Human being is exposed to POP (persistent organic pollutants) in different ways. These pollutants may, for example, be transmitted to children through mother's milk. In general, they can be transmitted to the human beings by contact with pesticides and especially DDT.

After the development of industrial activities, today we find traces of chemical pollution everywhere in the world. It must be noted that Arctic is not safe from this situation. Large traces of DDT have been detected in the blood and adipose tissues of this region's inhabitants.

Exposure to POP can have different types of effect on the health:

• dizziness and headaches
• chloracne - skin disease
• problems of the immunity system:
• behavioural problems,
• tumours and
• cancers and
• reproduction problems.
