Concentrations of HCH and DDT in soil, water and whole blood were determined in two areas under malaria control. These were, (i) bioenvironmental control of malaria at BHEL, and (ii) residual spraying of insecticides in rural and urban area of Bahadrabad PHC of Hardwar district. Mean concentrations of HCH in soil and whole blood samples from BHEL was 2.26 micrograms/kg and 1.20 micrograms/l and from Bahadrabad 61.12 micrograms/kg and 24.3 micrograms/l respectively. Similarly, the mean concentration of DDT in soil and whole blood from BHEL was 3.68 micrograms/kg and 4.71 micrograms/l, while in Bahadrabad 270.51 micrograms/kg and 38.13 micrograms/l respectively. HCH and DDT were never detected in any water samples from BHEL area, while the mean concentration of these compounds in water of Bahadrabad area was 0.18 and 0.07 microgram/l respectively. Residual level of HCH and DDT were 27 and 73.5 times higher in soil and 20.2 and 8.1 times higher in whole blood samples from Bahadrabad as compared to their corresponding values from BHEL respectively.
在两个疟疾防控地区测定了土壤、水和全血中六氯环己烷（HCH）和滴滴涕（DDT）的浓度。这两个地区分别是：（i）印度巴拉特重型电气有限公司（BHEL）的疟疾生物环境控制区；（ii）哈德瓦尔德区巴哈德拉巴德初级卫生保健中心（Bahadrabad PHC）农村和城市地区的杀虫剂残留喷洒区。来自BHEL的土壤和全血样本中HCH的平均浓度分别为2.26微克/千克和1.20微克/升，来自巴哈德拉巴德的分别为61.12微克/千克和24.3微克/升。同样，来自BHEL的土壤和全血中DDT的平均浓度分别为3.68微克/千克和4.71微克/升，而在巴哈德拉巴德分别为270.51微克/千克和38.13微克/升。在BHEL地区的任何水样中均未检测到HCH和DDT，而巴哈德拉巴德地区水中这些化合物的平均浓度分别为0.18微克/升和0.07微克/升。与BHEL相应值相比，巴哈德拉巴德土壤中HCH和DDT的残留水平分别高27倍和73.5倍，全血样本中分别高20.2倍和8.1倍。
