Resumen
Camellia sinensis (Tea) has attracted attention of consumers and food manufacturers for its health benefits and physiological effects. Evidences are found that heavy metals are present in tea. Both metallic and non metallic elements are essential for human growth and development within certain permissible limits; harm to humans is expected due to change in this allowable limit. Twelve black tea samples (open and branded) were collected from market and subjected to analysis, using flame atomic absorption spectroscopy. The results showed that black tea available in market is made from leaves collected from different regions (different soil source), and have different capacity for accumulation of heavy metals. 6 15 1194 1196 Deanship of Scientific Research, King Saud University Riyadh [RGP-VPP-076] Deanship of Scientific Research, King Saud University Riyadh [RGP-VPP-076]
