What is a health effect of carbon dioxide?

Carbon dioxide (CO2) is a colorless, odorless gas that is naturally present in the environment. In elevated concentrations, it can pose significant health risks, one of which is asphyxiation. This occurs because high levels of carbon dioxide in the atmosphere displace oxygen, leading to lower oxygen availability for breathing. As a result, individuals exposed to such environments may experience difficulty in breathing, dizziness, disorientation, or even loss of consciousness, which can ultimately lead to asphyxiation if not corrected.

This understanding is particularly relevant for wastewater treatment operators, who may work in confined spaces or areas with limited ventilation where gas concentrations can fluctuate. Recognizing the potential for asphyxiation is crucial for maintaining safety protocols and ensuring proper ventilation in these settings. Other health effects are more related to different substances or conditions.
