AIR POLLUTION TOLERANCE INDEX OF Plantago major IN STEELWORKS AREA OF ZENICA, BOSNIA AND HERZEGOVINA

Atmospheric pollution is among the largest anthropogenic impacts on the ecosystem. In numerous studies it was observed that plants, especially those that grow in urban areas, are heavily influenced by different pollutants and their survival is correlated with structural and metabolic adaptation to stressful environmental conditions. Primary objective of this study was to determine the index of tolerance to air pollution (APTI) of plantain (Plantago major), on two locations in Zenica. The results indicated that index of tolerance to air pollution of P. major, APTI, is higher in individuals sampled from the contaminated site, than those in the control area

Phytoremediation of Cadmium Polluted Soils: Current Status and Approaches for Enhancing

Cadmium (Cd) is a heavy metal present in atmosphere, rocks, sediments, and soils without a known role in plants. It is relatively mobile and can easily enter from soil into groundwater and contaminate the food chain. Its presence in food in excess amounts may cause severe conditions in humans, therefore prevention of cadmium entering the food chain and its removal from contaminated soils are important steps in preserving public health. In the last several years, several approaches for Cd remediation have been proposed, such as the use of soil amendments or biological systems for reduction of Cd contamination. One of the approaches is phytoremediation, which involves the use of plants for soil clean-up. In this review we summarized current data on the use of different plants in phytoremediation of Cd as well as information about different approaches which have been used to enhance phytoremediation. This includes data on the increasing metal bioavailability in the soil, plant biomass, and plant accumulation capacity as well as seed priming as a promising novel approach for phytoremediation enhancing
