Biochemical responses of Camellia sinensis (L.) O. Kuntze to heavy metal stress.

Journal of environmental biology, 2001
Three heavy metals-mercury (II), copper (II) and nickel (II), each at a concentration of 10 and 100 micrograms/ml, were tested for their effects on various biochemical constituents of tea leaves. Both NI (II) and Hg (II) decreased the phenolic contents, while Cu (II) increased it to some extent.
