A random survey was conducted to determine lead content in Indian tea and its decoctions. Lead content of various samples of tea was found to be between 0.4 to 1.6 ppm and in decoctions it was between 0. 002–0. 012 mg/liter. The effect of temperature and pH was also studied and it was found that larger amount of lead was leached out in the decoctions at low pH and at high temperature.
