This project investigates how distance from a secondhand smoke source and exposure duration affect indoor air quality. Using a portable air quality monitor, measurements of particulate matter (PM2.5 and PM10), air quality index, volatile organic compounds, and formaldehyde were recorded at set distances from an active smoker over time. Results help illustrate how smoke particles disperse, how long they persist after smoking ends, and what conditions influence their concentration. The study provides data-driven insights into secondhand smoke exposure risks and highlights practical strategies for reducing inhalation of harmful airborne pollutants.
