The 2009 Toxicology and Risk Assessment Conference (TRAC) session on "Advances in Exposure and Toxicity Assessment of Particulate Matter" was held in April 2009 in West Chester, OH. The goal of this session was to bring together toxicology, geology and risk assessment experts from the Department of Defense and academia to examine issues in exposure assessment and report on recent epidemiological findings of health effects associated with particulate matter (PM) exposure. Important aspects of PM exposure research are to detect and monitor low levels of PM with various chemical compositions and to assess the health risks associated with these exposures. As part of the overall theme, some presenters discussed collection methods for sand and dust from Iraqi and Afghanistan regions, health issues among deployed personnel, and future directions for risk assessment research among these populations. The remaining speakers focused on the toxicity of ultrafine PM and the characterization of aerosols generated during ballistic impacts of tungsten heavy alloys.
2009 年毒理学和风险评估会议（TRAC）关于“颗粒物暴露和毒性评估的进展”的会议于 2009 年 4 月在俄亥俄州的西切斯特举行。本次会议的目的是汇集来自国防部和学术界的毒理学、地质学和风险评估专家，共同探讨暴露评估方面的问题，并报告与颗粒物（PM）暴露相关的最新流行病学健康效应发现。PM 暴露研究的重要方面是检测和监测具有各种化学成分的低水平 PM，并评估与这些暴露相关的健康风险。作为整体主题的一部分，一些演讲者讨论了从伊拉克和阿富汗地区采集沙和尘的方法、部署人员的健康问题以及这些人群的风险评估研究的未来方向。其余演讲者重点介绍了超细 PM 的毒性以及钨重合金弹道冲击产生的气溶胶的特性。
