| 3. | Lindane and ddt are typical persistent organic pollutants that have been used as pesticides in china for long period and that have caused extensive pollution
林丹和dd7是曾经在我国使用历史较长、造成污染较为普遍的持久性有机污染物。

| 4. | Lindane ddt deltamethrin and carbofuran to exert a certain influence to soil nematode density , nematode community structure in being cultivated in a pot and experimental , but not a decisive factor
林丹、 ddt 、溴氰菊酯和呋喃丹对模拟实验中的土壤线虫密度、线虫群落结构产生一定影响，但不是决定因素。

| 5. | 3 . it is exert through cultivated in a pot experiment cultivation for two month lindane and ddt original pesticide experiment after two month to get soil examine appearing value very low to find to observe . soil sampled form j and n farm which have used lindane and ddt for 40 years , the analysis result showed that the residue of the two pesticides are very high . lindane remains and reaches as high as 996 . 06 g kg - 1 , and ddt is 3382 . 75 g kg - 1 4
经过盆栽实验两个月的培养观察发现施加到土壤中的林丹与ddt原药在两个月的实验后检出值较低具有使用林丹、 ddt四十年历史的北京近郊j 、 n农场中两种农药残留较高，林丹残留最高可达： 996 . 06 g ? kg ~ ( - 1 ) ， ddt残留最高可达： 3382 . 75 g ? kg ~ ( - 1 ) 。
