摘要：Contamination of the biosphere by heavy metals has increased sharply at the beginning of the 20th century,posing major environmental and human health problems worldwide. Metal pollution is considered hazardous to biologicalsystems because of their oxidative and carcinogenic potential. Phytoremediation technology has been receiving attentionlately as an innovative, cost-effective, and long-term alternative to the more established engineering methods used athazardous waste sites. Plants have the ability to take up harmful substances and then store or metabolize them. Thissuggests the possibility of phytoremediation of soil contaminated with organic, inorganic, and radioactive substances, all ofwhich are difficult to remove from soil with conventional methods. In the present study Physalis minima Linn a weed plantspecies used for zinc contaminated soils. This species belong to Solanaceae family of perennial herbs. The plant Physalisminima Linn was grown in pots filled with soil and solution of Zinc was administered to the plants for 60 days. The uptakeof heavy metals was estimated at 20 days intervals in roots, stem and leaves. A set of control experiment withoutapplication of heavy metal solution was also maintained. The order of accumulation of Zinc in Physalis minima wasrecorded as root> leaves> stem. The Bioconcentration factor and Translocation factor was also calculated. Based on theBCF and TF the weed plant species is a zinc accmulator.
