  1. The mean values followed by the same letter within the same column of each treatment are not significantly different (P > 0.05) using Tukey’s test
  2. aUnit of enzymes: CarE activity (nM p-nitrophenol/min/mg), GST activity (mM glutathione conjugated product/min/mg) and AChE activity (acetylcholinesterase/mg protein/min).
  3. bCF the correlation factor (acetone-treated group/chrysoberyl-treated group).
