I was deeply concerned after reading the article titled “Uranium behind deaths in haors?” published by The Daily Star on April 21, 2017. It is worrying that this toxic heavy metal is contaminating our waterways and ecosystems. Unless it is tackled soon, this highly infectious and carcinogenic threat will start killing cattle living near the haor area. If it really is a uranium contamination then it is likely to remain in the soil, water, and plants. Eventually it will infect humans as well, creating catastrophic health hazards. The authorities must take immediate measures to protect us from this radioactive threat.
