Summary

Enclosed and semi-enclosed environments, particularly those in extremely isolated and hostile environments, such as outer space and the deep oceans, present unique challenges in terms of maintaining safe working conditions for the individuals exposed to them. The best approach to view the current concern about greenhouse gases is to revisit the past, particularly through ice core analysis, which can yield a record of thousands of years. Many hazardous gases are present in mines, including sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), and methane (CH4). The study of completely self-contained and renewable environments was attempted with several closed ecosystem experiments in order to better understand the closed environment of the planet we live on. Monitoring and control systems for these environments are highly complex and specialized to meet unique challenges.
