**Primary Article: Declining Air Quality in Tijuana and Mexicali Sparks Health Concerns**
As of Sunday, October 27, 2024, the air quality in Tijuana and Mexicali has deteriorated significantly, raising alarms among health officials and residents alike. Tijuana has issued a renewed alert for poor air quality due to particulate matter, while Mexicali escalated to a “very poor” air quality status. These concerns were highlighted following preliminary environmental monitoring conducted by the Secretariat of Environment and Sustainable Development.
In Mexicali, PM 2.5 particle levels reached 103, above the recommended level of 15 for good air quality. Similarly, Tijuana recorded a PM 2.5 level of 67, classifying it as poor air quality. This follows a series of alerts that saw both municipalities grappling with these environmental concerns, which temporarily subsided in Tijuana on Saturday only to return the following day.
Local authorities have issued guidelines to protect public health, particularly for vulnerable groups such as individuals over 60, children under 12, and pregnant women. Residents are advised to limit outdoor activities, especially those with respiratory conditions. Additionally, several measures have been recommended to curb pollution, including reducing personal vehicle use, reporting fires promptly, refraining from using fireworks, and avoiding activities that produce particulate emissions.

Recent air quality alerts in Tijuana and Mexicali reflect a larger issue of pollution along the US-Mexico border. Both cities have experienced increased levels of particulate matter, primarily from industrial emissions, vehicle exhaust, and other sources. These pollutants pose health risks, contributing to respiratory and cardiovascular conditions among residents.
According to a recent study, Tijuana and Mexicali have become pollution hotspots largely due to rapid urbanization and industrial activity in the region. Efforts to address these issues have led to collaborations between US and Mexican environmental agencies, focusing on cross-border initiatives aimed at reducing emissions.
Public health officials stress the importance of community involvement in combating air pollution. By promoting public awareness and working together with local industries, significant strides can be made in improving air quality and ensuring a healthier environment for future generations.
