研究目的: |
1.本研究拟构建臭氧暴露染毒舱系统,采用随机对照设计,揭示臭氧急性暴露的潜在健康风险,为制定空气质量标准与人群防护策略提供依据; 2.识别臭氧暴露对于cfDNA片段大小,甲基化水平等特征的影响,并探索其特征变化的毒理学意义,评估其表征臭氧健康损害效应的可行性。 |

|
Objectives of Study: |
1. This study aims to develop an ozone exposure chamber system and employs a randomized controlled design to elucidate potential health risks from acute ozone exposure, providing evidence for establishing air quality standards and population protection strategies. 2. The research will identify ozone-induced alterations in cfDNA characteristics including fragment size and methylation levels, investigate the toxicological significance of these changes, and evaluate the feasibility of utilizing cfDNA features to characterize ozone-related health damage. |
