Title Identifying Biological Pollutants to Improve the Indoor Environment
Introduction EMSL Analytical offers laboratory testing services, sampling supplies, test kits, air monitoring instruments and building inspection tools to identify biological pollutants in the built environment.

Cinnaminson, New Jersey, May 30, 2023

A wide range of biological pollutants can negatively impact the indoor environmental quality (IEQ) of a home, school, business or any type of building. Some of the more common ones listed by the U.S. Environmental Protection Agency (EPA) include bacteria, mold, viruses, animal dander and cat saliva, house dust, dust mites, cockroaches and pollen.

EPA reports:

There are many sources of these pollutants. Pollens originate from plants; viruses are transmitted by people and animals; bacteria are carried by people, animals, and soil and plant debris; and household pets are sources of saliva and animal dander. 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. 

Hypersensitivity pneumonitis (HP), allergic rhinitis and some types of asthma are all possible health effects from exposure to some of the biological contaminants listed by the EPA. The agency goes on to share that possible symptoms of health problems caused by biological pollutants may include:

  • Sneezing
  • Watery eyes
  • Coughing
  • Shortness of breath
  • Dizziness
  • Lethargy
  • Fever
  • Digestive problems 


“Other biological exposure concerns in the indoor environment include viruses, like coronavirus, or exposure to the bacterium that causes Legionnaires’ disease and Pontiac fever,” said Jason Dobranic, Ph.D., Vice President of Microbiology and Life Sciences at EMSL Analytical, Inc. “To help identify these and other possible indoor exposure risks, EMSL Analytical offers laboratory testing services, sampling supplies, easy-to-use test kits, air monitoring instruments and building inspection tools to detect biological pollutants and optimize indoor conditions.”

EMSL also recently sponsored an educational video about common biological pollutants found indoors that can be seen at: https://youtu.be/cz-h5XGYGNg
