铅浓度测定土壤样品收集在37个儿童日托中心位于大辛辛那提地区。土壤样本收集在外墙1.5米之内，并在每个儿童日托设施的室外游乐场的其余部分。土壤铅浓度被用作车辆排放物和铅基油漆铅污染的指标。通过电感耦合等离子体质谱法测定平均铅浓度。土壤铅浓度显着高于1.5米的外墙比其余的儿童日托中心的户外游乐区（P <0.05）。1980年以前建造的儿童日托中心的土壤铅浓度较高之间存在高度显著的相关性（P <0.01）。研究还发现，位于最近的州际公路2.5公里内的儿童日托中心的土壤铅浓度较高之间存在高度显着的关联（P <0.01）。这项研究的结果表明，有必要对儿童日托中心和其他设施中的铅污染表示关注，大量儿童每天都经常光顾这些设施。
Lead concentrations were determined for soil samples collected at 37 child day care centers located within the greater Cincinnati area. Soil samples were collected within 1.5 m of the exterior walls and throughout the remainder of the outdoor playgrounds of each of the child day care facilities. The soil lead concentrations were utilized as indicators of lead contamination from vehicle emissions and lead based paints. Mean lead concentrations were determined through Inductively Coupled Plasma-Mass Spectrometry. Soil lead concentrations were significantly higher within 1.5 m of the exterior walls than the rest of the outdoor play areas of the child day care centers (P < .05). There was a highly significant association between higher soil lead concentrations for child day care centers built prior to 1980 (P < .01). It was also found that a highly significant association exists between higher soil lead concentrations for child day care centers located within 2.5 km of the nearest interstate highway (P < .01). The findings of this research point to a clear need for concern about lead contamination at child day care centers and other facilities that large numbers of children frequent on a daily basis.
