[1]黑碳（BC）和一氧化碳（CO）之间的关系进行了分析，从两个地点在墨西哥城和五个城市地区在德国的测量。所有站点的BC和CO之间的相关系数均大于0.90。BC与CO线性回归线的平均斜率在德国为2.2 μg mg−1，在墨西哥城为1.1 μg mg−1。影响BC与CO关系的最重要因素似乎是柴油与汽油的使用比例以及特定区域车辆的燃烧效率。这项分析的结果表明，在城市地区的CO测量可以用来估计BC质量时，直接测量不可用。
[1] The relationship between black carbon (BC) and carbon monoxide (CO) has been analyzed using measurements from two sites in Mexico City and five urban areas in Germany. The correlation coefficient between BC and CO is greater than 0.90 for all sites. The average slope of the linear regression line for BC versus CO is 2.2 μg mg−1 for German sites and 1.1 μg mg−1 in Mexico City. The most important factors that affect the BC to CO relationship appear to be the ratio of diesel to gasoline usage and the combustion efficiency of vehicles in a particular area. The results of this analysis suggest that CO measurements in urban areas can be used to estimate BC mass when direct measurements are not available.
