ABSTRACT

 

Arsenic is a carcinogen and a potential health hazard known to produce skin, bladder, and lung cancers. A very large segment of the population living in and around Lahore and other cities of the Punjab in Pakistan is facing a threat from contaminated ground water having dangerously high levels of arsenic. The present research has shown the biomass of Calotropis procera roots and aerial parts to bring the level of arsenic in arsenic contaminated water to the EPA standard within very short time and more effectively then biomass of roots and aerial parts of Pteris vitata and Eichhornia crassipes. The rate of removal of arsenic from contaminated water by roots of Calotropis procera was determined as a first step towards developing a safe, easy, indigenous and practical method of arsenic removal.
