| Abstract
| - A cup of tea that cheers can also be an important route of human exposure to pesticide residues. Itis important to evaluate the percent transfer of pesticide residue from dried (made) tea to tea infusion,as tea is subjected to an infusion process prior to human consumption. To investigate the pesticidetranslocation, 13 pesticides commonly used on tea were studied by subjection of fortified teas toinfusion. Analytes of interest were quantified by gas−liquid chromatography with nitrogen−phosphorus and electron capture detectors. Interestingly, water solubility of pesticides did notnecessarily indicate a shift of residues toward their preferential accumulation in infusion. Thepesticides with larger partition coefficient (Kow) values remained nonextractable in infusing water.Further, boiling for longer periods (extended brewing time) resulted in higher transfer of pesticidesto tea brew.
