摘要
研究了铁灭克农药(Aldicarb)对地下水污染的影响,同时用美国环保局提供的PRZM模型进行模拟.结果表明,田间试验的实测值与PRZM的模拟值吻合良好.在本试验条件下,棉田使用铁灭克对地下水无污染影响.研究表明,PRZM模型可以用来模拟铁灭克农药在其它平原地区使用时对地下水的影响。
The effect of aldicarb on ground water quality after being applied to coastal alluvial sandy loam in Nantong area was studied and simulated with PRZM Model provided by USEPA.The measured data were closed to the simulated results. The depth to which aldicarb could be leached did not exceed 60cm. Almost all aldicarb degraded in root unsaturated zone in 60 days. Under the experimental conditions, applying aldicarb to cotton fields did not cause ground water contamination.
