Ayurveda is a form of medicine practiced in India. In one study, 20% of U.S.- and Indian-manufactured Ayurvedic medicines purchased through the Internet in 2005 contained detectable levels of several toxic elements. Identify as many peaks as you can in the X-ray fluorescence spectrum of the Ayurvedic medicine. Use a question mark (7) for peaks that cannot be identified.
