The Western part of the "Bassin Minier de Provence", a former coal mining area, is still occupied by old polluting industries such as a coal-fired power plant and an alumina factory. The identified pollution sources that raise more concern in the population are the emission of gases and dusts, as well as the storage of raw and transformed materials. In 2011, a preliminary survey was carried out in the area as the first step to an exposure and health risk-assessment study. This first survey intends to assess human exposure through ingestion and health risk associated with potentially harmful elements (PHEs) in ground-level dusts collected in recreational areas used by children. Dust samples were taken at 19 sites distributed across the study area, depending on the location of public parks, public gardens, playgrounds and schools. Pseudo-total concentrations of 53 elements were determined by ICP-MS. Bioaccessible concentrations were estimated using the unified bioaccessibility method. This study presents the results obtained for Al, V and Cr, which seem to be related with industry and show similar distribution patterns. PHEs presumably related to traffic or other urban pollution sources are not discussed in this study. The highest total concentrations occur in dusts near the alumina plant that have significant amounts of Al mineral phases (gibbsite and alumina). However, in these dusts only small fractions of the elements under study are in bioaccessible forms. The highest bioaccessible fractions occur in dusts collected near the coal-fired power plant. Further investigation is required to assess potential pathways of exposure and health risk in this area.
“普罗旺斯矿业盆地”西部曾是一个煤炭开采区，如今仍被一些污染严重的老工业占据，如燃煤电厂和氧化铝厂。在该地区，确定的污染源引起了人们更多的关注，这些污染源包括气体和粉尘排放，以及原材料和转化材料的储存。2011 年，作为暴露和健康风险评估研究的第一步，该地区进行了初步调查。该初步调查旨在通过收集儿童使用的娱乐区的地表灰尘，评估人类通过摄入而受到的暴露，以及与潜在有害元素（PHEs）相关的健康风险。在研究区域内的 19 个地点采集了灰尘样本，这些地点的分布取决于公园、花园、游乐场和学校的位置。使用电感耦合等离子体质谱仪（ICP-MS）测定了 53 种元素的总浓度。采用统一生物可利用性方法估计了生物可利用浓度。本研究介绍了 Al、V 和 Cr 的研究结果，这些元素似乎与工业有关，且具有相似的分布模式。本研究未讨论与交通或其他城市污染源有关的 PHEs。在靠近氧化铝厂的灰尘中，总浓度最高，这些灰尘中含有大量的 Al 矿物相（水铝石和氧化铝）。然而，在这些灰尘中，研究的元素只有一小部分处于生物可利用形式。在靠近燃煤电厂的灰尘中，生物可利用分数最高。需要进一步调查，以评估该地区的潜在暴露途径和健康风险。
