Abstract

More than 20 soil samples were collected from tea gardens of specialized tea towns in Guangdong, including Fenglang Town and Fengshun Town in Meizhou City, Changshan Town in Lianjiang City, Fenghuang Town in Chaozhou City. Content of 6 types of heavy metal (Cr, Cu, Pb, As, Cd, Hg) in tea garden soil was measured. On the basis of these, the safety was assessed. Results show that the comprehensive pollution index of these 6 types of heavy metal is lower than 0.7. According to Soil Pollution Grading Standard formulated by China Green Food Development Center, the soil is not polluted by heavy metal and remains at safety level. It proves that overall soil condition of specialized tea gardens in Guangdong Province is not polluted by heavy metal.
