Biological Treatment of Contaminated Soil By Some Heavy Elements By Using Vegetable and Fruit Waste

The present study tested three types of waste (orang crusts, pomegranate crusts, banana crusts) for repairing some lab ecosystems through their ability to treat contaminated soil with some pollutants metals produced from some laboratory equipment. c = contaminated soil only that considered being a control test. both plants were exposed to heavy elements (pb, cd, cr) for three weeks and recorded the tolerance range weekly. all data recorded was triplicate. an atomic absorption spectrometer was used to estimate the metals concentrations. the results show primarily significant differences at each mineral concentration towards treatments during the tested period. this work aimed to find a friendly and straightforward way to limit contamination in the aqua ecosystem.
