| 摘 要： | 氰戊菊脂在水中的降解速度与酸碱度和光照强度有关,在碱性溶液中降解快,酸性及中性溶液中降解较慢,在蒸馏水中的光解速度,直射太阳光比散射光快。氰戊菊酯在室外池塘水中很快降解,水生生物的吸附作用是影响降解速度的重要因素,在夏季有水生植物和鱼的池塘水体中的降解半衰期为0.7～1天,在无水生植物和鱼的池水中降解较慢。

| Abstract: | The degradative rate of fenvalerate in water was relative with the pH and the illuminative intensity,which degraded rapidly in alkaline solution and slowly in acidity and neutral solution. The degradative half-life of fenvalerate in pH 9. 7,pH 8,pH7. 1 and pH 4 buffer solution under scattered light were 4. 1,9. 4,22. 5 and 14. 6 days (respectively. The photo-degradative half-life of fenvalerate in distilled water under natural direct solar radiation and scattered light was observed to be 3. 8 days and 7. 6 days in summer,respectivesly. The rapid disappearance of fenvalerate in outdoor pond that had plants and fishes with half-life of 0. 7-1 day in summer. |
