Indoor Air Quality Assessment: Formaldehyde, Benzene, and Nitrogen Dioxide Levels at Warwick House
Overview
This case study examines indoor air quality at Warwick House, comparing measured levels of formaldehyde, benzene, and nitrogen dioxide against EPA, EU, OSHA, NIOSH, and WHO safety standards. The paper finds that all three pollutants exceeded recommended exposure limits and recommends immediate remedial action to protect occupant health.

Warwick House Case Study
According to our research, the levels of formaldehyde, benzene, and nitrogen dioxide observed in the Warwick House Case Study are above the recommended limits set by environmental and occupational health agencies (EPA, 2016; EU, 2019; OSHA, 2019; NIOSH, 2019; WHO, 2021). The Environmental Protection Agency (EPA) in the United States has set the recommended maximum exposure limit for formaldehyde at 0.1 parts per million (ppm) over an eight-hour workday, while the European Union (EU) has set the recommended limit at 0.05 ppm (EPA, 2016; EU, 2019). In the Warwick House Case Study, the average formaldehyde level was 0.27 ppm, above the EPA and EU recommended limits (EPA, 2016; EU, 2019).
Similarly, the Occupational Safety and Health Administration (OSHA) in the United States has set the permissible exposure limit for benzene at one ppm over an eight-hour workday. The recommended limit set by the National Institute for Occupational Safety and Health (NIOSH) is 0.1 ppm (OSHA, 2019; NIOSH, 2019). In the Warwick House Case Study, the average benzene level was 1.03 ppm, above the OSHA permissible limit and the NIOSH recommended limit (OSHA, 2019; NIOSH, 2019). Lastly, the World Health Organization (WHO) has set the annual average limit for nitrogen dioxide at 40 micrograms per cubic meter (µg/m³) (WHO, 2021). In the Warwick House Case Study, the average nitrogen dioxide level was 53.1 µg/m³, above the WHO recommended limit (WHO, 2021).
