基于人群的研究估计了使用PM2.5的质量（空气直径≤2.5μm）作为质量颗粒的健康风险。有限。
在这项研究中，我们调查了美国心血管疾病（CVD）的住院与呼吸道疾病的关联与美国PM2.5的化学成分之间的关联。
我们使用了一个国家数据库，该数据库完成了2000 - 2006年的每日数据，涉及心血管和呼吸结果的紧急医院入院，主要PM2.5化学成分的环境水平[硫酸盐，硝酸盐，硝酸盐，硅，元素，元素碳（EC），有机碳质（OCM），有机碳质（OCM） ，钠和铵离子]，以及使用贝叶斯分层统计模型的天气在119个美国城市社区的医院入院（≥65岁）。
在调整其他污染物水平的多种污染物模型中，EC的四分位间范围（IQR）增加与0.80％[95％的后间隔（PI），0.34–1.27％]同日增加的风险增加心血管入院和OCM的IQR增加与1.01％（95％PI，0.04-1.98％）相关，同一天的呼吸道风险增加。与多种污染物模型中的心血管或呼吸道医院入院有关。
由车辆排放，柴油和木材燃烧产生的EC和OCM的环境水平与PM2.5的主要化学构成中最大的紧急住院治疗风险有关。
Population-based studies have estimated health risks of short-term exposure to fine particles using mass of PM2.5 (particulate matter ≤ 2.5 μm in aerodynamic diameter) as the indicator. Evidence regarding the toxicity of the chemical components of the PM2.5 mixture is limited. In this study we investigated the association between hospital admission for cardiovascular disease (CVD) and respiratory disease and the chemical components of PM2.5 in the United States. We used a national database comprising daily data for 2000–2006 on emergency hospital admissions for cardiovascular and respiratory outcomes, ambient levels of major PM2.5 chemical components [sulfate, nitrate, silicon, elemental carbon (EC), organic carbon matter (OCM), and sodium and ammonium ions], and weather. Using Bayesian hierarchical statistical models, we estimated the associations between daily levels of PM2.5 components and risk of hospital admissions in 119 U.S. urban communities for 12 million Medicare enrollees (≥ 65 years of age). In multiple-pollutant models that adjust for the levels of other pollutants, an interquartile range (IQR) increase in EC was associated with a 0.80% [95% posterior interval (PI), 0.34–1.27%] increase in risk of same-day cardiovascular admissions, and an IQR increase in OCM was associated with a 1.01% (95% PI, 0.04–1.98%) increase in risk of respiratory admissions on the same day. Other components were not associated with cardiovascular or respiratory hospital admissions in multiple-pollutant models. Ambient levels of EC and OCM, which are generated primarily from vehicle emissions, diesel, and wood burning, were associated with the largest risks of emergency hospitalization across the major chemical constituents of PM2.5.
