背景：据报道，绿色空间可改善健康状况，包括对妊娠结局的有益影响。尽管有人建议绿色空间与空气污染有关的健康益处，但没有证据表明绿色对个人暴露于空气污染的影响。目的：我们调查了孕妇周围的绿色和个人暴露于空气污染之间的关系，并探讨了这种关系背后的潜在机制。方法：在2008-2009年期间，对居住在巴塞罗那的54名孕妇进行了65轮抽样。每轮包括2天的空气动力学直径≤ 2.5 μm的颗粒物（PM2.5）测量和1周的氮氧化物测量，同时收集个人和微环境水平。研究参与者还被要求在采样期间填写时间-微环境-活动日记。我们使用卫星检索，以确定周围的绿化的平均归一化差异植被指数（NDVI）在缓冲区的100米左右的每个产妇居住地址。我们估计了环境绿化对个人暴露水平、家庭-室外和家庭-室内污染物水平以及母亲时间-活动的影响。结果如下：较高的住宅周围绿化与较低的个人，家庭室内和家庭室外PM2.5水平，以及更多的时间花在家庭室外。结论：我们发现居住在绿色地区的孕妇个人暴露于空气污染的水平较低。这一发现的部分原因可能是较低的家庭室内污染物水平和更多的时间花在污染较少的家庭室外环境中的孕妇在绿色地区。
Background: Green spaces are reported to improve health status, including beneficial effects on pregnancy outcomes. Despite the suggestions of air pollution–related health benefits of green spaces, there is no available evidence on the impact of greenness on personal exposure to air pollution. Objectives: We investigated the association between surrounding greenness and personal exposure to air pollution among pregnant women and to explore the potential mechanisms, if any, behind this association. Methods: In total, 65 rounds of sampling were carried out for 54 pregnant women who resided in Barcelona during 2008–2009. Each round consisted of a 2-day measurement of particulate matter with aerodynamic diameter ≤ 2.5 μm (PM2.5) and a 1-week measurement of nitric oxides collected simultaneously at both the personal and microenvironmental levels. The study participants were also asked to fill out a time–microenvironment–activity diary during the sampling period. We used satellite retrievals to determine the surrounding greenness as the average of Normalized Difference Vegetation Index (NDVI) in a buffer of 100 m around each maternal residential address. We estimated the impact of surrounding greenness on personal exposure levels, home-outdoor and home-indoor pollutant levels, and maternal time-activity. Results: Higher residential surrounding greenness was associated with lower personal, home-indoor, and home-outdoor PM2.5 levels, and more time spent at home-outdoor. Conclusions: We found lower levels of personal exposure to air pollution among pregnant women residing in greener areas. This finding may be partly explained by lower home-indoor pollutant levels and more time spent in less polluted home-outdoor environment by pregnant women in greener areas.
