Considering that carbon dioxide is colorless and odorless, detecting it in the environment at concentrations lower than 40% is challenging. Additionally, the symptoms of poisoning from carbon dioxide are similar to those caused by many other pollutants, lacking distinctive effects. As a result, it is regarded as a hazardous factor in occupational settings. This gas is notably heavier than air and can displace oxygen. OSHA has declared that the average carbon dioxide concentration during an 8-hour workday for adults should not exceed 5000 parts per million (0.5%). Recognizing the significance of this issue, in the spring of 1401 (2022), Behyaar Sanat Company initiated research on simulating and constructing a unit for the removal of carbon dioxide resulting from human respiration in submarine environments.
