Plant species sustaining under a polluted environment for long time are considered as potentially resistant species. Those plant species can be considered as an eco-sustainable tool used to bio-monitor and mitigate pollution. This study was carried out on total ten commonly available plant species to assess their anticipated performance index (API), Dust capturing capacity (DCC) and Metal accumulation index (MAI) in chromite mine and control area. According to Anticipated performance index (API) Macranga peltata, Holarrhena pubescens and Ficus hispida are highly tolerant species while Terminalia arjuna and Trema orientalis are intermediate tolerant species. Ficus hispida was also showed the highest dust capturing capacity (5.94 ± 0.43 mg/cm 2 ) and whereas Woodfordia fruticosa (1.03 ± 0.11 mg/cm 2 ) was found to be lowest. Metal accumulation index ranged from 17.29 to 4.5 and 6.38 to 1.94 at mine and control area respectively. Two-way ANOVA analysis revealed area wise signi cant differences between biochemical and physiological parameters. Also, result showed that the pollution level and heavy metal affected different biochemical and physiological parameter of plant species at mining area. The plant species with highest API, DCC and MAI value could be recommended for greenbelt development in different polluted area.

Concentrations of heavy metals (Cr, Cu, Fe, Mn, Ni, Pb, and Zn) accumulation were studied in the leaves of two medicinal plant species, namely Holarrhena pubescens, and Wrightia tinctoria, from two industrial areas and a control area. Our comparison study revealed that industrialization significantly increased the accumulation of heavy metals in both plant species. A comparison study in control and industrial areas exhibited that heavy metal accumulation was higher in the industrially affected area than in the control area. In the control area, both species accumulated the lowest heavy metal concentration. Where heavy metals concentration exceeded the permissible limit recommended by the WHO in both species of two industrial areas. Biochemical investigation specifies that in response to heavy metals accumulation, both species increased the activity of hydrogen peroxide (H2O2), malondialdehyde (MDA) content, the activity of enzymatic [superoxide dismutase(SOD) and peroxidase (POD)] and nonenzymatic [ascorbic acid (AsA)] antioxidant, but decreased the primary (soluble carbohydrate and total protein), secondary metabolites (phenol and flavonoid) content and free radical scavenging (DPPH) activity. These study indicate that industrialization potentially harms medicinal plants by reducing the efficacy of their medicinal property.
