The study was carried out to determine the dissipation kinetics, persistence, and dietary risk assessment of tetraniliprole. Three applications of tetraniliprole were given at 50.00 g a.i./hac (X) and 62.50 g a.i/hac (1.25X) on chilli and brinjal at the fruiting stage. The recoveries in all the matrices were within the acceptable range of 70%–120%. The initial residues of tetraniliprole on chilli fruits were 0.379 and 0.593 μg/g and on brinjal fruits, the residues were 0.559 and 0.916 μg/g at 50.00 and 62.50 g a.i./ha, respectively. In red chilli, chilli field soil, and brinjal field soil the residues were below the limit of quantitation. The tetraniliprole follows first-order dissipation kinetics with the half-life (RL50) 1.58 and 1.99 days in chilli and 1.42 and 1.79 days in brinjal at X and 1.25X doses. In chilli, 9.89 and 12.11 days whereas, in brinjal, 10.75 and 13.25 days were recommended for harvesting the crops after the last application of tetraniliprole at X and 1.25 X doses, respectively. The hazard quotient values in chilli and brinjal for both males and females were below 1 indicating that the use of tetraniliprole does not cause any health risk to the consumers. 相似文献

Analysis of the wave properties of a new two-lane continuum model with the coupling effect 
下载免费PDF全文
下载免费PDF全文 A multilane extension of the single-lane anisotropic continuum model (GK model) developed by Gupta and Katiyar for traffic flow is discussed with the consideration of the coupling effect between the vehicles of different lanes in the instantaneous traffic situation and the lane-changing effect.The conditions for securing the linear stability of the new model are presented.The shock and the rarefaction waves,the local cluster effect and the phase transition are investigated through simulation experiments with the new model and are found to be consistent with the diverse nonlinear dynamical phenomena observed in a real traffic flow.The analysis also focuses on empirically observed twolane phenomena,such as lane usage inversion and the density dependence of the number of lane changes.It is shown that single-lane dynamics can be extended to multilane cases without changing the basic properties of the single-lane model.The results show that the new multilane model is capable of explaining some particular traffic phenomena and is in accordance with real traffic flow. 相似文献
