Predicated on sediment high quality guidelines (SQGs), the fresh deposit examples were greatly polluted having Ag and Hg, and you may sparingly having Co
A survey could have been over on top sediment examples of ten programs along the Feni River estuary was assessed to reputation the latest buildup, present and you will toxic contamination amounts of hefty gold and silver coins. The outcome showed that the typical content material (?g grams-1) away from seven chose hefty gold and silver coins used the order away from Mn () > Cr () > Ni () > Co () > Pb (six.47) > Ag (1.09) > Since (0.85) > Hg (0.71), therefore the concentrations varied spatially and you can seasonally which have apparently high membership at the upward station and inside the wet season. Threshold feeling amount (TEC) and you will possible feeling concentration (PEC) philosophy revealed that new intensity of only Ni and you may Cr was going to periodically exhibit side effects for the environment. Enrichment grounds (EF), geo-accumulation list (Igeo) and you will contamination factor (CF) analyses indicated that Ag, Co and you can Hg was on average to help you highest toxic contamination levels and new sleeps (While the, Cr, Ni, Pb and you can Mn) have been at zero to help you reasonable contaminants profile. Possible environmental chance list (PERI) along with showed that Ag, Co and Hg were the most prospective environmental risk grounds getting calculated within this studied town. Relationship matrix combined with multivariate prominent role research and people investigation advise that Ag, Co, Ni and you can Hg originated anthropogenic sources (agrochemicals, silver nanoparticles anti-bacterial representative, silver plating), whereas Because the, Cr, Pb and Mn primarily came from natural geological history. Ergo new Feni river has already been a delicate and you may insecure condition and you will people contamination out of SEZ simply exaggerate quantities of pollutants regarding lake when you look at the Bangladesh.
About your downstream has an effect on, Professor Ainun Nishat, a professional, mentioned so you’re able to ‘The organization Standard’ that he thought that “brand new arranged-on withdrawal of liquid is really little when you look at the numbers.” He informed me, “Since lake have a minimum flow from 794 cusecs off liquids actually inside the inactive 12 months, the level of h2o decided to own detachment will not have much effect.” It report are backed by another college student, Teacher AKM Saiful Islam of your Institute regarding Water and Flood, Bangladesh School from Engineering and you can Technology (Buet) exactly who noted that agreed-abreast of h2o can be so “little” and does not has far effects along the Feni River.
But the significant limbs out-of contention remains debated – performing a mechanism for particular aspect out-of withdrawal from the river. Currently there’ve been bad blood prior to now over the withdrawal regarding Farakka among them regions and it also should be made sure that the same facts is not constant right here too. In short, finalizing with the MoU brings up promise one to a drinking water-sharing components was made for the remaining streams too and you may is accompanied in phrase and you can soul.

With the text message out-of MOU find India-Bangladesh Joint Report during Formal Go to away from Prime Minister from Bangladesh to Asia, , Follow this link
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 River has been added so you’re able to the mandate on 36th JRC fulfilling. A choice are used new fulfilling your Ministers out of Water Resources of both nations do visit the websites where developmental works have been organized. Which Joint Inspection of various places away from developmental and you will flooding safety deals with well-known streams occured from .”
A primary a portion of the lake flows owing to Bangladesh as well as the heavy metal contamination when you look at the sediment tips get angle serious danger in order to ecosystem and you can people health as a result of dinner online
According to the existing direction, it needs at least twenty five acres of home to arrange an alternate Economic Zone, according to the existing advice. However the house offered at Sabroom is actually less than the necessary quantum. Brand new house on the market today with the bodies during the Paschim Jalefa village, where in fact the SEZ will be set up, is hectares. Efforts were removed for obtaining hectares additional land adjacent to the understood patch.
Installing out-of a SEZ is one of BJP’s poll guarantees prior to the 2018 set up election
The most significant environment impression is the a lot of age bracket regarding waste regarding the vegetation created in SEZ, specifically regarding the rubber-mainly based marketplaces. We can keep in mind you to during the early nineties, suggested DuPont plant failed to getting established in Goa, despite delivering most of the formal clearances, courtesy vociferous opposition off residents and you will environmentalists. Next, it could be almost impossible to get rid of the production facilities-produced spend typing on the Feni lake, as despite all kinds of statutes and controls it has not found achievement around Asia and this will provides devastating implications towards riverine biota and teams and you may lake-related environments downstream. Finally, although water has been drawn in title out-of consuming water supply into the town of Sabroom, but with the new institution regarding SEZ here, there will yes end up being a-sea-improvement in drinking water have fun with, as increasing numbers of liquid are required by the markets from inside the SEZ, and once again the local inhabitants commonly deal with a h2o crisis inside coming not faraway. Fourthly, it’s fundamentally noticed one to irrespective of sub-skin geology and you may character of groundwater aquifer, the grade of underground h2o deteriorates drastically on account of leaching and you will percolation of several agents from the floor which often plus adversely influences this new surface wellness.
