The National Building Research Organization (NBRO) has issued a warning about declining air quality in several parts of Sri Lanka due to prevailing weather conditions. Air quality levels in key cities such as Jaffna and Colombo have reached slightly adverse levels, posing potential health risks to residents.
Current Air Quality Data
The NBRO provided the following Air Quality Index (AQI) readings:
- Jaffna: AQI 130
- Colombo: AQI 120
Both cities have surpassed the recommended AQI threshold of 50, indicating poor air quality.
Meanwhile, the air quality in Nuwara Eliya and Badulla remains at a moderate level, suggesting less immediate health concerns but still warranting caution.
Public Health Advisory
Dr. Ajith Gunawardena, media spokesperson for the Central Environmental Authority, urged individuals experiencing breathing difficulties to seek medical advice immediately. Vulnerable populations, including children, the elderly, and individuals with respiratory conditions, should limit outdoor activities in affected areas.
Comparative Scenario: India
Sri Lanka’s air quality concerns mirror recent reports from India, where air pollution levels have risen due to similar weather conditions, industrial emissions, and vehicular exhaust. Several cities in India recorded AQI levels well above the hazardous mark, intensifying efforts to curb pollution and protect public health.
Environmental Impact
- Health Risks: Prolonged exposure to poor air quality increases risks of respiratory illnesses, cardiovascular problems, and reduced lung function.
- Climate Effects: Elevated air pollution contributes to greenhouse gas emissions, exacerbating global warming.
- Ecological Damage: Fine particulate matter (PM2.5 and PM10) affects soil quality and water bodies, leading to a decline in biodiversity and agricultural productivity.
- Visibility Reduction: High pollution levels can reduce visibility, impacting transportation and tourism sectors.
Call for Action
Authorities emphasize the importance of adopting measures to improve air quality, including:
- Reducing vehicle emissions through public transport use and carpooling.
- Implementing stricter industrial emission controls.
- Enhancing green cover to act as natural air purifiers.
Conclusion
The deteriorating air quality in Sri Lanka and its regional neighbors highlights the urgent need for collaborative and proactive measures to combat air pollution. As weather patterns evolve, continuous monitoring and public awareness are essential to minimize health and environmental impacts.
