As an environmental health specialist with a focus on air quality and its effects on human health, I can provide an in-depth analysis of the potential health implications of breathing sewer gas.
Firstly, it is important to understand what sewer gas is. Sewer gas is a mixture of various gases that can emanate from sewer systems. The primary components of sewer gas include methane, hydrogen sulfide, carbon dioxide, and other volatile organic compounds (VOCs). These gases are byproducts of the decomposition of organic matter in wastewater.
Methane is a colorless, odorless gas that is a major component of natural gas. It is not toxic but can be dangerous if it accumulates in enclosed spaces due to its flammability and potential to displace oxygen.
Hydrogen sulfide is the gas that gives sewer gas its characteristic rotten egg smell. It is a toxic gas, but as mentioned in the provided reference, it is only harmful at high concentrations. At the levels typically found in a household with sewer gas odors, it is unlikely to pose a significant health risk.
Carbon dioxide is another component of sewer gas. It is a naturally occurring gas that we exhale with every breath. In high concentrations, it can be dangerous because it can displace oxygen in the air, leading to asphyxiation.
Volatile organic compounds (VOCs) are a broad group of organic chemicals that easily evaporate at room temperature. Some VOCs are known to be harmful to human health, causing symptoms ranging from headaches to more severe health issues.
Now, let's address the question: Is it unhealthy to breathe sewer gas? The answer is not straightforward and depends on several factors:
1. Concentration of Gases: The health effects of sewer gas are largely dependent on the concentration of the gases present. At low concentrations, the gases may not pose a significant health risk. However, if the concentration of toxic gases like hydrogen sulfide increases to dangerous levels, it can lead to health problems.
2. Exposure Time: The length of time a person is exposed to sewer gas also plays a crucial role. Short-term exposure to low levels of sewer gas may not have lasting effects, but long-term exposure to higher concentrations can lead to chronic health issues.
3. Individual Sensitivity: People's sensitivity to gases can vary. Some individuals may be more susceptible to the effects of sewer gas due to pre-existing conditions or genetic factors.
4. Ventilation: Proper ventilation can significantly reduce the concentration of sewer gas in a living space, mitigating potential health risks.
5. Source Control: Addressing the source of the sewer gas is essential. This can involve repairing leaks, ensuring proper sewer maintenance, and using airtight seals to prevent gas from entering living spaces.
In conclusion, while sewer gas can contain harmful components, under normal circumstances and with proper ventilation, it is unlikely to pose a significant health risk. However, it is always advisable to address any sewer gas odors promptly to ensure a healthy living environment. If there is a persistent sewer gas odor in your home, it is recommended to consult with a professional to identify and fix the source of the problem.

Answer: Only under extremely unusual circumstances. Although hydrogen sulfide is a toxic gas, it will not harm people at the concentrations that exist in a house with sewer gas odor problems. ... Not enough gas is generated in the sewers for concentrations to approach the dangerous level in the dwelling.
