Humans enter in contact with different air pollutants primarily
via inhalation and ingestion, while dermal contact represents
a minor route of exposure. Air pollution contributes, to
a great extent, to the contamination of food and water, which
makes ingestion in several cases the major route of pollutant
intake (Thron, 1996). Via the gastrointestinal and respiratory
tract, absorption of pollutants may occur, while a number of
toxic substances can be found in the general circulation and
deposit to different tissues. Elimination occurs to a certain
degree by excretion
