Water Hyacinth to Help Remove Chromium from Water
Heavy metal poisoning is a growing concern in many parts of the country. A new method for removing chromium-6, a highly toxic heavy metal, from waste water has been developed by a group of scientists from India and Ethiopia. They claim it to be low-cost and safe.

The new method uses water hyacinth, a weed known for its ability to spread rapidly over water bodies. It is used for cleansing polluted water bodies owing to its remarkable capacity of absorbing pollutants.

In the new study, hyacinth was made into a powder and then mixed with water containing chromium-6. The powder was allowed to settle down and after two minutes the liquid above the powder was removed and analyzed for chromium-6. It was found that chromium-6 levels decreased significantly in water.
