Abstract:

 

In this study, grown tomato samples were examined changes of pesticide active substances by two different methods in the artificial gastric liquid (AGL) medium prepared. In the first method, Trifloxystrobin and Imidacloprid pesticide active substances were sprayed on the tomato samples before the harvest period. Time-dependent change of the active substance of Trifloxystrobin; although initially 83.17 ng g-1, it was determined as 24.71 ng g-1 in 240 min. The concentration of this active substance was determined that decreased with time and the % change was 70.29. While Imidacloprid active substance initially was 10.20 ng g-1, it was determined as 10.32 ng g-1 at 240 min. It was determined that this active substance did not change between the first and the last concentration depending on the time. In the second method, 75 pesticide active substances were spiked to the tomato sample and the time-dependent change in the AGL medium was examined. The concentration of 10 active substances that above 70% of the change rate was determined that there was a statistical decrease depending on the time % changes in the range between 0-240 min. The concentration of 30 active substances in below 70% of the change rate was determined that did not a statistical decrease as depending on time. however, % changes were observed that there was a certain thought at different rates between the first and the last concentration after 240 min. The last 15 active substances 240 min concentrations were determined that increased of % changes compared to 0 min.
