing cat, otter, dolphins, crocodile would be affected due to the oil spill. Long term monitoring, in depth research and proper implementation of all rules and regulations are necessary to save the fragile ecosystem of the Sundarbans-the UNESCO declared world heritage site.
REVIEW ON THE SUNDARBANS DELTA OIL SPILL: EFFECTS ON WILDLIFE AND HABITATS
Review on the Sundarbans Delta Oil Spill: Effects On Wildlife and Habitats, 2016
Recently, Sundarbans aquatic ecosystems are suffering escalating impacts caused by oil spill. The hydrological connectivity of aquatic ecosystems in the Sundarbans Delta makes them highly sensitive to a broad range of anthropogenic activities. On December 9, 2014 approximately 94,000 gallons (78,271 Imperial gallons) of heavy furnace oil spilled into Shela River, which runs through the Sundarbans. Intertidal mangroves plants, river grasses, algae, and associated invertebrates were badly covered by oil and some of them died soon after. The death of Irrawaddy dolphin (Orcaella brevirostris), Oriental samll-clawed otter (Amblonyx cinereus) has been reported because of oil spill. The presence of White rumped vulture (Gyps bengalensis) over the Sundarbans sky also indicated the large scale death of wild fauna.
