What are biological air pollutants?

Biological contaminants include bacteria, viruses, animal dander and cat saliva, house dust, mites, cockroaches, and pollen. There are many sources of these pollutants. Standing water, water-damaged materials or wet surfaces also serve as a breeding ground for molds, mildews, bacteria and insects.

What are the 5 types of biological contaminants?

What is the best example of biological contamination?

Examples of biological contaminants and the problems they cause include:

Bacteria, like Salmonella, which will lead to nausea, vomiting, and diarrhea.
Viruses, such as rotavirus, which will lead to the stomach flu.
Parasites, like Ascaris lumbricoides, a roundworm that will gladly live inside your gut.

What is an example of a biological toxin?

Examples include botulinum toxins (A-G), tetanus toxin, and staphylococcal enterotoxins (A-F), which are produced by bacteria; tetrodotoxin, and ciguatoxin, which are produced by animals; and ricin toxin, tricothecence mycotoxins, and abrin, which are produced by plants.

What are the three main causes of indoor air pollution?

Toxic products, inadequate ventilation, high temperature and humidity are a few of the primary causes of indoor air pollution in our homes.

Asbestos is the leading cause of indoor air pollution.
Formaldehyde is another leading cause of indoor air pollution.

Which air pollutant is a significant indoor and outdoor air pollutant?

Some of these pollutants (e.g., NOx, SO2, O3, PM) are common to both indoor and outdoor environments, and some of them may be originated from outdoors.

What are biological pollutants, how do they affect indoor air quality?

What are biological pollutants, how do they affect indoor air quality? Biological contaminants include bacteria, molds, mildew, viruses, animal dander and cat saliva, house dust, mites, cockroaches, and pollen (see more about Asthma triggers at www.epa.gov/asthma). There are many sources of these pollutants.

What are the different types of indoor pollutants?

Indoor pollutants can be placed into two groups, biologic and chemical. Biologic pollutants include bacteria, molds, viruses, animal dander, cat saliva, dust mites, cockroaches, and pollen. These biologic pollutants can be related to some serious health effects.

Which is an example of a biological pollutant?

Some can even damage surfaces inside and outside your house. Biological pollutants can travel through the air and are often invisible. Some common indoor biological pollutants are: Animal Dander (minute scales from hair, feathers, or skin) Dust Mite and Cockroach parts. Infectious agents (bacteria or viruses) Pollen.

Where can you find biological pollutants in your home?

Even a spotless home may permit the growth of biological pollutants. Two conditions are essential to support biological growth nutrients and moisture. These conditions can be found in many locations, such as bathrooms, damp or flooded basements, wet appliances (such as humidifiers or air conditioners), and even some carpets and furniture.
