建筑工地将工人暴露在高颗粒物 (PM) 的环境中. 这项研究量化了PM排放量,并确定了高风险的工作,使用DALY来评估健康影响和告知控制策略.
科学领域:
- 环境科学 环境科学
- 职业健康 职业健康 职业健康
- 建筑工程工程 建筑工程
背景情况:
- 建筑颗粒物 (PM) 由于意识和控制措施不足,对工人造成重大环境和健康风险.
- 建筑工地是复杂的环境,具有动态的PM来源和扩散模式,需要对暴露和健康影响进行定量评估.
- 现有的PM度控制系统缺乏有效的现场环境管理所需的技术和数据支持.
研究的目的:
- 测量和计算不同施工阶段和运营区域的颗粒物排放因子.
- 模拟建筑工地PM度的时间和空间分布.
- 评估建筑工人暴露于PM的职业健康风险,并使用DALYs将这些风险货币化.
主要方法:
- 现场测量了上海三个建筑工地总悬浮颗粒物 (TSP),PM10和PM2.5质量度.
- 计算不同建筑阶段的颗粒物排放因子 (基础,主结构,安装/装饰).
- 使用专用软件模拟颗粒度分布,使用残疾调整寿命年 (DALYs) 评估健康风险.
主要成果:
- 根据基础,主结构和安装/装饰阶段,确定了TSP,PM10和PM2.5的排放因子.
- 模拟确定了高风险职业:坑底工人 (基础),钢铁条加工工人 (主要结构) 和石膏/石匠/工人 (安装/装饰).
- DALYs被用来量化建筑工人暴露于PM所带来的健康风险.
结论:
- 该研究提供了关键的关于建筑工地PM排放和暴露风险的定量数据.
- 这些发现支持基于证据的决策,以实施有效的PM控制策略.
- 通过针对特定的高风险活动和工人群体的有针对性的干预措施,可以实现改善建筑工地职业健康管理.
