Bioaerosols are airborne particles derived from plants, animals or are living organisms, including viruses, bacteria, fungi , and mammal and bird antigens. Bioaerosols can range in size from roughly 0.01 micrometer (virus )to 100 micrometer (pollen). These particles can be inhaled and can cause many types of health problems, including allergic reactions (specific activation of the immune system), infectious disease (pathogens that invade human tissues), and toxic effects (due to biologically produced chemical toxins ). The most common outdoor bioaerosols are pollens from grasses, trees, weeds, and crops. The most common indoor biological pollutants are animal dander (minute scales from hair, feathers, or skin), dust mite and cockroach parts, fungi (molds), infectious agents (bacteria and viruses), and pollen.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
Modern Language Association
The Chicago Manual of Style

- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
