Hirakund Wetland

Facts for Prelims (FFP)


Source: DTE

Context: 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.

The study also noted that the surrounding community indirectly consumes water from these wetlands by consuming foods like fish, rice, vegetables, and spinach grown in them.


Hirakud Reservoir (Ramsar Site)

It is the largest earthen dam in Odisha and started operating in 1957. Out of the known 54 species of fish from the reservoir, one has been classed as being endangered, six near threatened and 21 fish species of economic importance. It also provides important hydrological services by moderating floods in the Mahanadi Delta, the ecological and socio-economic hub of the east coast of India.
