What is a common effect of high bacterial toxin levels in indoor environments?

Reduced air quality is a common effect of high bacterial toxin levels in indoor environments. When bacterial toxins are present in high concentrations, they can negatively impact the air by increasing microbial content and introducing harmful substances. These toxins can lead to various health issues for occupants, including respiratory problems, allergic reactions, and other adverse health effects.

The presence of these toxins often correlates with poor ventilation and moisture control, exacerbating the situation further. This decline in air quality can lead to increased discomfort among occupants and may contribute to the overall deterioration of indoor environments. While enhanced mold growth may sometimes occur in relation to bacterial issues due to moisture conditions, it is not a direct consequence of bacterial toxins themselves. Other options, such as stability of the building structure and increased comfort levels, do not reflect the negative impacts associated with high levels of bacterial toxins.
