Soil Heavy Metal Concentration Dataset from Debrecen (2022) Based on Laboratory X-Ray Fluorescence Measurements

This dataset presents the results of a systematic survey of heavy metal concentrations in urban surface soils across Debrecen, Hungary, conducted in 2022. A total of 295 topsoil samples were collected during summer and autumn from various residential, industrial, and traffic-dense areas to capture the spatial variability of contamination. Laboratory analyses were performed using a Skyray Instrument Explorer 9000 X-Ray Fluorescence (XRF) spectrometer, yielding concentrations for eight heavy metals: arsenic (As), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb), and zinc (Zn). The dataset includes elemental concentrations, sample coordinates, and basic metadata. It provides a baseline reference for soil quality prior to anticipated industrial expansion in the region and supports environmental monitoring, risk assessment, and urban planning. Researchers in geochemistry, environmental engineering, urban ecology, and soil science may find this dataset valuable for comparative studies or modeling purposes.本数据集呈现了2022年针对匈牙利德布勒森市城区表层土壤重金属浓度开展的系统性调查结果。研究于夏季与秋季期间，从各类住宅、工业及交通密集区域共采集295件表层土壤样本，以完整刻画污染的空间变异性特征。本次实验室分析采用Skyray Instrument Explorer 9000型X射线荧光光谱仪（X-Ray Fluorescence, XRF）完成，共获取8种重金属的浓度数据，分别为砷（As）、镉（Cd）、钴（Co）、铬（Cr）、铜（Cu）、镍（Ni）、铅（Pb）及锌（Zn）。本数据集包含元素浓度、样本坐标及基础元数据。该数据集可为该区域预期工业扩张前的土壤质量提供基准参照，并可为环境监测、风险评估及城市规划提供数据支撑。地球化学、环境工程、城市生态学及土壤科学领域的研究人员可将本数据集用于对比研究或建模相关工作，具备较高科研价值。
