The goals of the present research were to determine the heavy metal contents in the water-soil-cauliflower samples in industrial wastewater irrigated areas and to assess the health risks of these metals to the people. Metal analyses were carried out using the atomic absorption spectrophotometer equipped with a graphite furnace. The metal readings in the cauliflower specimens ranged from 1.153 to 1.389, 0.037 to 0.095, 0.61 to 0.892, 0.625 to 0.921, 1.165 to 2.399, 0.561 to 0.652, 0.565 to 0.585, 0.159 to 0.218 and 1.268 to 1.816 mg/kg for Cd, Co, Cr, Cu, Fe, Ni, Pb, Zn and Mn, respectively. Statistics revealed that, with the exception of Pb and Co (p > 0.05), there was no statistically significant variation in the metal concentrations in the cauliflower samples according to the irrigation type. Pb, Ni, and Cr had HRI values below 1.0 and did not seem to be a hazard to human health, in contrast to Cd, Co, Cr, Cu, Fe, Ni, Pb, Zn and Mn, which glanced to constitute a health risk. Regular monitoring of vegetables irrigated with wastewater is strongly advised to reduce health hazards to people.
本研究的目的是测定工业废水灌溉区水土-花椰菜样品中的重金属含量，并评估这些金属对人体的健康风险。金属分析采用配备石墨炉的原子吸收分光光度计进行。花椰菜样本中的金属读数范围为 1.153 至 1.389、0.037 至 0.095、0.61 至 0.892、0.625 至 0.921、1.165 至 2.399、0.561 至 0.652、0.565 至 0.585、0.159 至 0.218 和 1.268 至 1.816mg/kg，分别为 Cd、Co、Cr、Cu、Fe、Ni、Pb、Zn 和 Mn。统计数据显示，除 Pb 和 Co（p>0.05）外，根据灌溉类型，花椰菜样本中的金属浓度没有统计学上的显著差异。与 Cd、Co、Cr、Cu、Fe、Ni、Pb、Zn 和 Mn 相比，Pb、Ni 和 Cr 的 HRI 值低于 1.0，似乎不会对人体健康构成危害，而后者则被认为构成了健康风险。强烈建议对用废水灌溉的蔬菜进行定期监测，以降低对人体的健康危害。
