摘要
目的了解2020年济南市大气PM_(2.5)中元素的浓度特征,评估其健康风险。方法于2020年每月7d在济南市两区(市中区和历城区)分别设置大气PM_(2.5)采样点,分析11种元素的浓度特征。采用《化学物质环境健康风险评估技术指南》的方法计算元素的慢性健康风险。结果2020年11种元素中,铝、锰、铅3种成分浓度较高,合计占90%以上。铬、砷、镉致癌风险中位数均超过1.0×10^(-6);锰有10.84%(市中区)和19.28%(历城区)非致癌风险超过1.0,砷有3.61%(市中区)的非致癌风险超过1.0。结论2020年济南市大气PM_(2.5)中铬、砷、镉、锰的浓度及慢性健康风险仍较高,建议在今后的大气污染溯源中进一步加强对非交通源的识别与控制。
Objectives To support the local air control and management,we described the concentration characters of the Jinan's atmospheric fine particulate matter fine particulate matter(PM_(2.5))related mental elements and estimated the chronic health risk during 2020.Methods Two air sample-settings of atmospheric PM_(2.5)was set in Shizhong district(central-urban-area)and Licheng district(urban-rural-area)of Jinan.PM_(2.5)-related mental elements component quartz filter samples were collected 7 days from 10 to 16 each month in 2020.11 metal components were tested,including antimony,aluminum,arsenic,beryllium,cadmium,chromium,lead,mercury,manganese,nickel and selenium.Technical Guide for Environmental Health Risk Assessment of Chemical Substances was used to estimate the chronic health risks of the PM_(2.5)-related 11 mental elements,including carcinogenic risk(Risk)and Hazard quotient(HQ).Results Total of 154 air samples was collected during the study period.In PM_(2.5)-related 11 mental elements,Al,Mn and Pb get the high concentration and account for over 90%proportion in total.Among the carcinogenic risks,Cr,As and Cd were identified as a higher carcinogenic risk of over than 1.0×10^(-6).Among the Hazard quotient,10.84%of Mn and 3.61%of As exceeded 1.0 in central-urban-area,and 19.28%of Mn exceeded 1.0 in urban-rural-area.Conclusions High chronic health risks of PM_(2.5)-related chromium,arsenic,cadmium and manganese was observed in Jinan of 2020.More concern need to be pay in the future air pollution traceability control,and in the sources identification not only for the transportation but also for other emission.
