Sunamganj: Bangladesh Atomic Energy Commission delegates did not found any Uranium or radioactive substances in haor water in their preliminary investigation.
Rather, the amount of Uranium found in haor water was rather lower than the general index of country-based Uranium.
However, they collected samples from several spots for further examination in Dhaka to prepare final report.
In very recent, excessive rain and flash floor causing the haor overflowed with water. As a result, crops were damaged and different aquatic animals including fishes started dying. Some mainstream media feared Uranium contamination in haor water causing crops damages and dying of aquatic animals as well as ducks.
However, Atomic Energy Commission found nothing harmful substances in the water like Uranium.
The commission suspected that excessive chemical fertilizer and pesticides could cause the death of fishes as well as decomposing of submerged crops could caused toxicities in the water which was harmful for aquatic animals.
Physical Science Atonomical Commission member Dr Dilip Kumar Saha of Bangladesh Atomic Energy Commission told the reporter at Sunamganj haor side on Sunday morning.
The delegations was also consisted of Bangladesh Atomic Energy Commission chief scientific officer Dr Debashish Paul and Bangladesh Chemistry Division chief Dr Bilkis Ara Begum.
Dr Dilip Kumar Saha said, “Some of you feared that Uranium contamination might caused the death of aquatic animals which is why we brought Radio-activity meter to monitor any kind of radio anomalies in water or other aquatic plants.”
“We found less than normal general index of country-based Uranium.”
That does mean, the death of fishes along with other aquatic animal was not for the presence of Uranium or other radioactive materials. The excessive fertilizer and pesticides used in the crops could react to form Ammonia gas in water which could reduce Oxygen in water causing death of fishes, he added.
He also said: “Rotting something in water could cause foul odor, change in color. We have collected on Saturday enough samples of water, dead fishes, dead ducks, water Hyacinth and sediments from several spots of the haor and sent those in Dhaka for further investigation.”
“We will investigate few more places on Sunday.”
Meanwhile, Dhaka University Botany Department five-member delegation also collected samples of water and aquatic plants to examine in their lab.
