HEALTH RISKASSESSMENTOF RESIDUALTRACES OF ORGANOCHLORINE PESTICIDES (OCPs) IN INFUSSIONS FROM DIFFERENT TEA BAGS BRANDS IN JORDANIAN MARKET: GC/ECD WITH GC-EI/MS CONFIRMATION
Nine different tea brands samples were collected from the Jordanian market to track the pesticide residue levels in tea bags infusion and assess the potential health risks for consumers associated with tea consumption.The samples were analyzed by GC/ECD and confirmed by GC-EI/MS.The results based on a 200 mL mug of infused tea show that all of samples contain a-HCH,HCB,P-HCB,hepta-chlor,and_p,^>'-DDE; with heptachlor as most significant and encountered pesticide residue.The concentration of these pesticides was ranged from 1.44 pg/L for_p,^>'-DDE in T9 sample to 24.75 for heptachlor in T6 sample.Also,the summation of all OCPs (E OCPs) ranged from 22.87 pg/L for T2 sample (tea source Siri Lanka) to 35.94 pg/L in T6 sample (tea source India).It was found that heptachlor pesticide (2B-possible human carcinogen) exceeded the ADI limits with hazardous index (HI) values that ranged between 11.54 and 23.54 times the acceptable daily intakes (ADIs).This could develop chronic diseases in Jordanian population.Also HCB and heptachlor indicated cancer risk factors ranging from (2-5) *10" 5 and (4-7) xlO"4 respectively,which raises worries about possible carcinogenicity.These findings mandate posing more regulations regarding imported tea brands.
