Impact & Risks
Air quality conditions are generally safe for most individuals, but sensitive groups, such as children, the elderly, and those with respiratory conditions, should remain cautious. On August 28, the 'Moderate' PM2.5 levels may pose minor health risks to sensitive individuals. Ground-level ozone and particulate matter are the primary pollutants of concern, with potential to irritate respiratory systems during prolonged exposure.
