Abstract

The main goal of this study is to evaluate the potential risk of high levels of particulate matter with diameter ≤ 2.5 μm (PM_2.5) on children´s health, using PM_2.5 monitoring in the western zone of the city of Rio de Janeiro and health data determined in the same area. Results showed that, during this period, in more than 50% of days PM_2.5 concentration were > 15 µg m^- 3. This value is the maximum concentration to ensure a good air quality according to the WHO guidelines and the Brazilian legislation. Furthermore, in 2023, 28.24% and 5.29% of mortality rates, for children between 1 and 5 years old, were due to respiratory and cardiovascular diseases respectively. On the basis of the particulate matter levels recorded in this study and the WHO AIRQ + software, we estimate that PM_2.5 levels may have contributed to approximately 8.5% of the total number of these deaths and could have been prevented.

里约热内卢市西部地区细颗粒物水平及其对儿童健康的潜在风险

本研究的主要目的是利用巴西里约热内卢市西部地区的PM2.5监测数据和同一地区的健康数据，评估高水平直径≤2.5 μm （PM2.5）颗粒物对儿童健康的潜在风险。结果表明，在此期间，超过50%的天数PM2.5浓度为150µg m- 3。根据世卫组织准则和巴西立法，该值是确保良好空气质量的最大浓度。此外，在2023年，1至5岁儿童的死亡率中分别有28.24%和5.29%是由呼吸系统疾病和心血管疾病造成的。根据本研究记录的颗粒物水平和世卫组织AIRQ +软件，我们估计PM2.5水平可能造成了约8.5%的死亡人数，并且是可以预防的。
