A survey could have been complete on top deposit samples of 10 programs along side Feni Lake estuary have been reviewed to profile brand new accumulation, supply and you will contaminants amounts of heavier gold and silver coins. The outcome revealed that an average articles (?g g-1) out-of eight chose heavier gold and silver followed the transaction away from Mn () > Cr () > Ni () > Co () > Pb (6.47) > Ag (step one.09) > Due to the fact (0.85) > Hg (0.71), and also the concentrations ranged spatially and seasonally having apparently higher membership within up station and you may for the rainy season. Threshold impression attention (TEC) and you will likely impact attention (PEC) philosophy revealed that brand new concentration of only Ni and you can Cr was basically browsing periodically display negative effects towards ecosystem. Enrichment foundation (EF), geo-buildup index (Igeo) and you may contamination grounds (CF) analyses showed that Ag, Co and you may Hg were during the moderate to large contaminants account and you may new rests (Just like the, Cr, Ni, Pb and Mn) have been at no so you’re able to reasonable toxic contamination accounts. Prospective environmental chance directory (PERI) plus showed that Ag, Co and you can Hg was the essential potential ecological risk factor getting computed within read urban area. Relationship matrix and multivariate dominating role research and class investigation suggest that Ag, Co, Ni and you may Hg originated anthropogenic sources (agrochemicals, gold nanoparticles anti-microbial representative, gold plating), whereas Because, Cr, Pb and Mn mostly originated from pure geological background. Therefore the fresh Feni lake is a sensitive and insecure condition and you can one toxic contamination away from SEZ will exaggerate amounts of emissions regarding the river inside Bangladesh.
Regarding your downstream has an effect on, Teacher Ainun Nishat, a specialist, mentioned to ‘The firm Standard’ he thought that “this new concurred-through to detachment of liquids is really nothing for the number.” The guy explained, “Because the river possess at least move from 794 cusecs out-of drinking water also inside the lifeless 12 months, the level of liquid arranged having withdrawal won’t have far perception.” It report was supported by a different sort of scholar, Teacher AKM Saiful Islam of your own Institute out-of Water and you may Flood, Bangladesh College out-of Technology and you may Technology (Buet) who indexed that the assented-up on liquid is really “little” and will not has far impacts along the Feni River.
Although biggest limbs out of assertion stays disputed – doing a system getting precise aspect of detachment regarding river. Already there have been crappy blood in earlier times across the withdrawal from Farakka between the two countries plus it have to be made sure the exact same story isn’t repeated here as well. In a nutshell, signing in the MoU brings up vow one a liquid-revealing components is made for the rest rivers as Ruska mladenke well and you will could be followed inside the phrase and you may heart.
To the text out-of MOU see Asia-Bangladesh Mutual Report throughout the Specialized Check out of Best Minister off Bangladesh so you can India, , Click
The idea of making a bridge first came up in 2006 and Bangladesh was sounded, which objected to it on the ground that being a transboundary river, it should be deliberated in the Joint River Commission. Later, a press release in India in 2007 stated – “Feni Lake has been added in order to their mandate from the 36th JRC conference. A choice is actually consumed in the brand new appointment that Ministers away from Drinking water Sourced elements of the nations carry out visit the websites where developmental works was indeed organized. This Combined Check of various urban centers out of developmental and you may flooding shelter deals with well-known rivers occured from .”
A primary an element of the lake streams using Bangladesh additionally the heavy metal and rock pollution from inside the sediment info get pose major risk in order to environment and you will human fitness using food web
As per the established recommendations, it will take about twenty five miles out-of house to arrange an alternate Economic Zone, according to the current advice. However the house offered at Sabroom are less than the desired quantum. The home currently available into regulators at the Paschim Jalefa village, where the SEZ might be developed, try hectares. Initiatives was in fact removed having getting hectares extra property next to the identified plot.
Installing regarding a great SEZ are one of BJP’s poll pledges ahead of the 2018 installation election
The largest environmental impression is the an excessive amount of generation of spend in the flowers created in SEZ, especially regarding the rubberized-dependent markets. We could recall that at the beginning of nineties, proposed DuPont bush would not feel established in Goa, despite delivering all specialized clearances, as a consequence of vociferous opposition of local people and you will environmentalists. Subsequently, it might be almost impossible to end the production facilities-produced waste typing regarding Feni lake, because the even with a myriad of laws and regulations and regulation it has got maybe not came across victory around India and it will has actually disastrous effects for the riverine biota and you will organizations and you will river-surrounding environs downstream. Finally, although liquid is being taken in the name off ingesting water-supply to the city of Sabroom, but with the latest facilities away from SEZ here, there is going to yes become a sea-improvement in liquid play with, as more and more drinking water are needed from the marketplace within the SEZ, and you can again your regional society will deal with a drinking water drama inside the coming not too distant. Fourthly, it is generally seen you to aside from sub-facial skin geology and you may nature away from groundwater aquifer, the quality of below ground liquid deteriorates drastically because of leaching and you may percolation of several toxins from floor which in turn in addition to adversely influences the fresh ground wellness.
