The biological limit (also known as "Acceptable Daily Intake" or ADI) is an important term in food safety and toxicology. It indicates how much of a particular substance a person can consume daily without having negative effects on their health.

This value is based on studies Toxicity and absorption of substances is calculated and takes into account factors such as body weight, age and gender. It is used to assess the safety of chemical substances in food, drugs and environmental samples.

The biological limit is an important factor in monitoring and regulating substances that enter our environment and our bodies. This helps to protect the health of the population and minimize the negative effects of chemical substances.

However, it is important to note that biological limits do not represent absolute safety guarantees. Some people may be more sensitive to certain substances than others, and there may also be unforeseen effects when substances are present in combination with other chemical compounds. For this reason, it is important to continually monitor and review biological limits to ensure they reflect the latest scientific knowledge.
