Abstract The disorderly growth of metropolitan regions, combined with the lack of efficient air quality management strategies, contributes to the potential increase in O3. That impact might undoubtedly cause harmful and immediate and continuous effects on living organisms. In this sense, the primary objective of this research work is to identify and evaluate the threshold values of the O3 concentration pattern in the expanded region of the Rio de Janeiro Metropolitan Area (RJMA). Landsat images were retrieved and showed that there was an expansion to the east and west of the RJMA at an average rate of 32 km2. year−1. After analyzing the air quality data in the region for the period between 2010 and 2018, excess concentrations of O3 were registered to occur every month and across all weather seasons, mainly from October to March (spring and summer), concerning air quality standards, There are significant differences in ozone violations between Paqueta weather station (t = 184 days, 53.2 %) and Porto das Caxias weather station (t = 105 days, 30.2 %). The annual time series of O3 violations during the study period was highly variable, with peaks in the years 2012 (14.3 ± 20.1 violations), 2013 (12.3 ± 15.7 violations), and 2015 (23 ± 15.7 violations). Furthermore, there was an increase in the value of surpluses of O3 along 2016, marked by a longer period of excess concentration from August to March. Despite advances in environmental legislation, air quality management protocols still lack effective measures to mitigate the impacts of O3 on the environment, which highlights the need for developing timely and additional interdisciplinary investigations in the coming future.

巴西里约热内卢大都市区东部环境管理计划的城市工业扩张和臭氧浓度增加的分析

摘要 大都市地区的无序增长，加上缺乏有效的空气质量管理策略，导致 O3 的潜在增加。这种影响无疑可能对生物体造成有害的、直接的和持续的影响。从这个意义上说，这项研究工作的主要目标是确定和评估里约热内卢都会区 (RJMA) 扩展区域中 O3 浓度模式的阈值。检索 Landsat 图像并显示 RJMA 以平均 32 平方公里的速度向东和西扩展。年-1。在分析该地区 2010 年至 2018 年期间的空气质量数据后，每个月和所有天气季节（主要是 10 月至 3 月（春季和夏季））都记录了过量的 O3 浓度，关于空气质量标准，Paqueta 气象站（t = 184 天，53.2 %）和 Porto das Caxias 气象站（t = 105 天，30.2 %）之间的臭氧违规情况存在显着差异。研究期间 O3 违规的年度时间序列变化很大，峰值出现在 2012 年（14.3 ± 20.1 次违规）、2013 年（12.3 ± 15.7 次违规）和 2015 年（23 ± 15.7 次违规）。此外，O3 的盈余值在 2016 年有所增加，其标志是从 8 月到 3 月的较长时间的过剩集中。尽管环境立法有所进步，但空气质量管理协议仍缺乏有效措施来减轻 O3 对环境的影响，这凸显了在未来开展及时和额外的跨学科调查的必要性。
