The idea that the earth is a closed system and that soil, like other mediums, is polluted by human activities, is very recent, hardly thirty years old. The chief preoccupation has been with water pollution, a conviction that, sooner or later, all the pollutants found in water were the principal cause of the emergence of aquatic ecotoxicology. Yet, the existence of polluted soils has been cited since ancient times. Greek and Roman writers remarked that the contamination of water and air near mines had adverse effects on plants, domestic animals, and humans. But soil pollution is not as visible as water pollution, and to acknowledge that soils can be polluted goes against the belief—still very widespread—that they have an unlimited capacity to purify themselves. Perceptions have evolved: DDT pollution, the Seveso catastrophe (1976), urban pollution by pyralene electric trans¬formers (Reims, 1985; Villeurbanne, 1986), and the nuclear fallout at Cher¬nobyl (1986) have clearly shown that environmental pollution is general and that it affects soil as well as other mediums. Ancient practices, such as the spreading of purifying mud around farming areas, earlier con¬sidered a wasteful agricultural amendment, are now being considered again. The quality of soils is of great importance, as emphasized in the report of INSA/INRA/CRIDEAU/CNRS (I2C2, 1994).
