Towards establishing air quality guidelines for Pakistan

Area of Science:

• Environmental Science
• Public Health
• Toxicology

Background:

• Pakistan has National Environmental Quality Standards for pollutants but lacks ambient air quality guidelines.
• A reliable epidemiological and toxicological monitoring system is absent in Pakistan for establishing air quality guidelines.
• Existing air pollution data in Pakistan is insufficient for evidence-based guideline development.

Purpose of the Study:

• To propose national air quality guidelines for Pakistan.
• To address the absence of established ambient air quality guidelines in the country.
• To provide a basis for environmental health policy and air pollution management.

Main Methods:

• Review of World Health Organization (WHO) air quality guidelines.
• Analysis of air quality standards from Eastern Mediterranean and South-East Asia Regions.
• Evaluation of available air pollution data specific to Pakistan.

Main Results:

• Proposed national air quality guidelines for six major air pollutants.
• Identification of key pollutants requiring regulatory attention in Pakistan.
• Benchmarking against international and regional standards.

Conclusions:

• The proposed guidelines offer a crucial step towards improving air quality management in Pakistan.
• These guidelines can serve as a foundation for developing a national air quality monitoring system.
• Addressing air pollution through evidence-based guidelines is essential for public health protection.
