目的对深圳和太原细颗粒物(particulate matter 2.5,PM_(2.5))进行金属元素分析和致癌风险评价。方法采集2017- 2018年深圳和太原PM_(2.5)样品,利用电感耦合等离子体质谱法(inductively coupled plasma mass spectrometry, ICP-MS)对PM_(2.5)中10种金属元素浓度进行测量,并采用美国环境保护署(U. S Environmental Protection Agency,EPA)推荐的人体健康风险评估模型评价其健康风险。结果2017- 2018年深圳PM_(2.5)中金属元素浓度排序:铝> 铅> 锰> 铬> 铜> 钒> 砷 > 镍> 镉> 钴,浓度分别是1 807.67、31.02、30.63、17.37、17.32、11.59、6.98、4.76、2.24和2.20 ng /m~3;太原2017- 2018年PM_(2.5)...

Objective To conduct metal elements analysis and risk assessment of carcinogenicity on Particulate Matter 2.5(PM_(2.5))collected from Shenzhen and Taiyuan. Methods PM_(2.5) samples were collected in Shenzhen and Taiyuan from 2017 to 2018. Ten heavy metal elements in PM_(2.5) samples were detected by inductively coupled plasma mass spectrometry(ICP-MS). Health risk assessment was conducted using the recommended United States Environmental Protection Agency(EPA)model. Results Metal elements found in PM_(2.5) samples from Shenzhen included(in decr...
