How much air is inhaled in a minute?
The average person will breathe between 10-15 breaths per minute. Every minute approximately 6 liters of air is inhaled. If that is contaminated, that will soon lead to illness. Some of the inhaled toxins will be expelled from the body by exhaling, coughing and sneezing, but this will not stop some of the contaminated residue from working its way into the blood stream.
What does it mean when you inhale?
What Does Inhalation Exposure Mean? Inhalation exposure is when the body’s airways (mouth and nose) come into close proximity with airborne toxins and pollutants.
What is biologically effective dose?
Biologically effective dose is the amount of contaminant that interacts with the internal target tissue or organ. Illustration of Inhalation Route: Exposure and Dose (U.S. EPA, 1992) The amount of chemical that is absorbed through the lung may vary from the amount of the substance that is inhaled.
What is potential dose?
Potential dose is the amount of contaminant inhaled (i.e., amount that gets in the mouth or nose), not all of which is actually absorbed. Applied dose is the amount of contaminant at the absorption barrier (e.g., respiratory tract) that can be absorbed by the body.
What is an exposure route?
An exposure route exposure route The way a chemical pollutant enters an organism after contact, e.g., by ingestion, inhalation, or dermal absorption. is the way that a contaminant enters an individual or population after contact (IPCS, 2004). Typically, exposure occurs by one of three exposure routes—inhalation, ingestion, or dermal.

For chronic assessments (e.g., cancer), potential lifetime average daily dose (LADD) is calculated in which lifetime (LT, in days) is substituted for AT. In some cases, it may be necessary to calculate an inhalation dose using the equation below.
What is the cause of inhalation?
Inhalation exposure can result from breathing air that is contaminated with particulate matter (e.g., dust), vapors (e.g., volatile or semivolatile contaminants), or aerosols. Individuals can be exposed via the inhalation route during a variety of activities outdoors and indoors.
