Organochlorine pesticides (OCPs) were analyzed in three different ages (half-, 1.5-, 2.5-year-old) for needles and semi permeable membrane devices (SPMDs) at three deployment periods from sea level to 1881 meter above sea level. Individual HCHs concentrations ranged between 1.4 and 129 pg/g fw depending on the age and sampling season while 2.5-year-old needles showed higher HCHs levels compared to half and 1.5- year-old. Correlation between elevation and HCH concentration in SPMDs was found but not in needle samples. Concentrations of HCHs in SPMDs indicated clearly cold condensation effect on accumulation in winter period and increased with altitude. Concentrations of DDTs in half and 1.5-year-old needles were lower than 2.5-year-old needles. The highest total concentration of DDTs was detected in 1-year-period SPMD. Higher concentrations were found in 2.5-year-old needles for other OCPs. Seasonal and altitude-dependent changes were not observed for other OCPs in SMPDs. Total accumulation of OCPs in SPMDs were found higher than in needles. On the contrary, an increased accumulation rate was observed for HCHs in SPMD. In general, Total concentrations of DDTs and HCHs were similar to total of other OCPs in all altitudes when dominating endosulfan wasnot taken into account in the computation of total concentration of other OCPs.

在从海平面到海平面以上188​​1米的三个部署阶段中，对针头和半透膜装置（SPMD）的三个不同年龄（半，1.5、2.5岁）中的有机氯农药（OCP）进行了分析。个体六氯环己烷的浓度范围为1.4至129 pg / g fw，具体取决于年龄和采样季节，而2.5岁的针头显示的六氯环己烷水平高于一半和1.5岁的针头。发现了SPMD中海拔与HCH浓度之间的相关性，但在针头样品中未发现相关性。六氯环十二烷中六氯环己烷的浓度明显表明冷凝结对冬季蓄积有影响，并随海拔升高而增加。一半和1.5岁针头中的滴滴涕浓度低于2.5岁针头。在1年期SPMD中检测到最高的DDT总浓度。在其他OCP的2.5岁针头中发现较高的浓度。对于SMPD中的其他OCP，未观察到季节性和高度相关的变化。发现SPMD中OCP的总积累量高于针头。相反，在SPMD中观察到六氯环己烷的积累速率增加。一般而言，在计算其他OCP的总浓度时未考虑到硫丹占主导地位的情况下，所有高度上DDT和HCH的总浓度与其他OCP的总浓度相似。
