Sampling sites (humans)

4 university cities as sampling areas.

Sampling in the human field is not designed to mirror the sampling areas selected for environmental specimens on the basis of ecosystems, because although human beings today are still part of their environment they are difficult to attribute to representative ecosystems due to their mobility, widely varying conditions at home and at work, and differentiated patterns of food distribution and consumption.

Clearly, therefore, only the selected sampling sites are of any regional relevance.

With individuals and groups moving home in a mobile society, almost the entire country is represented, although there has been a preference for covering rural and industrial areas.
