A study has been done at first glance sediment examples of ten programs across the Feni Lake estuary was basically reviewed so you can profile brand new buildup, source and you will pollution degrees of heavier precious metals. The outcome revealed that the typical information (?g g-1) regarding eight chose heavier precious metals adopted the transaction from Mn () > Cr () > Ni () > Co () > Pb (6.47) > Ag (1.09) > Since (0.85) > Hg (0.71), as well as the concentrations ranged spatially and you may seasonally that have apparently highest levels at the upward channels and you may from inside the wet year. Threshold feeling amount (TEC) and likely impression attention (PEC) viewpoints showed that the brand new intensity of only Ni and you may Cr was gonna periodically exhibit adverse effects toward ecosystem. Enrichment factor (EF), geo-buildup index (Igeo) and pollution factor (CF) analyses indicated that Ag, Co and you may Hg was indeed in the average so you can high toxic contamination accounts and you may this new sleeps (Since the, Cr, Ni, Pb and you will Mn) was in fact during the no to help you reduced toxic contamination accounts. Possible ecological exposure list (PERI) and additionally showed that Ag, Co and you will Hg were the essential potential ecological exposure grounds getting computed in this learnt urban area. Correlation matrix in conjunction with multivariate prominent parts analysis and cluster investigation suggest that Ag, Co, Ni and you will Hg originated in anthropogenic sources (agrochemicals, silver nanoparticles anti-bacterial representative, silver plating), while Due to the fact, Cr, Pb and you can Mn mostly originated from sheer geological record. Ergo this new Feni river is a fragile and vulnerable county and you will any contaminants away from SEZ will only exaggerate degrees of emissions throughout the lake for the Bangladesh.
Regarding your downstream affects, Teacher Ainun Nishat, a specialist, stated in order to ‘The company Standard’ which he considered that “the fresh assented-abreast of withdrawal of liquids is really nothing inside the number.” The guy said, Stare Еѕene su slobodne u vaЕЎoj blizini “As lake has the very least flow regarding 794 cusecs away from water even inside the lifeless seasons, the degree of water arranged for detachment won’t have far impression.” This report try supported by another pupil, Teacher AKM Saiful Islam of one’s Institute out-of Drinking water and you can Flooding, Bangladesh College out-of Systems and you will Technical (Buet) who indexed your assented-upon drinking water is so “little” and won’t features much results along the Feni Lake.
However the significant limbs away from assertion remains disputed – undertaking a procedure to own right dimension out of detachment in the lake. Currently there’s been crappy blood in past times along side detachment away from Farakka between them nations plus it must be made certain your exact same facts isn’t regular here also. Basically, finalizing of MoU brings up hope that some sort of water-sharing elements could well be made for the rest canals also and you may will be then followed when you look at the phrase and you may heart.
For the text message away from MOU look for Asia-Bangladesh Combined Report through the Official Check out off Best Minister off Bangladesh so you’re able to India, , Click here
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 is included so you can the mandate from the 36th JRC appointment. A decision are used brand new conference your Ministers away from Water Types of both regions manage look at the internet in which developmental functions was held up. That it Combined Evaluation of numerous cities out of developmental and you will ton security works on popular rivers was held off .”
A primary an element of the river circulates as a result of Bangladesh therefore the heavy metal and rock toxic contamination when you look at the deposit information can get angle serious danger to help you ecosystem and you will person health compliment of food online
As per the current assistance, it will require at the very least twenty-five acres out of belongings to set up an alternative Economic Zone, according to the existing direction. Nevertheless land available at Sabroom are below the desired quantum. The new home on the market today to your regulators on Paschim Jalefa community, where in fact the SEZ might possibly be build, is actually hectares. Effort was basically pulled getting obtaining hectares even more belongings near the understood patch.
Establishing of good SEZ is actually among BJP’s poll promises before the 2018 system election
The largest environment impression could be the continuously age group out of waste from the plants established in SEZ, particularly regarding the rubber-depending markets. We can remember one during the early 1990s, suggested DuPont plant decided not to feel created in Goa, despite providing all official clearances, thanks to vociferous resistance of local people and environmentalists. Secondly, it might be extremely difficult to stop new industries-produced waste typing from the Feni lake, as despite all types of regulations and you can regulation it’s maybe not found achievements around India and it surely will keeps disastrous implications towards the riverine biota and you will groups and you may lake-surrounding environs downstream. Thirdly, even though the water is being taken in title from sipping water-supply with the city of Sabroom, but with the facilities out of SEZ right here, there may indeed feel a sea-improvement in drinking water have fun with, as more and more water are expected from the marketplaces when you look at the SEZ, and you can once more nearby populace usually deal with a liquid crisis inside the future not so faraway. Fourthly, it’s generally seen one to irrespective of sandwich-surface geology and character of groundwater aquifer, the caliber of below ground liquids deteriorates significantly because of leaching and you will percolation of numerous chemical from the ground which often and additionally adversely influences this new surface wellness.
