与交通相关的空气污染物一直与有害的健康影响有关。我们假设，从1998年到2006年，由于政策干预，纽约市对多环芳烃(PAHs)、元素碳(EC，柴油指标)、颗粒物(PM2.5)和一系列金属的暴露有所下降。参与哥伦比亚儿童环境健康出生队列研究的孕妇个人监测的PAH水平，以及纽约州环境保护部五个固定监测仪的EC、PM2.5和金属数据，在不同地点和不同时间(1998-2006)进行了比较。单变量分析显示，从1998年到2006年，个人的多环芳烃暴露水平有所下降(p<；0.0001)。在控制了环境烟草烟雾、室内高温和烹饪后，个人监测年份仍然是Σ8PAHs下降的预测因素(β=−0.269，p<；0.001)。线性趋势分析还表明PM2.5有所下降(p=0.09)。固定点监测仪测量的EC和大多数金属的浓度，如方差分析所测量的，没有下降。在固定地点，空气中的EC和金属水平差异很大。相比之下，PM2.5水平高度相关(数值范围从0.725到0.922，p<；0.01)。为了对公众健康产生更大的影响，可能需要针对与交通相关的空气污染物的进一步政策举措。
Traffic-related air pollutants have been associated with adverse health effects. We hypothesized that exposure to polycyclic aromatic hydrocarbons (PAHs), elemental carbon (EC, diesel indicator), particulate matter (PM2.5), and a suite of metals declined from 1998 to 2006 in NYC due to policy interventions. PAH levels from personal monitoring of pregnant mothers participating in the Columbia’s Center for Children’s Environmental Health birth cohort study, and EC, PM2.5, and metal data from five New York State Department of Environmental Conservation stationary monitors were compared across sites and over time (1998–2006). Univariate analysis showed a decrease in personal PAHs exposures from 1998 to 2006 (p < 0.0001). After controlling for environmental tobacco smoke, indoor heat, and cooking, year of personal monitoring remained a predictor of decline in Σ8PAHs (β = −0.269, p < 0.001). Linear trend analysis also suggested that PM2.5 declined (p = 0.09). Concentrations of EC and most metals measured by stationary site monitors, as measured by ANOVA, did not decline. Across stationary sites, levels of airborne EC and metals varied considerably. By contrast PM2.5 levels were highly intercorrelated (values ranged from 0.725 to 0.922, p < 0.01). Further policy initiatives targeting traffic-related air pollutants may be needed for a greater impact on public health.
