Research in Biology
Environmental exposure to heavy metals such as lead pose a significant health threat. The goal of this project was to evaluate the effectiveness of Coriandrum sativum (Cilantro) as a potential lead (II), Pb2+, phytoremediator. C. sativumplants were allowed to grow for 43 days while exposed to with different amounts of lead nitrate, Pb(NO3)2. Lead exposure was accomplished by regular watering with a concentration series of lead nitrate solutions. The roots and shoots of these plants were separated and dried. Ground plant material was liquefied by nitric acid digestion. The amount of lead absorbed …
