Comparative Studies on Few Shrubs, Herbs and Climbers for Accumulation of Elements at Zinc-lead-fluoride Mine Area at Chandidongri (Chhattisgarh), India

Abstract

In these studies were carried out on 20 plant species included shrubs, herbs and climbers. Out of 20 plant species, ten species are herbs viz., Achyranthus aspera, Aerua lanata andrographis paniculata, Celosia argentea, Eranthemum purpurascens, Hemigraphis hirta, Lenonotis nepetaefolia, Polygonum glabrum, Sida cordifolia, Turnera ulmifolia, five species are shrubs as Annona squamosa, Casearia graveolens, Elacodendron glaucum, Holarrhena antidysentrica, Woodfordia fruticosa, rest five species are climbers as Abrus precatorious, Butea parviflora, Gymnema inodorum, Olax imbricata and Ventilago calyculata. The concentration of the elements viz., Cu, Co, Ni, Pb, Zn, Cr, Fe, F and K₂O were estimated from washed plant leaves and young twig samples which were collected from mineralized and non-mineralized area's plants for comparison. Chemical analysis showed higher elemental concentrations in comparison with the non-mineralized area's plants. The growth distribution and toxic effects of plants of the mine area may be influenced by subsurface geology, reflecting the accumulation and toxic level of these elements in comparison of elemental composition of uncontaminated plant tissues.
