城市街道灰尘(UStD)是人类健康的重要问题,对城市可持续发展至关重要。这项研究旨在加强创造安全,负担得起的,通过检查城市居住区的环境污染和健康风险,以及具有弹性的城市。具体来说,它研究了铬(Cr)的浓度和空间分布,镉(Cd),镍(Ni),铜(Cu),铅(Pb),Yenimahalle的UStD中的锌(Zn),安卡拉.锌的平均浓度,Cr,Pb,Cd,Ni,UStD中的Cu分别为97.98、66.88、55.22、52.45、38.37和3.81mg/kg,分别。这些元素的地质累积污染指数(Igeo)值为:Cd(5.12),Ni(1.61),Cr(1.21),Pb(1.13),Cu(0.78),锌(0.24)。这些指数表明该地区受到Cr的中度污染,Pb,Ni,未被铜和锌污染至中度污染,并被Cd污染严重。Cr的危险指数(HI)值,Cd,Ni,Cu,Pb,锌低于成人的非致癌风险阈值,表明没有重大风险。然而,对于孩子们来说,Pb的HI值,Ni,Cd,和Zn分别为3.37、1.80、1.25和1.25,暗示了更高的风险。Cd的致癌风险(RI),Ni,铅对儿童和成人都很重要,表明通过摄入暴露,吸入,皮肤接触是危险的。调查结果强调了对自然和人为活动采取战略缓解措施的必要性,为居民提供必要的见解,政策制定者,利益相关者,城市规划者。
Urban street dust (UStD) is a vital issue for human health and is crucial for urban sustainability. This study aims to enhance the creation of safe, affordable, and resilient cities by examining environmental contamination and health risks in urban residential areas. Specifically, it investigates the concentrations and spatial distribution of chromium (Cr), cadmium (Cd), nickel (Ni), copper (Cu), lead (Pb), and zinc (Zn) in UStD in Yenimahalle, Ankara. The mean concentrations of Zn, Cr, Pb, Cd, Ni, and Cu in UStD were 97.98, 66.88, 55.22, 52.45, 38.37, and 3.81 mg/kg, respectively. The geoaccumulation pollution index (Igeo) values for these elements were: Cd (5.12), Ni (1.61), Cr (1.21), Pb (1.13), Cu (0.78), and Zn (0.24). These indices indicate that the area is moderately polluted with Cr, Pb, and Ni, uncontaminated to moderately contaminated with Cu and Zn, and extremely polluted with Cd. The hazard index (HI) values for Cr, Cd, Ni, Cu, Pb, and Zn were below the non-carcinogenic risk threshold for adults, indicating no significant risk. However, for children, the HI values for Pb, Ni, Cd, and Zn were 3.37, 1.80, 1.25, and 1.25, respectively, suggesting a higher risk. Carcinogenic risk (RI) of Cd, Ni, and Pb was significant for both children and adults, indicating that exposure through ingestion, inhalation, and dermal contact is hazardous. The findings highlight the need for strategic mitigation measures for both natural and anthropogenic activities, providing essential insights for residents, policymakers, stakeholders, and urban planners.
