Binding capacity and root penetration of seven species selected for revegetation of uranium tailings at Jaduguda in Jharkhand, India

Journal Article:

Abstract

Uranium from ores mined at the three mines - Jaduguda, Bhatin and Narwapahar (Jharkhand) - is processed in the mill and the waste emerges as tailings. The recorded radioactivity level in these tailings is very low, but to avoid any long-term effect of these tailings on the atmosphere, humans, cattle as well as native flora and fauna, the tailings are covered with 30 cm layer of soil. This reduces the gamma radiation and radon emission levels. However, to consolidate the soil covering the tailings on a sustainable basis, the area needs to be revegetated by plant species having shallow root systems, good conservation value and low canopy cover. Another important criterion for selection of species is that they should not have any ethnobotanical relevance to the surrounding villages. Considering these criteria, seven native plant species of forestry origin, viz. Colebrookea oppositifolia, Dodonaea viscosa, Furcraea foetida, Imperata cylindrica, Jatropha gossypifolia, Pogostemon benghalense and Saccharum spontaneum have been selected for experimental trials. We describe here the strategies adopted for consolidation of radioactivity in tailings, revegetation practices used and the ecological role of the selected species in consolidating the tailings.
