Metallurgical industrial processes have been reported to cause higher aluminium (Al) exposure in humans through plant food intake due to higher soil Al content and acidification of soil resulted from industrial acid rains. Mandi-Gobindgarh is critically environmentally polluted steel industrial town in India in which Al is used for deoxidation, grain refining and alloying in steel production. The Al processing has been reported to release Al into the environment, and therefore present study was undertaken to investigate the dietary Al exposure in children and adult population of Mandi-Gobindgarh from consumption of vegetable food stuffs grown in the fields around steel industries. Thirteen vegetable types including fruit vegetables, root vegetables, and leafy vegetables (LVs) along with soil samples were collected from agricultural fields around M-site (Mandi-Gobindgarh industrial site) and C-site (control non-industrial site) and analysed for Al on WD-XRF. Higher vegetable Al content was reported due to higher soil Al content and higher acidic soil pH at M-site than C-site. Correlation coefficient data have shown positive correlation of plant/vegetable Al with soil Al whereas negative correlation with soil pH at both the sites. Hierarchical cluster analysis based on vegetable Al content and bioaccumulation factor depicted higher number of clusters of vegetables at M-site (3-clusters) than C-site (2-clusters). The hazard quotients for Al intake in children and adults were found less than one. However, the weekly dietary Al exposure data have shown more than provisional tolerable weekly intake of 2 mg/kgbw/week in them from two LVs (Spinach and Brassica) from M-site than C-site which increases health concerns in humans from Mandi-Gobindgarh.

据报道，由于工业中的酸雨导致土壤铝含量增加和土壤酸化，冶金工业过程会通过植物食物的摄入而导致人类体内更多的铝（Al）暴露。曼迪-戈宾加尔（Mandi-Gobindgarh）是印度受到严重污染的钢铁工业城镇，其中的Al用于钢铁生产中的脱氧，晶粒细化和合金化。据报道，对铝的加工将铝释放到环境中，因此，本研究旨在调查在钢铁工业周围地区种植的蔬菜食品的消费对儿童和成人Mandi-Gobindgarh成年人的膳食铝暴露。十三种蔬菜，包括水果蔬菜，块根蔬菜，并从M站点（Mandi-Gobindgarh工业站点）和C站点（非工业控制站点）附近的农田中收集了叶类蔬菜（LVs）以及土壤样品，并在WD-XRF上分析了Al。据报道，蔬菜中的铝含量较高，这是由于M部位的土壤Al含量和酸性土壤pH值均高于C部位。相关系数数据表明，两个地点的植物/植物铝与土壤铝呈正相关，而与土壤pH呈负相关。基于蔬菜中铝含量和生物积累因子的层次聚类分析表明，M地点（3集群）的蔬菜集群数量高于C地点（2集群）的蔬菜集群数量。发现儿童和成人摄入铝的危险商少于一。然而，
