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.

本数据集共计收录1158条记录，涵盖针对每名个体并行测定的关键变量，包括性别、年龄以及尿液与血液中的砷浓度水平。本数据集可支持针对多样化人群的砷暴露情况开展深入分析，支持基于性别与年龄的分层研究，以及尿液与血液砷浓度的对比分析。该数据集可为砷毒性研究、人群级暴露评估以及潜在生物标志物识别相关工作提供支撑，同时可为统计分析、基于CRN值的标准化处理，以及尿液生物标志物校正公式的验证提供极具价值的研究资源。
