Antigens entering the human body or produced within it cause the production of antibodies. Usually at least a week is needed before appreciable amounts of antibodies can be detected and further exposure to the allergen can produce disease symptoms. The most common symptoms are skin ailments such as dermatitis and urticaria, or eye problems such as conjunctivitis. The worst may be death resulting from anaphylactic shock. Of particular importance in considering the safety of individuals is the possibility of idiosyncratic reactions.

Inhaled particles may also enter the gut (see below). The effective aerodynamic diameter is defined as the diameter in micrometers of a spherical particle of unit density that falls at the same speed as the particle under consideration. Dusts of larger diameter than 10 µm either do not penetrate the lungs or lodge further up in the bronchioles and bronchi where cilia create a flow of mucus, which returns them to the pharynx and from there they go to the oesophagus. This process is known as the mucociliary clearance mechanism.

This confusion is resolved by the proper use of the term bioavailability given below to describe the extent of absorption. 4 Physiologically based pharmacokinetic model (PBPK). The PBPK model is derived from known rates of organ blood flow, the partition coefficient of the chemical between blood and the tissue, and the rates of the process of elimination, such as Vmax and Km for enzymes. PBPK modelling represents a powerful technique for estimating the dose delivered to specific tissues and can facilitate inter-species extrapolation by replacing animal blood flows and enzyme kinetic constants with human data.
