Heavy Metal Content in Leaves of Ficus retusa Collected from Contaminated and Uncontaminated Sites in Northern Egypt: Mitigation of Toxicity by Washing Treatments
Journal Title: Universal Journal of Environmental Research and Technology - Year 2011, Vol 1, Issue 4
Abstract
Leaves of Ficus retusa were collected from three locations; suburban, urban and industrial in Northern Egypt. Concentrations of heavy metals in soils collected from the suburban site were lower than that collected from other sites. Plants washed with 1% soap showed better growth, higher chlorophyll content and higher photosynthetic rates than those remained unwashed or washed with tap water or 0.1N HCl. Our results indicated that washing treatments alleviated the phytotoxic effects of heavy metal pollution on plants.
