PROJECT SUMMARY People are exposed to Polycyclic Aromatic Hydrocarbons (PAHs) regularly. PAHs are ubiquitous in our environments, and long-term exposure can lead to many adverse health diseases, including cognitive and neural development delay in infants (prenatal exposure), atherosclerosis, liver problems and cancer. Developing a simple instrument capable of providing semi-continuous levels of ambient PAH will fill the gap of temporal variability data in exposure assessment studies and could provide accurate information to increase our understanding of the effect of PAHs in adverse health outcomes.

项目概要 人们经常接触多环芳烃 (PAH)。 PAHs在我们的生活中无处不在 环境和长期接触会导致许多不良健康疾病，包括认知和疾病 婴儿神经发育迟缓（产前暴露）、动脉粥样硬化、肝脏问题和癌症。 开发一种能够提供半连续环境 PAH 水平的简单仪器将填补以下空白： 暴露评估研究中的时间变异性数据可以提供准确的信息以增加 我们对多环芳烃对不良健康结果影响的了解。
