| A simple, rapid, and quantitative bioassay method was compared to a gas chromotography/mass spectrometry (GC/MS) procedure for the analysis of ametryn in surface and groundwater. This method was based on the activity of ametryn in inhibiting the growth of the primary root and shoot of germinating lettuce, Lactuca sativa L. seed. The procedure was sensitive to 0.01 ug/l and was applicable from this concentration up to 0.6 ug/l. Initial surface sterilization of the seed selection of pregerminated seed of certain root lengths, and special equipment are not necessary. So, we concluded that the sensitivity of the bioassay method is compatible with the chromatographic method (GC-MS). However, the study of the correlation between methods suggests that the... |
