From October 2012 to September 2013, air samples of hexachlorocyclohexanes (HCHs) were collected by polyurethane foam passive air samplers (PUF-PAS) from Caiban Village (CbV), Baihua Village (BhV), Bumeishan Village (BmsV) and Qitang Village (QtV), located in the rural region of Zhangzhou, Southeast China. The test results showed that four HCH isomers (α-, β-, γ-, δ-HCH) were ubiquitous with ∑HCHs concentrations ranging from 4.80 to 41.9 pg/m and a mean value of 17.7 pg/m. A seasonal variation was established in the air HCH levels. The highest ∑HCHs concentration was observed in the autumn whereas the lowest was detected in the spring. The ratio α/γ-HCH, which was used to identify the contamination source, revealed that air HCHs originated mainly from historical technical HCH residues and lindane usage. The health risk of inhalation exposure to atmospheric HCHs, assessed by the inhalation dosimetry methodology, was low and considered negligible for the local residents.
从 2012 年 10 月到 2013 年 9 月，在位于中国东南部漳州市农村地区的菜坂村（CbV）、百花村（BhV）、笔架山村（BmsV）和崎踏村（QtV），使用聚氨酯泡沫被动空气采样器（PUF-PAS）采集了六氯环己烷（HCHs）的空气样本。测试结果表明，四种 HCH 异构体（α-、β-、γ-、δ-HCH）普遍存在，∑HCHs 浓度范围为 4.80 至 41.9 pg/m，平均值为 17.7 pg/m。空气中 HCH 水平存在季节性变化。∑HCHs 浓度最高的是秋季，最低的是春季。α/γ-HCH 的比值用于识别污染来源，表明空气 HCHs 主要来源于历史上技术 HCH 残留和林丹的使用。通过吸入剂量学方法评估的吸入暴露于大气 HCHs 的健康风险较低，被认为对当地居民可忽略不计。
