Studies on the residual levels of pesticide pollution in the sathiar reservoir
      
However, the levels of all these are still below criteria values for Malaysian aquatic life, indicating that organochlorine pesticide pollution is less of a problem than other organic or inorganic pollutants.
      
Since the extent of organochlorine pesticide pollution in Malaysian waterways is unknown except for isolated instances, a systematic survey has now been carried out.
      
Community IPM demand functions showed that individuals' knowledge and awareness of pesticide pollution are crucial for implementation.
      
The result shows that the pesticide pollution is moderate in GTR and its tributaries, although pesticide residue values in a few sites are quite high when considering their endocrine-disrupting effects and chronic health effects.

This paper mainly presents the effect of electrostatic spraying on charged cotton plant under different voltages, measured by means of manual counting, photography, photoelectric colorimetry and tracer method.The results show that charged cotton plant has significant effect on adsorbability and systemic action of charged droplets, and are basically in agreement with theoretical analysis From the experiments, the authors come to the preliminary conclusion that spraying volume adsorbed by cotton leaves increases with not only voltage on nozzle but also that on cotton leaves Tests on the application of tracer atoms 35S show that the adsorbability of systemic pesticide on charged cotton is less than that on uncharged. On this account, it is possible to reduce volta-geon nozzle by a big margin with a certain adsorbability. This feature of systemic function can be applied effectively to fresh fruits preservation. and vegetables with short growth phase for weakening systemic pesticide pollution as well.

本文主要介绍在棉株带电的情况下,施行不同电压的静电喷雾,并采用雾滴计数法、摄影法、光电比色法以及示踪原子法等多种检测手段,测出了棉株带电后对荷电雾滴的吸附性能和内吸性能有明显的影响,并与理论分析基本相符。本试验的初步结论为:棉株表面吸附的喷液量不仅随喷头电极接触充电电压的提高而增加,并随棉株带电电压的加大而递增。示踪原子~(35)S的试验表明,棉株带电后对内吸农药的吸收量,比棉株不带电的低。这表明在相同吸附性能下,有可能降低喷头电极接触充电电压:而在内吸性能方面的特点,可能有效地应用于果品保鲜及生长期短的蔬菜上,以减少农药内吸性污染。

Authors researched the degradation of fenvalerate,permethrin,cypermethrin and deltamethrin in 3 vegetables.The half-life of the degradation of 4 Pyrethroids -1.4~3.1 days.The time of 90% degradation-4.4~10.2 days and the half-life of degradation of fenvalerate is most long.Authors originaly suggested to eva- luate the degree of pesticide pollution in vegetables with initial residues of pestici- des,Half-life of degradation and the food canitary standards,and recommended to research in detail the role of plant growth dilution,the initial residues of pes- ticides and the problem of pesticide residue in repeatedly harvest vegetables.

作者研究了杀灭菊酯、二氯苯醚菊酯、氯氰菊酯和溴氰菊酯在青菜、小白菜、豇豆三种蔬菜中的残留降解情况,四种农药的降解半衰期为1.4~3.1天;降解90%期为4.4~10.2天,其中杀灭菊酯的降解半衰期最长。作者初步提出以农药起始残留量、降解半衰期和食品卫生标准来估计农药对蔬菜的污染程度,并建议对作物的生长稀释作用、农药起始残留量和多次采收性蔬菜的农药残留问题作详细的研究。
