- Abstract
The article reports on combined effects of lead and Humic acid on growth and lead Uptake of duckweed, Lemna minor. Humic substances, the end product of chemical and biological degradation of animal and plant residues, are the most widely distributed natural organic products on the surface of the earth. The complexation of humic substances and metal ions is extremely important in that this affects the behavior and mobility of metals in the environment. The capacity of aquatic plants such as duckweeds to remove potentially toxic heavy metals from water is well documented. Duckweeds were shown to take up heavy metals and survive in a highly stressed aquatic environment.
