Biological pollutants are living organisms or have come from living organisms. They travel through the air and are invisible most of the time. Some of the more common biological pollutants you will find indoors are dust mites and cockroach parts, bacteria and viruses, pollen, and animal dander.
What conditions do biological pollutants thrive in? It should be mentioned that these substances are found in all homes so you will not be able to completely remove them, but there are some conditions that make the problem worse. To support the growth of biological pollutants, moisture and nutrients are required. We know there are many areas in the home that provide these conditions such as bathrooms, damp basements, humidifiers, and air conditioners. Modern construction and materials can also contribute to the growth of some biological pollutants because, reducing the amount of air that comes from outside into the home, can result in higher moisture levels indoors.
How can you determine whether biological pollutants in your home are the cause of some of your health problems? Our next blog will discuss this.
