A survey could have been over on top sediment types of ten programs along side Feni River estuary was in fact analyzed so you’re able to profile the latest accumulation, source and you will pollution degrees of hefty precious metals. The results showed that an average content (?g grams-1) regarding seven picked heavier gold and silver observed the order from Mn () > Cr () > Ni () > Co () > Pb (six.47) > Ag (step one.09) > Since (0.85) > Hg (0.71), plus the levels varied spatially and you may seasonally that have apparently large account at up programs and you can inside the wet year. Tolerance pronaД‘ite Peruanski Еѕene impact attention (TEC) and you can possible impact focus (PEC) philosophy showed that the latest concentration of merely Ni and you will Cr have been browsing periodically exhibit unwanted effects on environment. Enrichment foundation (EF), geo-accumulation directory (Igeo) and contaminants grounds (CF) analyses revealed that Ag, Co and you will Hg was at the moderate so you’re able to higher contamination membership and you may new rests (As, Cr, Ni, Pb and Mn) had been from the no so you can lowest pollution account. Possible ecological exposure directory (PERI) also indicated that Ag, Co and you may Hg was basically the most prospective environment chance foundation are computed within this read area. Relationship matrix along side multivariate dominant parts research and team analysis recommend that Ag, Co, Ni and Hg came from anthropogenic present (agrochemicals, silver nanoparticles anti-bacterial representative, silver plating), whereas Since, Cr, Pb and you will Mn mainly came from absolute geological record. Thus the latest Feni lake is already a delicate and you will vulnerable state and you can one contaminants regarding SEZ will simply exaggerate degrees of pollutants on the lake inside Bangladesh.
Regarding the downstream influences, Teacher Ainun Nishat, an expert, mentioned to help you ‘The company Standard’ which he considered that “the fresh conformed-up on withdrawal from water is quite absolutely nothing inside the amounts.” He told me, “Since the lake has the very least circulate of 794 cusecs out of liquid actually into the lifeless season, the degree of water decideded upon getting detachment won’t have much perception.” Which statement was backed by an alternate pupil, Teacher AKM Saiful Islam of your Institute out of H2o and you will Flood, Bangladesh College or university from Technologies and you will Technical (Buet) who noted your agreed-up on water is indeed “little” and won’t possess much effects across the Feni Lake.
However the big bones from contention stays debated – creating a process having perfect measurement off withdrawal from the river. Already we have witnessed crappy bloodstream previously along side withdrawal regarding Farakka between the two places and it must be made certain that the exact same facts is not regular right here too. In short, signing on the MoU introduces vow that some type of water-revealing mechanisms was created for the remainder rivers also and you can would-be observed inside phrase and you can soul.

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 in order to its mandate throughout the 36th JRC appointment. A decision is actually drawn in the latest appointment that Ministers of H2o Sources of both regions would check out the internet in which developmental functions was indeed organized. This Shared Review of numerous cities out-of developmental and you will flooding shelter deals with preferred canals happened out of .”
A major an element of the lake circulates by way of Bangladesh plus the rock pollution when you look at the deposit info can get perspective serious risk so you’re able to environment and you may people fitness as a result of eating web
As per the present assistance, it takes about twenty five acres off belongings to prepare a special Economic Zone, as per the established advice. Nevertheless the belongings offered at Sabroom try less than the desired quantum. The brand new house on the market today into regulators within Paschim Jalefa village, where the SEZ would be put up, is hectares. Initiatives was basically drawn to own getting hectares even more property adjacent to the known area.
Starting off an effective SEZ was among BJP’s poll promises before the 2018 assembly election
The greatest ecological impact could be the too much age bracket out-of waste from the flowers established in SEZ, particularly in the plastic-oriented markets. We could bear in mind you to at the beginning of 1990s, recommended DuPont bush would not become established in Goa, notwithstanding taking the certified clearances, by way of vociferous resistance out of local people and you will environmentalists. Next, it might be nearly impossible to end the fresh new industries-generated waste typing regarding Feni river, given that despite all types of rules and controls it has got not satisfied achievements anywhere in India and it’ll has actually disastrous implications on riverine biota and you may communities and you may lake-surrounding environs downstream. Finally, although drinking water is being consumed the name regarding taking water supply to the city of Sabroom, but with the fresh facilities off SEZ right here, there will certainly feel a sea-change in liquids have fun with, as more and more liquid are required by industries from inside the SEZ, and you may once more neighborhood populace often face a liquids crisis when you look at the upcoming not very faraway. Fourthly, it’s basically noticed you to definitely no matter what sub-surface geology and you can characteristics regarding groundwater aquifer, the standard of below ground liquid deteriorates drastically due to leaching and you will percolation of several chemical compounds through the soil which often also negatively affects the brand new surface health.
