Heavy metals pose significant threats to human health, particularly children. This study aimed to assess heavy metal pollution in children's playgrounds using surface dust as an indicator and to ascertain the associated exposure levels and health risks. A total of one hundred twenty dust samples were collected from the surface of playground toys in areas surrounding the cement factory in Bursa, Türkiye, on precipitation-free days. The heavy metal content of the samples was analyzed using ICP-MS. The average total concentration of heavy metals ranged from 2401 to 6832 mg/kg across the sampling sites, with the highest values observed at PG4, PG3, PG2, and PG1, respectively. The most commonly detected heavy metals in the samples included Cr, Mn, Fe, Co, Cu, Zn, Pb, Cd, As, and Ni. Statistical analysis revealed significant positive correlations (p < 0.01) among Cr, Mn, Fe, Co, Cu, Pb, As, and Ni, with Cu and Pb also showing correlation (p < 0.05). PCA analysis identified three principal components explaining 79.905% of the total variance. The Hazard Quotient (HQ) and Hazard Index values for heavy metals were found to be below the safe threshold (HQ < 1). Quantitative techniques such as the geoaccumulation index and enrichment factor are used to determine pollution levels at the sampling sites. Overall, the results indicate that cement factories significantly contribute to heavy metal pollution, with observed values varying based on proximity to the emission source.
重金属对人类健康，尤其是儿童健康构成重大威胁。本研究旨在通过表面灰尘评估儿童游乐场的重金属污染，并确定相关的暴露水平和健康风险。在无降水日，从土耳其布尔萨水泥厂周围地区的游乐场玩具表面采集了 120 个灰尘样本。使用 ICP-MS 分析了样品中的重金属含量。各采样点重金属的平均总浓度范围为 2401-6832mg/kg，PG4、PG3、PG2 和 PG1 的浓度最高。样品中最常见的重金属包括 Cr、Mn、Fe、Co、Cu、Zn、Pb、Cd、As 和 Ni。统计分析显示，Cr、Mn、Fe、Co、Cu、Pb、As 和 Ni 之间存在显著正相关（p<0.01），Cu 和 Pb 之间也存在相关（p<0.05）。PCA 分析确定了三个解释总方差 79.905%的主要成分。重金属的危害商（HQ）和危害指数值均低于安全阈值（HQ<1）。地质累积指数和富集因子等定量技术用于确定采样点的污染水平。总体而言，研究结果表明水泥厂对重金属污染有重大贡献，观察值因接近排放源而有所不同。
