Museums are full of history, but they also hide tiny, invisible threats. Staff in a historical museum started noticing issues with their breathing. This led to a study to figure out what was in the air they were breathing in every day.

The study looked at three different workdays. Scientists used special tools to collect air samples. They wanted to find out how much fungi, bacteria, and endotoxin were floating around. These tiny organisms can cause problems if they get into the lungs.

The results showed that the air was full of these tiny threats. On average, there were about 5, 900 fungi, 1, 800 bacteria, and 7. 93 EU/m3 endotoxin in every cubic meter of air. This is a lot more than what is typically found in a clean environment.

The staff reported feeling sick right away when they entered two specific departments. These areas had much higher levels of fungi compared to other parts of the museum. The most common types of fungi found were Aspergillus and Cladosporium. These fungi can grow in many different conditions, including places with low moisture.

Bacteria levels were highest when staff were present. This suggests that the staff themselves might be contributing to the spread of bacteria. The study also found that handling artifacts increased the levels of fungi and bacteria in the air. This means that the very items the museum is trying to preserve might be making the air worse.

The air samples collected were tested on human cells. The results showed that the air could cause inflammation. This means that the air in the museum could be making the staff sick. The inflammation was linked to the levels of fungi, bacteria, and endotoxin in the air.

The study found that the staff in the two departments with breathing issues were exposed to very high levels of fungi. These fungi can grow in many different conditions, including places with low moisture or water damage. This means that the museum needs to find ways to control the humidity and keep the air clean.

The findings show that museums need to take steps to protect their staff. This could include better ventilation, regular cleaning, and controlling the humidity. It is important to remember that museums are not just about preserving artifacts. They also need to protect the people who work there.
