Since there are many different pathways from the technosphere to the environment, hexachlorobenzene (HCB) is widely distributed, supported by high mobility and high persistence. Several different assumptions were made about HCB inputs to air or water and, by simple calculations, potential HCB concentrations in water, air, sewage sludge and sediment were estimated. By comparing the results with measured environmental concentrations, maximum amounts of HCB released into the environment were estimated, and the relative importance of the water and air pathways appraised. Results showed that of the total HCB produced, the fraction that is released into the environment is substantially smaller than has been estimated. Despite the estimates of world-wide annual input of 10-100 t, it is well known that HCB is detected in relatively large amounts in most living tissues. This emphasizes the importance of the persistence of HCB, and of other environmental chemicals.
由于从技术圈到环境存在许多不同途径，六氯苯（HCB）分布广泛，这得益于其高迁移性和高持久性。针对六氯苯向空气或水的输入做了几种不同假设，并通过简单计算估算了水、空气、污水污泥和沉积物中六氯苯的潜在浓度。通过将结果与实测环境浓度进行比较，估算了释放到环境中的六氯苯最大量，并评估了水和空气途径的相对重要性。结果表明，在生产的六氯苯总量中，释放到环境中的部分比之前估计的要小得多。尽管估计全球每年的输入量为10 - 100吨，但众所周知，在大多数生物组织中都能检测到相对大量的六氯苯。这凸显了六氯苯以及其他环境化学品持久性的重要性。
