Waste Management Specialist — Lesson 2
Lesson 2 covers environmental research, specifically focusing on the Air Quality Index (AQI), which reports daily air quality on a scale of 0–500, with values above 100 considered unhealthy for sensitive groups. It includes monitoring of six criteria air pollutants under the National Ambient Air Quality Standards (NAAQS): particulate matter (PM2.5 and PM10), ground-level ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead.
