Dataset on spatial distribution of particulate matter-bound polycyclic aromatic hydrocarbons (PAHs) in roadside soils across urban zones with varying green space density and associated health risks in Sabzevar, Iran

This dataset contains raw concentrations of 15 priority polycyclic aromatic hydrocarbons (PAHs) measured in roadside soil samples collected from Sabzevar, Iran (n=20). PAHs were extracted using Soxhlet extraction and analyzed by GC-MS in SIM mode. Concentrations are expressed in ng/g dry soil. The dataset includes: Location code (0=control, 1=Tohid City, 2=Tehran Road, 3=Sarbedaran Square) Sampling distance code (3=nearest to road, 0=farthest, 50m from road) Individual PAH concentrations (DBA, IND, BaP, BbF, CRY, BaA, PYR, FLT, ANT, PHE, FLU, ACE, ACY, NA) Total PAHs (ΣPAHs), low molecular weight (ΣLMW-PAHs), and high molecular weight (ΣHMW-PAHs) The second sheet provides the legend for location and distance codes.本数据集收录了伊朗萨卜泽瓦尔（Sabzevar）地区采集的20份路边土壤样品中15种优先控制多环芳烃（polycyclic aromatic hydrocarbons, PAHs）的原始浓度数据。所有多环芳烃均采用索氏提取（Soxhlet extraction）法完成萃取，并通过气相色谱-质谱联用仪（GC-MS）的选择离子监测（SIM）模式进行分析，浓度以ng/g干土为单位表示。 本数据集包含以下内容： 1. 采样点位编码（0代表对照点，1为托伊德市，2为德黑兰路，3为萨贝达兰广场） 2. 采样距离编码（3代表距道路最近，0代表距道路最远，50m代表距道路50米处） 3. 各单体多环芳烃浓度（含DBA、IND、BaP、BbF、CRY、BaA、PYR、FLT、ANT、PHE、FLU、ACE、ACY、NA） 4. 总多环芳烃（ΣPAHs）、低分子量多环芳烃（ΣLMW-PAHs）与高分子量多环芳烃（ΣHMW-PAHs） 本数据集的第二个工作表包含采样点位与采样距离编码的说明。
