摘要: Background: Tea is the most popular nonalcoholic beverage worldwide. In recent years, some Iranian studies have shown occurrence of toxic elements in fresh or dried tealeaves as well brewed tea. The present study aimed to ascertain health risks associated with exposure and essential element through black tea consumption Iran by systematically reviewing accredited articles field. Methods: order obtain relevant academic databases, search engines covering specifi c disciplines were searched for keywords, including tea, elements, heavy metals determination. Having provided complete list sound articles, being conducted was considered inclusion criteria. Exclusion criteria established failure provide information on validity parameters accuracy analytical methods. Choosing conducted, reliable studies, results concentration each utilized determination hazard quotient (HQ) given index (HI) then determined all study. Results: Among total two be reliable. Aluminum found abundant marketed Iran. Although HQ manganese highest among studied HI values both calculated less than 1. Conclusions: excessive intake should negligible However, related risk appeared more metals. Keywords: Black assessment, index, quotient,
