这项研究的目的是确定在波兰严重拥挤的道路附近收集的人行道灰尘中的金属浓度，以便评估与人行道灰尘的摄入、皮肤接触和吸入有关的儿童和成人的非致癌和致癌健康风险。结果表明，华沙、克拉科夫、弗罗茨瓦夫和奥波莱的人行道粉尘污染严重，其中Sb、Se、Cd、Cu、Zn、Pb是交通排放指标。对不同接触途径确定的危险指数表明，儿童和成人的最大健康风险与摄入人行道粉尘有关。根据砷、镉、镍和铅计算，除华沙外，所有城市与儿童摄入人行道粉尘有关的致癌风险都超过了1 × 10（-4）的安全水平。儿童摄入的非致癌风险比皮肤风险高两个数量级，比吸入风险高四到五个数量级。成年人摄入人行道粉尘的非致癌风险与皮肤接触风险相当，而吸入风险则高出5个数量级。
The objective of the study was to determine concentration of metals in sidewalk dust collected in close vicinity to heavily congested roads in Poland in order to assess non-carcinogenic and carcinogenic health risk for both children and adults associated with the ingestion, dermal contact and inhalation of sidewalk dust. Results revealed that sidewalk dust from Warsaw, Krakow, Wroclaw and Opole is heavily contaminated especially with Sb, Se, Cd, Cu, Zn, Pb, considered as indicators of traffic emission. Hazardous indices determined for different exposure pathways indicated that the greatest health risk for both children and adults is associated with the ingestion of sidewalk dust. Carcinogenic risk associated with the ingestion of sidewalk dust by children, calculated for As, Cd, Ni and Pb exceeded safe level of 1 x 10(-4) in all cities except for Warsaw. Non-carcinogenic risk of ingestion for children was two orders of magnitude higher than dermal risk and four to five orders of magnitude higher than risk of inhalation. Non-carcinogenic risk associated with the ingestion of sidewalk dust by adults is comparable with dermal contact risk and five orders of magnitude higher when inhalation risk.
