'Eleven-plus' school examination scores were obtained for 851 Birmingham children residing since birth in a lead-polluted area and 1642 children residing in two similar but unpolluted areas. It was found that the children in the lead-polluted area actually scored higher on the average than children in the control areas. Within the area of lead contamination, children living closest to the source of pollution did not have significantly lower scores than children living further away. The results indicate that lead pollution of the magnitude reported in this investigation did not have a demonstrable effect on the mental capabilities of children in the affected community.
获取了851名自出生起就居住在铅污染地区的伯明翰儿童以及1642名居住在两个类似但未受污染地区的儿童的“11加”学校考试成绩。结果发现，铅污染地区的儿童平均得分实际上高于对照地区的儿童。在铅污染区域内，居住在离污染源最近的儿童的得分并不显著低于居住在较远地区的儿童。结果表明，本次调查所报告的铅污染程度对受影响社区儿童的智力没有明显影响。
