Hirakund Wetland : Cancer-Causing Heavy Metals Detected

  • A study has revealed high levels of cancer-causing heavy metals, including lead and
    chromium, in eight wetlands in Odisha, with Hirakud being one of them.
  • These heavy metals, which result from human activities such as urbanization,
    industrialization, and agriculture, can enter crops through the soil and subsequently be
    consumed by humans.
