| 中文摘要 |
| 本文参照OECD(经济合作与发展组织)的标准,以室内模拟条件,对杀虫双在土壤中的动态进行了淋溶试验。结果表明,杀虫双淋溶性极强,土壤中绝大部分杀虫双可被水淋溶,留在土壤中的也可随着水的不断加入而被淋溶出。土壤性质对淋溶影响很小,而流速、温度对淋溶影响较大。 |
| 英文摘要 |
| With reference to OECD-Chemicals Testing Guidelines, laboratory experiments were carried out to examine the leaching dynamics of dimethypo in soils. The results suggest that dimethypo possesses a strong tendency of leaching. Thus, most of the pesticide can leach through the soil columns. With the continuous addition of leaching water, all the pesticide in soil columns can leach out. Soil properties did not show great influence on leaching, while flow rate and temperature exerted remarkable effect on leaching dynamics of dimethypo. |
