A study could have been complete on the surface deposit samples of 10 programs across the Feni River estuary had been assessed so you can reputation the buildup, provide and you may pollution degrees of hefty gold and silver. The outcomes indicated that the typical material (?g grams-1) from 7 selected hefty metals then followed the transaction from Mn () > Cr () > Ni () > Co () > Pb (6.47) > Ag (1.09) > Because (0.85) > Hg (0.71), plus the levels varied spatially and you can seasonally that have apparently high membership in the up programs and during the rainy 12 months. Tolerance impact attention (TEC) and you may possible perception amount (PEC) beliefs indicated that the fresh new concentration of only Ni and you can Cr had been attending sporadically display unwanted effects on ecosystem. Enrichment grounds (EF), geo-accumulation list (Igeo) and you can toxic contamination foundation (CF) analyses revealed that Ag, Co and you may Hg was basically from the reasonable so you’re able to high contaminants membership and new rests (As the, Cr, Ni, Pb and you may Mn) was basically at no in order to lower contaminants levels. Possible ecological exposure list (PERI) together with indicated that Ag, Co and you can Hg was basically more potential environment exposure grounds being calculated within studied area. Relationship matrix along side multivariate prominent component study and you will class study recommend that Ag, Co, Ni and you may Hg originated anthropogenic offer (agrochemicals, silver nanoparticles anti-microbial agent, gold plating), whereas Given that, Cr, Pb and you may Mn generally came from natural geological records. Ergo the newest Feni lake has already been a fine and you will insecure condition and you can one toxic contamination from SEZ only go overboard levels of emissions on lake within the Bangladesh.
Regarding the downstream impacts, Teacher Ainun Nishat, a specialist, stated to ‘The organization Standard‘ that he considered that “the newest conformed-abreast of detachment off liquids is really nothing into the wide variety.” The guy informed me, “Just like the lake keeps a minimum flow off 794 cusecs of h2o also inside the dry year, the level of liquids decided to have withdrawal will not have far feeling.” It declaration is actually backed by a different pupil, Teacher AKM Saiful Islam of your own Institute away from Water and you may Flooding, Bangladesh University from Technology and you will Technology (Buet) which detailed that agreed-upon liquids is really so “little” and does not provides far impact over the Feni Lake.
Nevertheless big limbs of assertion stays debated – carrying out a device to own direct dimensions out-of detachment regarding river. Already there’s been crappy bloodstream before along side detachment away from Farakka between them countries and it also must be ensured your exact same tale isn’t constant here too. In short, signing of MoU brings up pledge one to some type of liquids-discussing systems would-be designed for the remaining canals too and you will might possibly be observed during the keyword and you may heart.

Into the text message off MOU discover Asia-Bangladesh Shared Declaration throughout the Formal See away from Perfect Minister out of Bangladesh in order to Asia, , Click the 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 is included to its mandate throughout the 36th JRC fulfilling. A decision are taken in the fulfilling that Ministers of Liquid Sources of both places manage visit the internet in which developmental performs was basically held up. It Shared Check of various places out-of developmental and you may flood cover works on well-known canals occured of .”
A major an element of the river flows thanks to Bangladesh together with heavy metal and rock contamination into the deposit info get angle significant possibilities in order to environment and you will human health compliment of dinner websites
According to the established guidance, it takes no less than 25 acres out of house to arrange a different Monetary Region, according to the current advice. Nevertheless homes available at Sabroom try lower than the mandatory quantum. Brand new belongings on the market towards government from the Paschim Jalefa village, the spot where the SEZ was build, is actually hectares. Effort have been pulled getting obtaining hectares most house beside the identified plot.
Creating regarding good SEZ is actually certainly BJP’s poll promises ahead of the 2018 set up election
The greatest environment perception could be the too-much age bracket out-of spend on the vegetation established in SEZ, especially throughout the rubberized-centered marketplaces. We are able to keep in mind one to at the beginning of nineties, advised DuPont plant couldn’t end up being established in Goa, in spite of delivering all official clearances, owing to vociferous opposition of local people and environmentalists. Secondly, it might be extremely difficult to end the new factories-generated spend typing in the Feni lake, as even after all sorts of laws and you may regulation this has not met profits around Asia and this will keeps devastating ramifications on the riverine biota and communities and river-nearby environments downstream. Thirdly, though the liquid will be drawn in title from sipping water-supply for the city of Sabroom, but with the new facilities off SEZ here, there is going to indeed become a sea-improvement in h2o use, as increasing numbers of liquids are needed from the marketplaces when you look at the SEZ, and you will again your neighborhood population usually face a liquids drama from inside the future not faraway. Fourthly, it’s fundamentally seen that despite sub-body geology and you may character out-of groundwater aquifer, the grade of below ground h2o deteriorates substantially because of leaching and you will percolation of numerous agents from the ground which often including negatively affects the new crushed fitness.
