应用~(14)C示踪研究了久效磷在稻、鱼、土壤、田水中的残留。结果表明:该药在上述物体中均有残留,水稻收获时,在根、叶、茎、穗中的残留量分别为5.2248±0.4152、4.7928±0.7016、3.9895±0.6633、1.3042±0.1042微克/克干重;测得田水和土壤中的残留量为0.0012±0.0005微克/毫升,0.0241±0.0050微/克风干土。施用久效磷56天后,鱼体内的残留量为4.3964±0.9180微克/克干重。
The residues of monocrotophos in rice, fish, soil and field water were studied by using ~ (14) C tracer. The results showed that the drug residues in the above objects, the rice harvest, the residues in roots, leaves, stems, spike were 5.2248 ± 0.4152, 4.7928 ± 0.7016, 3.9895 ± 0.6633, 1.3042 ± 0.1042 μg / g dry Weight; residual water and soil measured measured 0.0012 ± 0.0005 micrograms / ml, 0.0241 ± 0.0050 micro / g dry soil. After 56 days of application of monocrotophos, the residual amount in the fish was 4.3964 ± 0.9180 μg / g dry weight.
