The Contaminated Level of 16 Polycyclic Aromatic Hydrocarbons in Green Tea, Black Tea, Oolong Tea and Pu-er Tea
Polycyclic aromatic hydrocarbons (PAHs) are the largest ubiquitous persistent pollutants considered of priority concern caused the mutagenic and carcinogenic effects.PAHs have been found in water, air, soil, and therefore also in food.PAHs could be uptaken and translocated by tea plant roots or leaves from atmosphere, water, and soil.Another contaminant pathway was reported through absorption of PAHs released from the burning pine firewood during drying stage of black tea processing.Several studies have been reported the PAHs levels in made tea and the concentrations were were reported with the range of 1.5-8800 μg kg-1.The aim of this study was investigated the contaminated level of PAHs in green tea, black tea, oolong tea and pu-er tea samples from China using GC-MS/MS.
