Based on sediment top quality guidelines (SQGs), the newest deposit examples was basically heavily contaminated that have Ag and you can Hg, and you can moderately having Co
A study could have been over on top sediment samples of ten stations along the Feni Lake estuary was indeed examined to help you reputation the newest buildup, supply and you can contaminants degrees of heavy gold and silver coins. The outcomes revealed that an average material (?g grams-1) away from seven selected heavy metals adopted your order away from Mn () > Cr () > Ni () > Co () > Pb (six.47) > Ag (step 1.09) > As (0.85) > Hg (0.71), datingsider der menn kan mГёte latinske kvinner in addition to density varied spatially and you can seasonally with seemingly higher account on upward stations and you can within the wet season. Tolerance perception concentration (TEC) and you may probable effect focus (PEC) viewpoints showed that the brand new concentration of simply Ni and you can Cr were probably periodically exhibit negative effects to your ecosystem. Enrichment factor (EF), geo-accumulation directory (Igeo) and contaminants foundation (CF) analyses revealed that Ag, Co and Hg have been at the modest so you can higher pollution levels and the newest rests (As the, Cr, Ni, Pb and you can Mn) have been at no so you can reasonable pollution accounts. Prospective environmental exposure list (PERI) as well as revealed that Ag, Co and you will Hg was basically by far the most prospective environmental risk factor are determined within studied town. Relationship matrix together with multivariate prominent part research and you may class research recommend that Ag, Co, Ni and you can Hg originated from anthropogenic source (agrochemicals, silver nanoparticles anti-bacterial agent, gold plating), while Once the, Cr, Pb and you may Mn mostly originated natural geological records. Thus this new Feni lake is already a fine and you can insecure state and you can any toxic contamination from SEZ is only going to overload quantities of emissions in the lake from inside the Bangladesh.
Regarding your downstream impacts, Professor Ainun Nishat, a specialist, said so you can ‘The firm Standard’ which he believed that “the fresh new conformed-on detachment away from h2o is very absolutely nothing in the quantity.” The guy informed me, “Just like the lake provides a minimum circulate regarding 794 cusecs out-of drinking water also from inside the inactive seasons, the degree of liquid arranged to have detachment won’t have far impression.” So it statement try backed by yet another pupil, Teacher AKM Saiful Islam of your Institute away from H2o and Flooding, Bangladesh University out-of Engineering and you will Tech (Buet) exactly who listed the agreed-up on h2o is indeed “little” and will not enjoys much issues over the Feni Lake.
Nevertheless major bones regarding contention remains disputed – starting a mechanism having right measurement from detachment about lake. Currently there’s been bad blood in earlier times along side detachment regarding Farakka between the two countries therefore should be made sure the exact same story isn’t regular right here as well. Simply speaking, signing associated with MoU introduces promise one to a h2o-discussing mechanisms would-be made for the rest streams as well and you may could well be used in the keyword and you will heart.

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 can their mandate regarding the 36th JRC fulfilling. A choice is drawn in the fresh new appointment that the Ministers off Liquids Types of the places perform go to the web sites where developmental performs was basically held up. It Mutual Evaluation of numerous towns and cities off developmental and you may flooding security deals with well-known streams happened regarding .”
A major a portion of the river circulates thanks to Bangladesh plus the heavy metal contamination from inside the deposit information can get pose major danger so you’re able to environment and you will peoples fitness as a result of dinner internet
As per the present recommendations, it will require at the very least twenty-five miles away from homes to arrange a separate Financial Region, as per the existing advice. However the property available at Sabroom is below the mandatory quantum. This new property currently available into authorities within Paschim Jalefa village, where in actuality the SEZ might be set-up, try hectares. Effort had been drawn to possess acquiring hectares a lot more belongings next to the recognized area.
Setting up regarding an excellent SEZ was certainly BJP’s poll claims ahead of the 2018 system election
The most significant ecological feeling is the extreme generation off spend on the flowers established in SEZ, specifically about rubber-dependent areas. We are able to recall one in early 1990s, advised DuPont bush did not become created in Goa, despite getting the specialized clearances, as a result of vociferous opposition away from local people and environmentalists. Subsequently, it would be extremely difficult to avoid the industries-produced waste entering on the Feni river, just like the even with all sorts of rules and you can control it has got perhaps not found achievements around India and this will has actually disastrous ramifications into the riverine biota and you can organizations and lake-related environs downstream. Finally, although liquids will be consumed in title out of consuming water-supply to the city of Sabroom, but with the latest place out-of SEZ right here, there’ll yes feel a sea-improvement in liquid explore, as more and more h2o are expected because of the opportunities within the SEZ, and you can again your neighborhood population commonly deal with a liquids drama inside upcoming not very faraway. Fourthly, it is fundamentally noticed you to aside from sub-body geology and you may character from groundwater aquifer, the grade of below ground drinking water deteriorates dramatically because of leaching and percolation of various chemical substances from the crushed which often along with negatively influences brand new ground fitness.
