Present study was chosen to elucidate the role of Environmental Pollution in the contamination of vegetables with trace elements in Mandi-gobindgarh (India) and associated potential risk to human health. Total 14 vegetable types including leafy vegetables (Brassica, Metha, Coriander, Spinach, Cabbage), fruit vegetables (Brinjal, Cauliflower, Bottle-gourd, Tomato, Green chilli) and root vegetables (Radish, Carrot, Turnip, Potato) were collected from Mandi-gobindgarh and analyzed for Zn, Cu, Mn, Mo, Ni, Se and Fe on WD-XRF. Results showed more than permissible limits of Zn (23.60-137.60 mg/kg), Cu (20.30-251.60 mg/kg), Mo (5.50-213.60 mg/kg), Se (8.33-11.20 mg/kg) and Fe (21.60-452.70 mg/kg) whereas lower contents of Mn (10.70-112.30 mg/kg) and Ni (6.50-12.00 mg/kg) in the vegetables. Daily intakes calculated for Zn, Mn, Ni and Fe in children and adults were less than their RDA/AI/UL (except Mn and Fe in leafy vegetables). However, daily intakes of Cu, Mo and Se were found higher than their RDA except Cu in few vegetables. Hazard quotients (HQs) calculated in children and adults were more than 1 (HQ > 1) for Cu, Mo and Se whereas less than 1 (HQ < 1) for Zn, Mn, Ni and Fe. Hazard Index (HI) in children and adults was observed more than one in 11 vegetable types with maximum contamination in Tomato and minimum in Coriander except Radish and Carrot (uncontaminated vegetables). It was concluded that Environmental Pollution in Mandi-gobindgarh has increased the metal contents of Zn, Cu, Mo, Se and Fe in the vegetables but health risks in children and adults were evaluated due to higher Cu, Mo and Se contents in the vegetables.
本研究旨在阐明环境污染在曼迪戈宾德加尔(印度)蔬菜中痕量元素污染中的作用,以及对人类健康的潜在风险。共采集了 14 种蔬菜,包括叶菜类(甘蓝、生菜、香菜、菠菜、白菜)、果菜类(茄子、菜花、葫芦、番茄、青椒)和根菜类(萝卜、胡萝卜、芜菁、土豆),采用 WD-XRF 对蔬菜中的 Zn、Cu、Mn、Mo、Ni、Se 和 Fe 进行分析。结果表明,蔬菜中 Zn(23.60-137.60mg/kg)、Cu(20.30-251.60mg/kg)、Mo(5.50-213.60mg/kg)、Se(8.33-11.20mg/kg)和 Fe(21.60-452.70mg/kg)的含量超过了允许限量,而 Mn(10.70-112.30mg/kg)和 Ni(6.50-12.00mg/kg)的含量较低。计算出儿童和成人对 Zn、Mn、Ni 和 Fe 的日摄入量低于其 RDA/AI/UL(叶菜类中的 Mn 和 Fe 除外)。然而,除了少数几种蔬菜中的 Cu 外,Mo 和 Se 的日摄入量均高于其 RDA。儿童和成人的危害系数(HQ)均大于 1(HQ>1),表明 Cu、Mo 和 Se 存在危害,而 Zn、Mn、Ni 和 Fe 的 HQ 小于 1(HQ<1)。在 11 种蔬菜中,儿童和成人的健康指数(HI)均超过 1,其中番茄污染最严重,香菜污染最小,除了萝卜和胡萝卜(无污染蔬菜)。研究结果表明,曼迪戈宾德加尔的环境污染增加了蔬菜中 Zn、Cu、Mo、Se 和 Fe 的含量,但由于蔬菜中 Cu、Mo 和 Se 的含量较高,对儿童和成人的健康风险进行了评估。
