Health experts warn that prolonged exposure to these levels may cause asthma attacks, severe breathing difficulties, heart complications, and long-term respiratory illnesses.
They urge residents to wear masks outdoors, use air purifiers if possible, and avoid unnecessary exposure, especially during peak pollution hours.
Environmental specialists attribute the worsening crisis to vehicle emissions, industrial smoke, construction dust, and open waste burning.
