WHAT BIOLOGICAL POLLUTANTS CAN BE LURKING IN A HOME'S AIR?
According to the EPA Environmental Protection Agency there are several biological pollutants that affect indoor air quality. Biological contaminants include bacteria, viruses, animal dander, household dust, mites, cockroaches, and pollen.
There are many sources where these pollutants come from. Many of these particles are small enough to be inhaled.
- pollens, which originate from plants
- viruses, which are transmitted by people and animals
- bacteria, which are carried by people, animals, and soil and plant debris
- household pets, which are sources of saliva and animal dander (skin flakes)
- droppings and body parts from cockroaches, rodents and other pests or insects
- viruses and bacteria
- The protein in urine from rats and mice is a potent allergen. When it dries, it can become airborne.
- Contaminated central air handling systems can become breeding grounds for mold, mildew and other sources of biological contaminants and can then distribute these contaminants through the home
