Furthermore, rock phosphates also contain impurities, such a fluorine, cadmium and arsenic which, if not removed in the production process, make them unsuitable for animal nutrition. Research has shown that the maximum safe level of fluorine in the total diet is 60-100 ppm for tle and 100-200 ppm for sheep (Phillips et al. 1960).
