Blood lead levels have been monitored since 1974 and have shown a significant decrease (p less than 0.001) from 1978 to 1985 in 2830 subjects from Christchurch and environs. From a baseline in August 1978-81 to August 1985 blood lead levels in a population which had no relevant exposure to lead other than that from the general environment have fallen in adult males and females (greater than 17 years) by 42%, and in school and pre-school children greater than 9 months by 44% and 46% respectively. Reduction of blood lead has accelerated during the last three years. This can be linked to changes in dietary intake and clean up of lead in domestic and industrial environments. Over this decade the lead content of petrol (0.84 g/l) and petrol sales have remained unchanged.
自1974年以来一直在监测血铅水平，结果显示，1978年至1985年期间，来自克赖斯特彻奇及其周边地区的2830名受试者的血铅水平显著下降（p小于0.001）。从1978年8月至1981年的基线水平到1985年8月，除了来自一般环境的铅暴露外没有其他相关铅暴露的人群中，成年男性和女性（大于17岁）的血铅水平下降了42%，9个月以上的学龄儿童和学龄前儿童的血铅水平分别下降了44%和46%。在过去三年中，血铅水平的下降速度加快。这可能与饮食摄入的变化以及家庭和工业环境中铅的清除有关。在这十年中，汽油中的铅含量（0.84克/升）和汽油销售量保持不变。
