| 2 | Multivariate statistical methods and GIS based evaluation of the health risk potential and water quality due to arsenic pollution in the Kızılırmak River显示文摘The Kızılırmak River is Turkey's longest(1,355 km)river and it is important since it constitutes the drinking and irrigation water source of the Central Anatolia Region.In the current study,the spatial distribution,effect on irrigation water quality,environmental pollution status,ecotoxicological and health risks as well as possible sources of 12 potential toxic elements'(PTEs)(manganese(Mn),aluminum(Al),arsenic(As),chromium(Cr),zinc(Zn),iron(Fe),nickel(Ni),cadmium(Cd),cobalt(Co),copper(Cu),mercury(Hg),and lead(Pb))concentrations from surface water samples in the Kızılırmak River were analyzed by using geographical information systems(GIS)software,ecotoxicological indices,and multivariate statistical analysis.As a result of the current study,it was determined that the As concentration is above the World Health Organization(WHO)limit values,and,in terms of the 12 PTEs,there is slight heavy metal contamination in the river according to the Heavy Metal Pollution Index(HPI)and Heavy Metal Evaluation Index(HEI)values and there is a low level of pollution.The Hazard Quotient for ingestion(HQingestion)and Hazard Index(HI)values indicate that non-carcinogenic effects may occur.Exposure to river water is likely to result in a low level of carcinogenic risk(CR)in adults,mainly due to the As concentration.The water at Sampling Station S3(131.79)cannot be used for drinking and is not suitable for consumption.According to the sodium percentage(Na%),Sodium Absorption Ratio(SAR),and Magnesium Hazard(MH)index results,river water is suitable for agricultural use. | Hüseyin Cüce Erkan Kalıpcı Fikret Ustaoglu Ilknur Kaynar Volkan Baser Mustafa Türkmen | 2022 | International Journal of Sediment Research2022，37，6： | 1 |
| 4 | 虹膜颜色与视网膜神经纤维层和黄斑及脉络膜厚度关系的研究(英文)显示文摘目的:明确眼虹膜颜色与眼轴长度、眼压、视网膜神经纤维层厚度(RNFL)、黄斑厚度、脉络膜厚度是否相关。方法:前瞻性横断面研究。92例(92眼)正常个体根据虹膜颜色分为深色组(DCE)和浅色组(LCE)。用标准光学相干断层扫描(OCT)分析RNFL和黄斑厚度,EDI(Electronic data interchange)分析脉络膜厚度。脉络膜厚度在中央凹及水平位置距离中央凹1500μm的鼻侧、颞侧进行测量。结果:92眼中,深色组62眼(67.4%)平均年龄29.22±5.86y,浅色组30眼(32.6%)平均年龄28.86±6.50y。各组间平均年龄、眼轴长度、黄斑厚度、脉络膜厚度及眼压无显著性差异(P>0.05)。视网膜神经纤维层厚度的变化取决于测量象限,而LCE个体在全眼球,鼻侧和颞侧象限较低(P≤0.022)。结论:深色组和浅色组个体间眼内压(IOP),黄斑厚度和脉络膜厚度无显著差异。 | Süleyman Demircan Ugur Yilmaz Yudum Yüce Ahmet Gülhan Erkut Kücük Mustafa Atas | 2017 | 国际眼科杂志2017，17，9： | 0 |
