Tijuana Air Quality Alert 2024

Tijuana faces poor air quality as an alert is issued due to high PM 2.5 levels. Residents urged to limit outdoor activities and stay vigilant for health concerns.

## Alert Issued for Poor Air Quality in Tijuana

On Saturday, October 12, 2024, Tijuana woke up to an air quality alert due to an “extraordinary atmospheric pollution event.” State authorities have warned that the current air conditions could pose health risks. According to the Baja California Secretary of Environment and Sustainable Development (SMADS), the air quality index is marked orange, indicating poor air quality primarily due to high levels of PM 2.5 particles in the atmosphere.

SMADS advises individuals with cardiorespiratory diseases, those over 60, children under 12, and pregnant women to limit vigorous outdoor activities. For the general public, it is recommended to stay mindful and reduce prolonged exposure where possible.

### Understanding PM 2.5 Particles

Dr. Gabriela Muñoz Meléndez, a researcher at the College of the Northern Border (El Colef), explains that air quality monitoring involves tracking six primary pollutants: lead, carbon monoxide, ground-level ozone, sulfur dioxide, nitrogen dioxide, and suspended particles like PM 10 and PM 2.5. In Tijuana, PM 2.5 particles are leading contributors to both air pollution and respiratory health issues.

While PM 10 particles settle on the lung surface, reducing lung capacity, PM 2.5 particles can penetrate the bloodstream, potentially leading to lung cancer with prolonged exposure. Dr. Muñoz Meléndez emphasizes the danger of these particles and the importance of suitable air quality monitoring—though many monitoring stations in the area are not consistently operational.

## Secondary Article: Increasing Concerns Over Air Quality in Tijuana

Recent updates indicate that Tijuana has been struggling with recurring air quality issues, exacerbated by industrial emissions and vehicular pollution. Environmental groups have called for stricter regulations and improved monitoring systems to ensure public safety. The lack of active monitoring stations affects the real-time assessment of pollutants, thus delaying public awareness and necessary interventions.

Citizens are encouraged to stay informed by checking local air quality reports and adopting preventive measures, such as using air purifiers indoors and wearing masks during high pollution days. It is crucial that the community and local authorities collaborate to address these environmental challenges for a healthier future.
