Dynamic of degradation of lindane and its residual in soil 林丹在土壤中的残留动态研究
2.
In the research lindane and ddt have been selected as the representatives of persistent organic pollutants 研究了林丹和dd7在土壤中的降解残留状况。
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。

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 ) 。
