phosphorus with estimates made by Vighi and Chiaudani (1987) for a few European countries.
Adjusting these values for the residence population Vighi's et al. estimates would give 3,600 t
for Albania, 20,300 t for France, 13,500 t for Greece, 61,000 t for Italy, 22,500 t for Spain, and
4,100 t for Yugoslavia. In terms of diffused source contribution these figures would compare with
the 40 to 50% assumption of the present estimates.
Extending these conclusions to the Mediterranean basin as a whole, then the most
likely actual total nitrogen load from land-based sources would lie within the range of 1.5 to 2.5
million tones, and that of phosphorus between 0.15 to 0.25 million tones. These figures compare
well with known N/P ratios from rivers (river N/P ranging from about 5 to 15, cf. Table 2 and Fig.
4).
