How far are these estimates reasonable? Clearly, given the simplifications, the level of
accuracy of these estimates is probably not too high for any country listed, but the range of the
totals within which the real loads lay is acceptable. Taking Italy as a test country, which is not
only best known, but also the major relative contributor to the Mediterranean load, her total
nitrogen export should range between 0.3 to 1 million t/year, and her phosphorus export between
0.027 and 0.058 million tones. Marchetti (1987) estimated the generated total nitrogen load to
0.66 million tones (of which 27% originating from domestic sewage and industry), and the
generated total phosphorus load to 0.048 million tones (of which 54% domestic and industrial).
This corroborates the range of our estimates. Accordingly, one may conclude that the basic
diffused load lay between 60 to 80% for nitrogen, and between 20 to 40% for phosphorus.
Regarding other countries, comparison can be made only for
