Tea lives which possess a high surface area can be contaminated with atmospheric PAHs. The manufacturing processes may also introduce PAHs into tea lives. The aim of his study was to determine the contamination of black, green, red and white teas by PAHs. The total content … 2.7 microg/kg to 63,1 microg/kg for BaP. The analysed tea samples showed an increasing presence of PAH in the following order (mean value): black tea < red tea < green tea < white tea. … During tea infusion 1.6 % of total PAHs contained in tea was released into the beverage. … The concentrations of total 23 PAHs and BaP in tea infusions ranged from 332.5 ng/dm3 to 2245.9 ng/dm3 and 0.35 ng/dm3 to 18.7 ng/dm3 respectively.
