PAHs in some brands of tea



Polycyclic aromatic hydrocarbons (PAHs) are a class of environmental pollutants generated from incomplete combustion of organic materials. PAHs in tea have been studied for five locally available brands. Six to seven PAHs from list of 16 priority pollutants (US EPA) were found to be present in samples of various brands of tea. Benzo[a]pyrene (2A: probable human carcinogen) was found in two samples, and naphthalene (2B: possible human carcinogen) was found in all the tea samples.
