Abstract

Abstract

Residue of 18pesticides in 55teas from Fujian were determined using GC-MS/MS and LC-MS/MS.Quantities of the residual pesticides were compared to the recommended limits, such as MRL, EMRL and/or ADI, to assess the product safety.Eleven samples, including black and oolong tea, had detectable amounts of prohibited pesticides.Some unregistered pesticides were also present in 26samples.Bifenthrin was the most frequently detected pesticides among all.The safety assessment indicated that only the level of imidacloprid residue in a certain tea samples was lower than MRL.And, in general, the daily pesticide ingestion from average tea drinking was within the safety limits set forth by ADI.
