Essential, toxic and potentially toxic elements in White Storks' blood

This dataset contains trace element concentration data measured in whole blood samples from 189 live white storks (Ciconia ciconia) captured in central Spain. Sampling took place across several municipalities in the Madrid region as part of a biomonitoring program aimed at assessing environmental contamination in avian wildlife.

Each row corresponds to an individual bird and includes biological and health-related information such as age (chick or adult), body condition, and the presence or absence of trauma or foreign bodies. A total of 52 chemical elements were quantified using inductively coupled plasma mass spectrometry (ICP-MS), covering both essential (e.g., Fe, Zn, Cu, Se) and non-essential or toxic elements (e.g., Pb, Cd, Hg, As), along with several rare earth and trace elements. Results are expressed in nanograms per milliliter (ng/mL), equivalent to micrograms per liter (µg/L), based on wet weight concentrations in whole blood.

Variables in the dataset include:

Reference: unique sample identifier

Species: white stork (Ciconia ciconia)

Municipality: location of capture

Age: classified as chick or adult

Body condition: qualitative status (e.g., average, thin)

Health indicators: including trauma and foreign body presence

Elemental concentrations: 52 variables in ng/mL for a wide panel of trace elements

This dataset offers a unique insight into the internal exposure of free-ranging storks to environmental pollutants in urban and peri-urban settings. It may serve as a reference for ecotoxicological studies, risk assessment, and conservation strategies focused on large avian species in human-dominated landscapes.

本数据集包含189只活体白鹳（Ciconia ciconia）的全血样品微量元素浓度数据，这些白鹳捕获于西班牙中部地区。采样工作在马德里大区的多个市镇开展，作为野生禽类环境污染生物监测项目的一部分，旨在评估野生禽类的环境污染状况。

每一行对应一只个体白鹳，包含其生物学与健康相关信息，包括年龄（雏鸟或成鸟）、体况，以及是否存在创伤或异物。本次研究采用电感耦合等离子体质谱法（inductively coupled plasma mass spectrometry, ICP-MS）对共计52种化学元素进行定量分析，涵盖必需元素（如铁Fe、锌Zn、铜Cu、硒Se）、非必需或有毒元素（如铅Pb、镉Cd、汞Hg、砷As），以及多种稀土元素与微量元素。检测结果以全血湿重计，单位为纳克每毫升（ng/mL），等同于微克每升（µg/L）。

本数据集包含的变量如下：
- 参考编号：唯一样本标识符
- 物种：白鹳（Ciconia ciconia）
- 捕获市镇：捕获地点所属市镇
- 年龄：分为雏鸟或成鸟两类
- 体况：定性评估状态（如中等、瘦弱）
- 健康指标：包括创伤与异物存在情况
- 元素浓度：52项以ng/mL为单位的广谱微量元素浓度变量

本数据集为了解野外自由活动的白鹳在城市及城郊环境中的体内暴露水平提供了独特视角，可作为生态毒理学研究、风险评估，以及针对人类活动主导景观中大型禽类物种的保护策略的参考依据。
