Abstract

Contamination of college campus dust with heavy metals and the calculation of their ecological and health risks to the students and staff did not receive much attention except in recent years. This study aims to assess the ecological and human health risks of Cd, Cr, Cu, Pb, and Zn in interior dust of College of Science/University campus. An atomic absorption spectrophotometer was utilized to estimate the samples that were collected from 46 locations of the college campus including: classrooms, offices, and laboratories. The Pb, Cu, Cr and Zn metals in the interior dust of the College of Science pose low potential ecological risk, whereas Cd generates medium potential ecological risk. The gained results showed that the student and staff of the College are exposed to low non-cancerous health risks (HI < 1) caused by Cd, Cr, Cu, Pb, and Zn in interior dust. The total lifetime carcinogenic risks (TLCR) of Cd, Cr, and Pb are within the acceptable safe limit (10^–6–10^–4). The low non-carcinogenic health risks of Cd, Cr, Cu, Pb, and Zn and that the carcinogenic health risks of Cd, Cr and Pb fall within acceptable safe limits, measured in the interior dust of the campus of the College of Science, does not mean neglecting the continuous assessment of those risks.

大学校园室内灰尘中重金属的生态和健康风险评估。

大学校园粉尘中的重金属污染及其对学生和教职员工的生态和健康风险的计算，除近几年外并未受到广泛关注。本研究旨在评估理学院/大学校园内部灰尘中的镉、铬、铜、铅和锌对生态和人类健康的风险。研究人员利用原子吸收分光光度计对从理学院校园内的教室、办公室和实验室等 46 个地点采集的样本进行了评估。理学院室内灰尘中的铅、铜、铬和锌对生态环境的潜在风险较低，而镉对生态环境的潜在风险中等。所得结果显示，理学院学生和教职员工暴露于低非致癌健康风险（HI -6-10-4）。在理学院校园内部灰尘中测得的镉、铬、铜、铅和锌的非致癌健康风险较低，镉、铬和铅的致癌健康风险在可接受的安全范围内，但这并不意味着忽视对这些风险的持续评估。
