9,10-Anthraquinone deposit in tea plantation might be one of the reasons for contamination in tea.
9,10-Anthraquinone (AQ) was a new contaminant, with unknown sources, occurred globally in tea. European Union (EU) fixed the maximum residue limit (MRL) of 0.02mg/kg. The pollution source of AQ inExpand
