RETRACTED ARTICLE: Levels of Toxic Elements in Tea Brands Commercialized in Egypt Using Optimized Dual-Pulsed Laser-Induced Spectral Analysis Spectrometer
Retraction Note to: Biol Trace Elem Res (2018)
The authors are retracting this article  because they did not validate their results for the levels of lead, aluminium and zinc in the tea samples by comparing them with results obtained by a certified international reference laboratory for the same samples. Both authors agree with this retraction.The online version of this article contains the full text of the retracted article as electronic supplementary material.
