Ambient air measurements collected from 1994 to 1995 were used in a preliminary assessment of potential source and spatial influences in the Ambos Nogales border region (Nogales, Arizona, USA and Nogales, Sonora, Mexico). In this assessment, volatile organic compounds (VOC) and particulate matter (PM) species were used from four sites, two on either side of the border. An examination of median levels and principal component analysis indicated the dominance of soil dusts and mobile sources. Pairwise comparisons of sites for VOCs associated with mobile sources revealed statistically significant differences between sites in the central Nogales area vs. the two sites furthest from the border. Particulate lead at Mexican sites was higher and significantly different vs. US sites. Although further analyses are necessary, findings suggest that local and immediate mobile/other anthropogenic and soil dust influences are present throughout Nogales, with particulate lead from leaded motor vehicle exhaust or soldering operations being a possible influence on the Mexican side.
1994年至1995年收集的环境空气测量数据被用于对安博斯诺加莱斯边境地区（美国亚利桑那州诺加莱斯和墨西哥索诺拉州诺加莱斯）潜在来源和空间影响的初步评估。在此次评估中，从边境两侧各两个站点获取了挥发性有机化合物（VOC）和颗粒物（PM）种类的数据。中位数水平检查和主成分分析表明土壤灰尘和移动源占主导地位。对与移动源相关的VOC站点进行成对比较发现，诺加莱斯市中心的站点与距离边境最远的两个站点之间存在统计学上的显著差异。墨西哥站点的颗粒物铅含量较高，与美国站点有显著差异。尽管还需要进一步分析，但研究结果表明，整个诺加莱斯都存在本地和直接的移动/其他人为及土壤灰尘影响，含铅机动车尾气或焊接作业产生的颗粒物铅可能对墨西哥一侧有影响。
