This research was conducted in order to ascertain whether green tea extract will chelate lead from coral calcium supplements. According to Ching-Ling Wie and workers, the existence of lead has been shown to be present in coral calcium from their oceanographic study of the Okinawa coast. Their oceanographic research determined the lead sedimentation rate to be greater then 1.0 cm per year in areas around Okinawa. The coral mined in this region absorbs high concentrations of lead, which is trapped in the coral's calcium matrix. After careful research in the literature for lead contamination in calcium supplements, it was apparent that studies involving coral calcium were lacking. Through the use of super-clean techniques and a Perkin –Elmer TM Atomic absorption spectrometer five different brands of coral calcium along with one brand of calcium carbonate were analyzed. This research resulted in finding lead in coral calcium supplements in statistically significant amounts. This research was continued to ascertain whether green tea extract was a viable method of extracting lead from coral calcium. A review of the literature revealed that polyphenols found in green tea extract would chelate lead. Through the use of a Perkin –Elmer TM Atomic absorption spectrometer five different brands of coral calcium along with one brand of calcium carbonate were digested with green tea extract and the resultant filtrates were analyzed. Results of this additional study revealed that chelation of lead in coral calcium supplements with green tea extract were statistically significant.
