Heavy metal uptake by plants from wastewater of different pulp concentrations and contaminated soils

There is a lack of information on the extent mineral extraction by plants from wastewater in arid and semi-arid environments developing countries. This research assesses performance Alhagi Mallow plant species for absorption heavy metals around tailings dam copper mine Iran. The industrial , known as pulp, site has different concentrations metals. In laboratory setting were cultivated irrigated with pulp (0, 20, 40, 60, 80, 100%) water. Heavy (chromium, manganese, cadmium, lead) accumulation aerial parts roots plants, in-situ soil dam, measured using an atomic spectrometer . Soil mapping based geostatistical methods was also conducted to show spatial pattern contaminants surrounds dam. Our results demonstrated that higher than parts, chromium cadmium uptake Mallow. showed lead manganese had dispersion compared chromium, high percentage being concentrated some hotspots. therefore, have potential remediate metal contaminated areas are recommended widespread use. However, frequent harvesting should be encouraged help reduce migration soils into surrounding environment. contributes cleaner production non-developing • Minesites concentration affect natural ecosystems. parts.
