In 1982 the levels of lead (Pb), cadmium (Cd), vanadium (V), copper (Cu), and selenium (Se) were determined in hair of 231 four- to five-year-old children. The objective was to explore the feasibility of using metal-in-hair levels in groups of children as an indicator of environmental pollution. The study was carried out in four areas, which were assumed to differ in ambient pollution by metals. A questionnaire on personal data, socioeconomic status, intake of beverages, and life-style was completed by the parents. The metal-in-hair levels covered a large range. The variables pertaining to location together with sex, presence of a garden, and drinking of coffee and/or tea explained 32% of the variance of Pb, 24% of the variance of Cd, and 21% of the variance of V. The total variance explained by all measured questionnaire items was at best 38%. The location was the most important factor. Cu and Se levels did not differ between the locations.
1982年，对231名4至5岁儿童头发中的铅（Pb）、镉（Cd）、钒（V）、铜（Cu）和硒（Se）含量进行了测定。目的是探讨将儿童群体头发中的金属含量作为环境污染指标的可行性。该研究在四个地区进行，假定这四个地区的金属环境污染程度不同。家长们填写了一份关于个人数据、社会经济地位、饮料摄入量和生活方式的问卷。头发中的金属含量范围很广。与地点相关的变量，连同性别、是否有花园以及是否喝咖啡和/或茶，解释了铅含量方差的32%、镉含量方差的24%和钒含量方差的21%。所有测量的问卷项目所解释的总方差最高为38%。地点是最重要的因素。不同地点的铜和硒含量没有差异。
