Evaluation: There is inadequate evidence in humans for the carcinogenicity of hydrazine. There is sufficient evidence in experimental animals for the carcinogenicity of hydrazine. Overall evaluation: Hydrazine is possibly carcinogenic to humans (Group 2B). [IARC. Monographs on the Evaluation of the Carcinogenic Risk of Chemicals to Man. Geneva: World Health Organization, International Agency for Research on Cancer, 1972-PRESENT. (Multivolume work)., p. V71 1006 (1999)
Hydrazine's production and use as a chemical intermediate, reducing agent, as rocket fuel(1) and as a boiler water treatment agent(2) may result in its release to the environment through various waste streams(SRC).

PLUTONIUM CASRN: 7440-07-5
An extremely poisonous radioactive material. The permissible levels for plutonium are the lowest for any of the radioactive elements. This is occasioned by the concentration of plutonium directly on bone surfaces, rather than the more uniform bone distribution shown by other heavy elements. [Lewis, R.J. Sax's Dangerous Properties of Industrial Materials. 9th ed. Volumes 1-3. New York, NY: Van Nostrand Reinhold, 1996., p. 2724
Major Uses:
The short-lived isotope 238Pu has been used in radioisotope generators in unmanned space satellites, lunar and interplanetary spaceships, heart pacemakers /discontinued/, and (as 238Pu-Be alloy) neutron sources. [Kirk-Othmer Encyclopedia of Chemical Technology. 4th ed. Volumes 1: New York, NY. John Wiley and Sons, 1991-Present., p. V19 (96) 412]
Contamination of food, water, hands, or careless handling are the main causes of radionuclide ingestion. /Radionuclides/ [Seiler, H.G., H. Sigel and A. Sigel (eds.). Handbook on the Toxicity of Inorganic Compounds. New York, NY: Marcel Dekker, Inc. 1988., p. 811]
L'uso di materiali alternativi dovrebbe essere un argomento che sta a cuore di chi si pone dei problemi di sostenibilitą di queste attivitą.
