The content of heavy metals--lead, cadmium, mercury, arsenicum was studied in 7 kinds of tea. Lead was detected practically in all studied kinds of tea, except for self-drinking long-lenved tea Sri-Lanka, cadmium was detected in Chinese Green coarse-grained tea, arsenicum was detected in all kinds of tea. However heavy metals content in all studied kinds of tea doesn't exceed their maximum allowable concentration.
