Volatile organic compounds, VOCs, are air pollutants widely produced by biogenic and anthropogenic sources. This work quantitatively studied the presence of these gases in the internal and external environments of schools, comparing one in an urban area (La Salle School, Canoas, RS) and another in a rural area (Santa Cassia Farm School, Nova Santa Rita, RS). The aim of this study was to compare if this environmental differences (location) influence their gases concentration. Monitoring campaigns were conducted for 6 months, occurring every 2 weeks in both schools during class hours, 1 day indoors and 1 day outdoors. The results showed higher concentrations of total volatile organic compounds in the urban school external environment compared with the same rural school environment and, in the comparison between environments, the internal environments of the two schools obtained higher VOC concentrations than the external ones, except in November and December at the urban school.
挥发性有机化合物（VOCs）是广泛由生物源和人为源产生的空气污染物。这项工作定量研究了这些气体在学校内部和外部环境中的存在情况，比较了一所位于城市地区（南里奥格兰德州卡诺阿斯的拉萨尔学校）和另一所位于农村地区（南里奥格兰德州新圣丽塔的圣卡西亚农场学校）的学校。本研究的目的是比较这种环境差异（位置）是否会影响它们的气体浓度。监测活动进行了6个月，在两所学校上课时间每两周进行一次，在室内进行1天，在室外进行1天。结果表明，与同一农村学校环境相比，城市学校外部环境中的总挥发性有机化合物浓度更高，并且在环境比较中，两所学校的内部环境获得的挥发性有机化合物浓度高于外部环境，但城市学校在11月和12月除外。
