Determination of Dichlorvos Contamination on Navel Orange Surface Using Vis-nir Spectroscopy

In order to ensure edible safety, more regard has been paid to pesticide contamination on agricultural product. Conventional techniques are used to measure pesticide contamination. However, the conventional analyses are not possible because of their destructive characteristic and the limitation of time and labor. Spectral technique can provide a rapid, nondestructive means to assess quality and safety of agricultural commodities. The simplicity, precision and accuracy of near infrared (NIR) spectroscopy technique, in combination with the advances in chemometrics, have extended its use to agriculture.
