Final answer:
Carbon dioxide (CO2) is a colorless, odorless gas that is produced by the human body and is also present in the atmosphere. It plays a crucial role in maintaining the Earth's temperature and is a waste product of cellular respiration in the human body. High levels of carbon dioxide exposure in enclosed environments can have negative health effects.
Step-by-step explanation:
Carbon dioxide (CO2) is a colorless, odorless gas that is produced by the human body and is also present in the atmosphere. It is a normal part of the Earth's carbon cycle and plays a crucial role in maintaining the planet's temperature. In the human body, carbon dioxide is a waste product of cellular respiration and is expelled through the lungs.
While carbon dioxide is not toxic in normal concentrations, high levels of exposure can have negative health effects. In enclosed environments with poor ventilation, such as confined spaces or rooms with malfunctioning gas stoves, the concentration of carbon dioxide can increase and lead to symptoms like dizziness, shortness of breath, and even loss of consciousness.
It's important to monitor carbon dioxide levels in indoor environments and ensure proper ventilation to prevent excessive exposure. The National Institute for Occupational Safety and Health (NIOSH) provides guidelines for safe exposure limits to carbon dioxide in different settings.
