Children take a special place, which influences the environment (in the broadest sense) on health. For this reason, health and environmental authorities, paediatricians and environmental medicine frequently with questions of the special sensitivity of children to environmental influences from the face.

• But where are the particular hazards for children?
• Respond all children equally and always sensitive than adults?
• Where are the age limits and what actually makes children vulnerable?

Ensure that children and teenagers watching often in the focus of the considerations and concerns are, there are a number of good reasons:

1) embryos, fetuses and children are now in somatic (physical) and functional development. Development are generally static, differentiated systems.

2) Many physiological and metabolic conditions vary depending on their age. This is particularly true for the newborn period in which the metabolism ( "metabolism") and excretion of metabolic products, medicines and pollutants slowed and sometimes can be accelerated. The size of the institutions, water, energy sales and respiration are based on body weight or body surface, quite different in children than in adults.

3) behavior and exposure in childhood are different than in later age. Children are physically active, they drink and breathe - in relation to body weight - more than adults, they talk more often and longer on the outside.

4) The man stands at the end of a long food chain, during which contaminants and residues, particularly long-lived lipophilic (fat soluble) substances in fat and - for the fed infant particularly important - in breast milk can enrich.

5) Children often have a long life ahead of them. A trouble-free development in childhood is a good basis for health in adulthood.

6) Finally, allergies and especially the neurodermatitis, for the addition of genetic disposition environmental factors (in the broadest sense) are responsible, especially in children frequently.
