我们根据文献创建了建筑行业中可吸入结晶二氧化硅水平的暴露数据库。我们提取了 1990 年或之后出版的报告二氧化硅暴露水平或控制有效性定量评估的出版物中的二氧化硅和灰尘暴露水平。该数据库包含从 115 个来源提取的 6118 条记录（2858 条可吸入结晶二氧化硅），总结了 11,845 项测量结果。四百八十八条记录代表汇总的暴露水平而不是单个值。对于这些记录，报告的汇总参数被标准化为几何平均值和几何标准差。每条记录与 80 个特征相关联，包括贸易、任务、材料、工具、采样策略、分析方法和控制措施等信息。尽管数据库是用法语构建的，但 38 个基本变量已标准化并翻译成英语。数据跨度为19742009年，其中92%的记录对应于个人测量。 13 个标准化行业和 25 个不同的标准化任务与至少 5 个单独的二氧化硅测量相关。特定行业的可吸入结晶二氧化硅几何平均值从 0.01（管道工）到 0.30mg/m3（隧道施工熟练工人）不等，而任务则从 0.01（六类，包括打磨和电气维护）到 1.59mg/m3（喷砂）不等。尽管文献数据的使用存在局限性，但该数据库可以使用荟萃分析和多元技术进行分析，并且目前代表了建筑行业二氧化硅暴露的最重要的暴露信息来源。它可以根据研究界的要求提供。 [本文提供了补充材料。请访问出版商的职业和环境卫生杂志在线版，获取以下免费补充资源：包含数据源列表和每个参数详细描述的附录。]
We created an exposure database of respirable crystalline silica levels in the construction industry from the literature. We extracted silica and dust exposure levels in publications reporting silica exposure levels or quantitative evaluations of control effectiveness published in or after 1990. The database contains 6118 records (2858 of respirable crystalline silica) extracted from 115 sources, summarizing 11,845 measurements. Four hundred and eighty-eight records represent summarized exposure levels instead of individual values. For these records, the reported summary parameters were standardized into a geometric mean and a geometric standard deviation. Each record is associated with 80 characteristics, including information on trade, task, materials, tools, sampling strategy, analytical methods, and control measures. Although the database was constructed in French, 38 essential variables were standardized and translated into English. The data span the period 19742009, with 92% of the records corresponding to personal measurements. Thirteen standardized trades and 25 different standardized tasks are associated with at least five individual silica measurements. Trade-specific respirable crystalline silica geometric means vary from 0.01 (plumber) to 0.30mg/m3 (tunnel construction skilled labor), while tasks vary from 0.01 (six categories, including sanding and electrical maintenance) to 1.59mg/m3 (abrasive blasting). Despite limitations associated with the use of literature data, this database can be analyzed using meta-analytical and multivariate techniques and currently represents the most important source of exposure information about silica exposure in the construction industry. It is available on request to the research community. [Supplementary materials are available for this article.
