WHO Health Affects Of Particulate Matter

CES Medical Symposium

• 25 million people today are chronically ill world-wide due to poor air quality

• 4 million people die each year of CO suffocation due to smoke inhalation

• 3 million cardiopulmonary & lung cancer deaths each year are attributable to

PM10 & PM2.5 globally

• 1.6 million premature deaths occur each year from prolong CO ingestion

• 100 ppm of CO causes headache, tiredness, dizziness, nausea within 2 hours of

exposure

• 800 ppm of CO can cause death in less than one hour

• 4000 suicidal cases per year due to over exposure of CO
