Remote stations are of several types: Urban background : Representatives of the exposure of the urban population in general. Of traffic : Located in such a way that their level of pollution is mainly influenced by emissions from a nearby street or road, but very small microenvironments in their vicinity should be avoided. Suburban s: They are located on the outskirts of the city, in the places where the highest levels of ozone are found.
