A survey might have been over at first glance deposit samples of 10 stations along the Feni River estuary was basically examined so you can reputation the accumulation, supplies and you can toxic contamination levels of heavy gold and silver. The outcomes revealed that an average content (?g grams-1) out-of eight picked heavier gold and silver accompanied the transaction away from Mn () > Cr () > Ni () > Co () > Pb (six.47) > Ag (step 1.09) > While the (0.85) > Hg (0.71), and the concentrations varied spatially and seasonally with apparently high levels at the up stations and you can within the wet seasons. Tolerance impact amount (TEC) and you can probable impression amount (PEC) viewpoints revealed that the fresh concentration of merely Ni and you can Cr have been likely to periodically exhibit adverse effects towards ecosystem. Enrichment factor (EF), geo-buildup index (Igeo) and you may contamination grounds (CF) analyses revealed that Ag, Co and you can Hg were on reasonable so you can higher contaminants profile and the latest rests (As the, Cr, Ni, Pb and you will Mn) were in the zero to help you reduced toxic contamination levels. Possible ecological risk index (PERI) in addition to indicated that Ag, Co and you will Hg had been the quintessential possible environmental exposure grounds being computed inside learnt urban area. Relationship matrix along side multivariate prominent parts study and you can group studies recommend that Ag, Co, Ni and Hg originated in anthropogenic offer (agrochemicals, silver nanoparticles anti-microbial agent, silver plating), while Since the, Cr, Pb and you can Mn generally came from natural geological history. Thus new Feni river has already been a delicate and you may insecure condition and you will people contaminants out-of SEZ will only go overboard amounts of emissions about lake in Bangladesh.
Regarding the downstream has an effect on, Teacher Ainun Nishat, an expert, mentioned to ‘The organization Standard’ which he thought that “the fresh new concurred-up on detachment of liquids is extremely nothing when kissbrides.com mjesto tamo you look at the amounts.” He told me, “As the river has the absolute minimum circulate out-of 794 cusecs from liquid even in the lifeless seasons, the amount of water decided getting withdrawal won’t have far effect.” Which report is supported by an alternate student, Professor AKM Saiful Islam of your Institute regarding H2o and you will Flood, Bangladesh University of Technology and you will Technical (Buet) exactly who indexed the arranged-up on h2o is really “little” and won’t provides far results across the Feni River.
Nevertheless big limbs off contention stays disputed – performing a process to have particular dimension out-of detachment throughout the river. Already there’s been bad blood previously across the withdrawal regarding Farakka between them regions also it should be ensured that same story is not regular right here too. In a nutshell, signing for the MoU brings up promise you to definitely some kind of drinking water-revealing mechanisms will be created for the remaining rivers too and you can could be adopted in the phrase and you can spirit.
With the text off MOU come across Asia-Bangladesh Joint Report while in the Formal Go to from Best Minister regarding Bangladesh so you can 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 to their mandate on the 36th JRC fulfilling. A choice is taken in the new appointment your Ministers of H2o Types of both the regions create look at the web sites where developmental performs was held up. So it Joint Assessment of various metropolitan areas out-of developmental and you may flood security deals with common canals was held of .”

According to the established direction, it needs no less than twenty-five miles out of house to arrange a different sort of Economic Area, according to the established advice. Nevertheless the land offered at Sabroom is less than the mandatory quantum. The newest property on the market towards bodies at Paschim Jalefa community, where the SEZ will be setup, is hectares. Initiatives were removed getting acquiring hectares most home beside the known plot.
Setting-up away from good SEZ are certainly BJP’s poll guarantees prior to the 2018 construction election
The largest environment impact could be the excessive age group from waste on the flowers created in SEZ, specifically regarding plastic-based marketplaces. We are able to keep in mind that at the beginning of nineties, proposed DuPont bush would not end up being established in Goa, despite taking most of the specialized clearances, due to vociferous opposition away from residents and environmentalists. Furthermore, it might be nearly impossible to get rid of the fresh industries-made spend entering regarding the Feni river, once the even with all kinds of statutes and you can regulation it offers maybe not fulfilled victory anywhere in Asia and it will surely has actually disastrous ramifications into the riverine biota and you will teams and lake-related environs downstream. Thirdly, although the liquids has been consumed the name out-of drinking water-supply on the city of Sabroom, but with the fresh new business regarding SEZ right here, there may indeed become a sea-change in drinking water fool around with, as increasing numbers of liquids are required because of the industries for the SEZ, and once again the local population commonly face a liquid drama in the coming not very distant. Fourthly, it’s essentially observed one to irrespective of sub-facial skin geology and you may characteristics out of groundwater aquifer, the caliber of underground drinking water deteriorates considerably due to leaching and percolation of numerous chemical compounds through the surface which in turn together with adversely has an effect on brand new ground fitness.
