目标
我们研究了旨在减少住宅木材燃烧的规则4901对圣华金谷空气盆地（SJVAB）颗粒物水平和住院率的影响。
方法
使用一般线性混合模型和广义估计方程模型，我们比较了SJVAB实施前（2000-2003）和实施后（2003-2006）烧伤季节期间心血管疾病（CVD）、缺血性心脏病（IHD）和慢性阻塞性肺疾病的颗粒物水平和住院人数（年龄组= 45-64岁和≥ 65岁）。
结果
实施后，我们观察到，在整个SJVAB以及空气盆地的农村和城市地区，直径2.5微米或更小的颗粒物（PM2.5）分别减少了12%，11%和15%，粗颗粒物减少了8%，7%和11%。在65岁及以上的人群中，在整个SJVAB以及农村和城市地区，估计规则4901分别预防了7%、8%和5%的CVD病例以及16%、17%和13%的IHD病例。
结论
该研究表明，规则4901可有效降低冬季环境PM2.5水平，并减少65岁及以上人群因心脏病住院的人数。
OBJECTIVES
We examined the impact of Rule 4901, aimed at reducing residential wood burning, on particulate matter levels and hospitalizations in the San Joaquin Valley Air Basin (SJVAB).
METHODS
Using general linear mixed models and generalized estimating equation models, we compared levels of particulate matter and of hospital admissions (age groups = 45-64 and ≥ 65 years) in the SJVAB for cardiovascular disease (CVD), ischemic heart disease (IHD), and chronic obstructive pulmonary disease during the burn seasons before (2000-2003) and after (2003-2006) implementation.
RESULTS
After implementation, we observed reductions of 12%, 11%, and 15% in particulate matter 2.5 micrometers in diameter or smaller (PM2.5), and 8%, 7%, and 11% in coarse particles, in the entire SJVAB and in rural and urban regions of the air basin, respectively. Among those aged 65 years and older, Rule 4901 was estimated to prevent 7%, 8%, and 5% of CVD cases, and 16%, 17%, and 13% of IHD cases, in the entire SJVAB and in rural and urban regions, respectively.
CONCLUSIONS
The study suggests that Rule 4901 is effective at reducing wintertime ambient PM2.5 levels and decreasing hospital admissions for heart disease among people aged 65 years and older.
