Comparison of component area and their concentrations of extracted samples washed by tapwater (TW) and magnetically treated water (MTW) comparing to control (no pesticide contamination).

Zar [50] was used as the standard statistical reference text. Based on three replications (n = 3, means ± standard errors) of independent vegetable samples [50]. The concentrations were compared to Minimum Residual Load (MRL) on a pass/fail basis. The MRL for Malathion® is 3.000 mg L-1 [39]. The controls had no detectable Malathion ® but the sprayed vegetables failed the MRL criterion (p≪ 0.001, t-test compared to guideline) [50]. Only the control vegetables and the Malathion ®-sprayed vegetable washed with MTW passed MRL criteria based on students t-test compared to the guideline threshold value (p ≪ 0.001) [50].
