A detailed analytical study made on samples of Spirulines algae of various origins showed that these microorganisms may present an important telluric contamination, especially demonstrated by high levels of fluorine and arsenic they contain. A long term animal experimentation has been achieved with Spirula Maxima, obtained from the Sosa Texcoco solar evaporator. A diet contained in total proteins 25 p. 100 of dried atomized algae and was given for 75 weeks to Wistar rats. All along the experiment, the animals submitted to that diet showed no difference with control animals fed with caseine. The increase in weight was comparable for control animals and male experimented animals; a slight decrease in weight has been observed for females fed with algae up to the 30th week. At the end of the experiment, a normal frequency of tumours was noted on experimented animals. The cumulative potentiality of certain mineral toxicants, has been evaluated, when abnormal high levels of them have been detected in the Spirulines samples. The fed animals have been killed at definite times all along the experiment and the metals dosed in the body. Such a cumulative potency has been demonstrated for arsenic. On the contrary, in the case of fluorine, even particular dosages in the femoral bone could not show any significant cumulation of that toxicant, comparing with control animals. In conclusion, the authors have not noted any evident toxicity related to the samples of Spirulines tested in rats, whatever these algae were the only source of proteins in the diet. They hope anyway that the exact origin of contamination of these algaes by these metals will be better known to prevent the variations in the composition of industrial samples of Spirulines according to these metals for instance.
