j o,F:N!?~4r\0摘要:为了解赣江流域有机氯农药污染状况,采用索氏提取方法(Soxhlet Extraction,SE)和气相色谱法(GC-ECD),对所采集的18个底泥样品中10种有机氯农药(OCPs)的残留进行测定,并对其组分分布和来源进行了分析.结果表明,所有样品均检出10种有机氯农药,底泥中∑OCPs质量分数范围为11.813~39.197μg·kg-1,HCHs、DDTs质量分数范围分别为1.636~20.877μg·kg-1和5.590~14.092μg·kg-1,HCHs的质量分数低于DDTs,六氯苯(HCB)和七氯(Heptachlor)的质量分数相对较低,分别为0.229~6.940μg·kg-1和0.507~3.936μg·kg-1.组分分布特征分析表明,它们除了来自环境中的早期残留外,仍然具有大量新的外源HCHs和DDTs的输入,可能是新的林丹输入以及三氯杀螨醇的使用,这可能与近年来沿江农业的发展有关.水利论文@[pf g5MT"ru|
