Phytoremediation: Removing Lead Using Plants
City:St. Catharines, ON
School:Sir Winston Churchill
Abstract:This project explored whether common household plants can be used as an accumulator of lead. Plants from the Petunioideae sub-family were (Calibrachoa, Calitunia and Petunia) tested if they could accumulate lead. Calibrachoa accumulated the highest concentrations of lead. Traces of lead were also detected in the total proteins. It was discovered that Calibrachoa is a lead hyperaccumulator, and it absorbs lead possibly through metal-binding proteins.
