Arsenic Raw Data Set 2 - Urine - Blood

This dataset contains 1,158 records, including critical variables such as sex, age, and arsenic levels in urine and blood, measured in parallel for each individual. The dataset facilitates in-depth analysis of arsenic exposure across a diverse population, allowing for sex- and age-based stratifications and comparisons between urinary and blood arsenic concentrations. The dataset supports research into arsenic toxicity, population-level exposure assessment, and potential biomarker identification. It provides a valuable resource for statistical analysis, normalization using CRN values, and validation of urinary biomarker correction formulas.

本数据集共包含1158条记录，涵盖性别、年龄、尿液与血液砷水平等核心变量，所有变量均针对每名个体同步采集测定。本数据集可支持针对多样化人群的砷暴露水平开展深入分析，支持按性别与年龄进行分层研究，并可实现尿液与血液砷浓度的对比分析。本数据集可助力砷毒性、人群水平暴露评估以及潜在生物标志物识别相关研究。其可为统计分析、基于CRN值的归一化处理以及尿液生物标志物校正公式的验证提供宝贵的研究资源。
