Paragraph 7
The sites of sampling points should be selected in such a way as to provide data on—
(a)
the areas within zones where the population is likely to be directly or indirectly exposed to the highest concentrations averaged over a calendar year;
(b)
concentrations in other areas within zones which are representative of the exposure of the general population;
(c)
deposition rates representing the indirect exposure of the population through the food chain.
