北京、上海、广州、西安和武汉五城市人群历史暴露参数数据

原始数据采样地点主要于北京、上海、广州、西安和武汉，使用问卷调查的方式，主要数据采集时间为2011年。数据由北京科技大学采集并分析，按城市、性别、年龄进行分类处理，经质量控制、异常值剔除形成数据集。暴露参数包括：身高、体重、室内外活动时间、不同体力活动的时间、不同交通工具使用时间等。暴露参数数据可用于大气颗粒物组分健康风险评估，探究大气颗粒物组分暴露对人群的致癌风险和非致癌风险，从而为污染源管控提供依据；另外，可以用于计算大气污染物长期暴露对人群健康风险大的影响，为人群防护提供建议。

The original data were mainly collected in Beijing, Shanghai, Guangzhou, Xi’an and Wuhan through questionnaire surveys, with the primary data collection occurring in 2011. The data were collected and analyzed by the University of Science and Technology Beijing, and were categorized by city, gender and age. The final dataset was established after quality control and outlier elimination. Exposure parameters include height, weight, indoor and outdoor activity durations, durations of different types of physical activities, and durations of using various transportation modes, among others. The exposure parameter data can be applied to conduct health risk assessments of atmospheric particulate matter components, to investigate the carcinogenic and non-carcinogenic risks of population exposure to atmospheric particulate matter components, thus providing a scientific basis for pollution source control. Additionally, the data can be used to calculate the impacts of long-term exposure to atmospheric pollutants on population health risks, and offer recommendations for population protection.
