Abstract

The Guadalajara Metropolitan Area (GMA) has continuously presented atmospheric pollution problems due to particulate matter with an aerodynamic diameter less than or equal to 10 micrometers (PM₁₀). Therefore, this research aims to evaluate the risk of developing adverse health effects in children from 0 to 10 years old due to the inhalation of PM₁₀ during 2011–2018 in the GMA. As part of the methodology, the daily, monthly, seasonal, and annual average concentrations were calculated using ten monitoring stations that conform to the Jalisco Atmospheric Monitoring System. Subsequently, the daily and annual concentrations were compared with the current national and international regulatory concentrations. Besides, the hazard index was estimated to know the number of times that the concentrations recorded in the GMA exceed the regulatory concentrations. Finally, the risk was characterized by age groups, calendar year, and seasons by estimating the hazard quotient (HQ). The total HQ results ranged from 1.94 to 4.18, indicating that children from 0 to 10 years old who live in GMA have been at high risk of developing adverse health effects from inhaling high concentrations of PM₁₀ that each year exceeded the annual guideline levels established by the current national and international regulation levels.

摘要

由于空气动力学直径小于或等于 10 微米 (PM ₁₀ ) 的颗粒物，瓜达拉哈拉都市区 (GMA) 不断出现大气污染问题。因此，本研究旨在评估 0 至 10 岁儿童因吸入 PM ₁₀而对健康产生不利影响的风险。2011-2018 年在 GMA 期间。作为该方法的一部分，使用符合哈利斯科州大气监测系统的十个监测站计算了日、月、季节和年平均浓度。随后，将每日和年度浓度与当前的国家和国际监管浓度进行了比较。此外，估计危害指数以了解 GMA 中记录的浓度超过监管浓度的次数。最后，通过估计危险商数 (HQ) 以年龄组、日历年和季节来表征风险。HQ 总结果介于 1.94 至 4.18 之间，表明生活在 GMA 的 0 至 10 岁儿童因吸入高浓度 PM 对健康产生不良影响的风险很高₁₀每年都超过了现行国家和国际监管水平所制定的年度指导水平。
