| 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... |

| Zearalenonesolution was given to dams micesubcutaneouslyat a dose of30 mg/kg body weightat the age ofpregnancy 13 to 18 days.Control micewere given only sesameoil. Furthermore, damsmice were allowed todeliver their litter and pups were weanedon 21 days of age. The live birth index andviability of the F-1 offspring were recorded. Determination of fertility of the F-1 offspring were undertaken by mating interlitters. On days 18 of gestation, the F-1 offspring were killed by cervical dislocation. The observation was performed on the number of live or dead fetus, embryo resorption, the number of implantation and the percentage of gestation loss. The result revealed that administration of zearalenone on days 13 to 18 of gestation caused a significant decreasein... |
