Indoor Air Quality: part II--what it does.

Area of Science:

• Environmental Health
• Occupational Health
• Public Health

Background:

• Elevated carbon dioxide (CO2) levels, measured at 2,000 parts per million (ppm), were detected in North High School, significantly exceeding the state standard of 800 ppm.
• High CO2 levels signal inadequate air circulation, where fresh air intake is insufficient and stale air is not effectively vented.
• Poor indoor air quality (IAQ) in educational settings is linked to reduced academic performance and increased student absenteeism due to illness.

Purpose of the Study:

• To assess the implications of elevated CO2 levels and poor IAQ in a school environment.
• To determine the potential health and safety risks associated with inadequate ventilation in schools.
• To outline the responsibilities and actions of a school nurse in response to identified IAQ issues.

Main Methods:

• Air quality sampling was conducted in multiple rooms at North High School.
• CO2 levels were measured and compared against established state standards.
• The potential health and safety risks were evaluated based on IAQ principles and EPA guidelines.

Main Results:

• CO2 levels in several school rooms were found to be 2,000 ppm, far above the optimal 800 ppm.
• The high CO2 readings indicate a significant issue with the school's air circulation and ventilation system.
• Poor IAQ poses potential health risks, especially if chemicals are used, and can negatively impact student learning and well-being.

Conclusions:

• The detected high CO2 levels necessitate immediate attention to improve indoor air quality at North High School.
• Implementing enhanced ventilation strategies is critical to mitigate health risks and support a conducive learning environment.
• School nurses play a vital role in identifying and addressing environmental health hazards like poor IAQ to protect student health and academic success.
