The 4 Factors in Air Pollution
— how indoor air quality problems start and spread (such as odors of terpenes from growing marijuana), and are controlled:
(1) Pollutant sources emit contaminants (different gases or particles, at different rates).
- Terpenes evaporate from growing plants.
- Reduce odors with charcoal adsorption.
(2) Pathways connect pollutant sources to the occupants (via air, dust, or contact).
- Terpenes follow the many room penetrations.
- Reduce odor movement by sealing penetrations.
(3) Pressure differences are driving forces that move pollutants (fans, wind, heat/gravity).
- Terpenes push out into neighboring spaces.
- Reduce room pressure with exhaust ventilation.
(4) People (occupants) are individuals (with unique tolerance, sensitivities, reactions).
- Terpenes have a recognizable unique odor.
- Reduce odors enough to avoid problems.
