项目摘要
The broad aim of this research is to develop an occupational exposure monitoring and control strategy, based on time-activity data for specific tasks, to constrain exposures to acceptable levels and minimize reliance on invasive biological measurements. Recently an intervention program developed to eliminate high blood lead levels in Connecticut bridge construction workers was shown to be effective. (Vork et. al., submitted) (Appendix A). This intervention program used contract specifications to require the lead health protection program and paid the expenses incurred by contractors to ensure that it would be successfully implemented. Among many strategies, frequent blood lead monitoring was required. These tests were used to alert employers and sometimes require them to reduce future exposures to airborne lead in specific workers. In addition to blood lead monitoring, the lead health protection program also required comprehensive industrial hygiene monitoring. The data collected during both the blood lead and the industrial hygiene monitoring programs provide the detailed information required for this research goal to be pursued in the context of lead exposure in bridge rehabilitation work. This research proposes to: use the blood lead data and time- activity patterns from the cohort involved in the Connecticut intervention program to estimate recent lead exposure (i.e. the cumulative lead intake from work over the past 30 day period); to use the Categorization and Regression Tree (CART) analysis of one half of the Connecticut cohort to determine the predictive value of various task, personal and environmental variables on cumulative lead intake as estimated in specific aim one; to validate the regression model derived in Specific Aim 2 using the other half of the data from the Connecticut intervention program cohort; and explore the implications of the regression model for identifying: a) cost-effective surveillance requirements for ongoing exposure control programs including the potential deficiencies in the Connecticut data set: and b) efficacious control strategies
这项研究的主要目的是根据特定任务的时间-活动数据,制定职业暴露监测和控制战略,将暴露限制在可接受的水平,并最大限度地减少对侵入性生物测量的依赖。最近,一项旨在消除康涅狄格州桥梁建筑工人高血铅水平的干预计划被证明是有效的。沃克等人已提交)(附录A)。这项干预计划使用合同规范要求牵头健康保护计划,并支付承包商发生的费用,以确保其成功实施。在许多策略中,需要经常监测血铅。这些测试被用来提醒雇主,有时还要求他们减少未来对特定工人空气中铅的暴露。除了血铅监测外,铅健康保护计划还需要全面的工业卫生监测。在血铅和工业卫生监测计划期间收集的数据提供了在桥梁修复工作中铅暴露的背景下实现这一研究目标所需的详细信息。这项研究建议:使用康涅狄格州干预计划队列中的血铅数据和时间-活动模式来估计最近的铅暴露(即过去30天期间从工作中累积的铅摄入量);使用分类和回归树(CART)分析康涅狄格州队列中一半的人来确定各种任务、个人和环境变量对特定目标一中估计的累积铅摄入量的预测值;使用来自康涅狄格州干预计划队列的另一半数据来验证在特定目标2中得出的回归模型;并探索回归模型的含义,以确定:a)正在进行的暴露控制方案的成本效益监测要求,包括康涅狄格州数据集的潜在缺陷:和b)有效的控制战略
