Chronic Daily Intake
01/23/26
“How can we calculate the amount of contaminant a person is exposed to daily?”
People are exposed to all kinds of substances throughout the day, whether it’s from the food we eat or the air we breathe. Some of these substances are harmful and can lead to health problems. We can measure how much of these contaminants we expose ourselves daily through Chronic Daily Intake. Chronic daily intake is typically expressed as milligrams of substance per kilogram of body weight per day. The US E.P.A uses chronic daily intake as part of health hazard assessment.
