What type of indoor air pollutants can low ventilation rates lead to?

Low ventilation rates can lead to the accumulation of harmful substances in indoor environments. When ventilation is insufficient, pollutants generated from various sources, such as building materials, furnishings, cleaning products, or biological contaminants, are unable to disperse effectively. This can result in elevated concentrations of indoor air pollutants, which may include volatile organic compounds (VOCs), particulate matter, and other harmful substances that can detrimentally affect health and wellbeing.

Good ventilation helps to dilute and remove these pollutants, thereby maintaining air quality and reducing the risk of health issues such as respiratory problems, allergies, or other long-term effects. In contrast, options suggesting limited pollutants like increased humidity or purely beneficial substances do not encapsulate the comprehensive range of risks associated with low ventilation rates. Additionally, solely focusing on organic compounds also overlooks the broader spectrum of pollutants that can accumulate in such conditions.
