The tap water supply in Camelford, North Cornwall and environs was contaminated by aluminium and other metals in 1988. Richmond tests were routinely given before and after the pollution and here scores are compared between 39 children from schools in the contaminated area and 64 children from Cornish schools outside the polluted area. The study was retrospective and it was not possible to determine whether or how much polluted water individuals had consumed. No differences were found between groups either before or after the pollution accident nor was there any evidence for any sub-group of the polluted group which had been affected. The limits of conclusions which can be drawn from data available are discussed.
1988年，北康沃尔郡卡梅尔福德及其周边地区的自来水供应受到铝和其他金属的污染。在污染发生前后，里士满测试均按常规进行，此处对污染地区学校的39名儿童与污染地区以外康沃尔郡学校的64名儿童的测试分数进行了比较。该研究为回顾性研究，无法确定个体饮用了多少受污染的水以及是否饮用过。在污染事故前后，两组之间均未发现差异，也没有证据表明污染组中的任何亚组受到了影响。本文讨论了从现有数据中得出结论的局限性。
