This study presents a modern mobile laboratory to monitor outdoor air quality in Bucharest, Romania, with a focus on pollutants associated with transportation. Particulate matter (PM., PM), carbon monoxide (CO), ozone (O), sulfur dioxide (SO), nitrogen oxides (NO, NO), and BTEX compounds (benzene, toluene, ethylbenzene, and xylenes) were among the significant pollutants that were examined in the lab. Meteorological variables such wind direction and speed, temperature, humidity, and solar radiation were also routinely observed in order to assess their influence on pollution levels. The study looked at two locations-a bustling city road in Bucharest and a remote community 40 kmawayin Snagov-under a range of weather conditions, including sunny, rainy, warm, and chilly days. The findings showed that the primary source of pollution in the urban area, which had significantly higher pollution levels than the rural site, was transportation. Particularly in the city, alarming concentrations of harmful particulate matter and carcinogens like benzene were found, underscoring the need for continuous air quality monitoring. The weather has a major impact on the dispersal of contaminants. Because of washout effects, rainy days decreased airborne pollutants, but sunny days showed higher pollution deposition. This study highlights the importance of outdoor air quality monitoring, particularly in urban environments, where traffic and weather have a significant impact on pollution levels. These findings provide crucial data that policymakers can utilize to implement targeted pollution control measures that protect human health.
本研究展示了一个用于监测罗马尼亚布加勒斯特市室外空气质量的现代化移动实验室，重点关注与交通相关的污染物。颗粒物（PM.、PM）、一氧化碳（CO）、臭氧（O）、二氧化硫（SO）、氮氧化物（NO、NO）以及BTEX化合物（苯、甲苯、乙苯和二甲苯）是该实验室检测的主要污染物。为了评估风向和风速、温度、湿度以及太阳辐射等气象变量对污染水平的影响，这些变量也会被定期观测。该研究考察了两个地点——布加勒斯特一条繁忙的城市道路以及距离其40公里外位于斯纳戈夫的一个偏远社区——在包括晴天、雨天、温暖和寒冷天气在内的一系列气象条件下。研究结果表明，城区污染水平显著高于农村地区，其主要污染源是交通。尤其是在城市中，发现了有害颗粒物和苯等致癌物的惊人浓度，这凸显了持续进行空气质量监测的必要性。天气对污染物的扩散有重大影响。由于冲刷作用，雨天会减少空气中的污染物，但晴天的污染沉降更高。本研究强调了室外空气质量监测的重要性，特别是在城市环境中，交通和天气对污染水平有重大影响。这些研究结果提供了关键数据，政策制定者可利用这些数据实施有针对性的污染控制措施，以保护人类健康。
