Toxic heavy metal pollution of water is a major environmental problem, and there is no conventional remediation approaches and acceptable solutions. This study demonstrates the absorption capacity of water hyacinth for the heavy metal, lead. In tap water hyacinth was cultured and supplemented with 1, 5 and 10 mg/l of lead. They were harvested separately after 0, 15, 30, 45 and 60 days. Plant samples viz. roots, laminae and petioles containing lead were analyzed using atomic absorption spectrophotometer. Results indicated that the maximum accumulation by water hyacinth was noted in roots as compared to petioles and laminae. The accumulation of Pb in roots, petioles and laminae increased with initial concentration and also with the exposure period. It was concluded that the trend of overall accumulation of lead by the water hyacinth between the treatments, days and plant organs were in the following order: roots > petioles > laminae T3 > T2 > T1 > T0.60th>45th>30th>15th> 0 days.
