AB  - The dynamics and residues of deltamethrin in a tea grown in an open field 
      ecosystem were investigated. The quantification was performed using gas 
      chromatography-electron capture detection (GC-ECD) and confirmed by gas 
      chromatograph-mass spectrometry (GC-MS) in selective ion monitoring (SIM) mode. 
      The method was validated using blank samples spiked at three levels and the 
      results showed that recoveries ranged from 87% to 101% with relative standard 
      deviations (RSD) ranging of 0.7-7.1%. The residues of deltamethrin were found to 
      dissipate following first order kinetics with half-life ranging between 3.04 and 
      3.54d for two different rates of foliar application. The deltamethrin residues 
      are present in the processed tea are not transferred into the tea infusion during 
      the infusion process, since their water solubility is extremely low. These 
      results can be utilized in formulating the spray schedule and safety evaluation 
      on deltamethrin tea crop.
