What does body burden refer to?

Explanation:
Body burden means the total amount of a chemical or its metabolites that has accumulated in the body from all exposures over time. It reflects the cumulative load stored in various tissues and compartments (fat, blood, organs, etc.) and the amount that remains given the body's distribution and elimination processes. This broad view is why the phrase “accumulation of toxins in the body” is the best description. Environmental concentration in air is about exposure levels outside the body, not the internal load. Tissue distribution in the liver looks at one organ, not the whole-body burden. Excretion rate refers to how quickly the body removes substances, not the total amount that has built up.
