Plant bioindicator for detection of lead (Pb) in drinking water

The quality of drinking water is increasingly deteriorated as a result of anthropogenic activities. Pb contamination is frequently reported at the water sources, threatening its safety for human consumption. The application of plants as bioindicators emerges as a useful alternative to detect Pb cont...
