A high value indicates a strong tendency for adsorption to soil or sediment, rather than remain dissolved in soil solution (or pore water). Strongly adsorbed molecules will not leach or move unless the soil particle to which they are adsorbed moves (as in erosion). Koc of less than 500 indicates little or no adsorption and a potential for leaching. 2, record 1, English, - organic%20carbon%2Dwater%20distribution%20ratio

Le facteur de retard est proportionnel au coefficient de distribution Kd, qui décrit la séparation d’un soluté dissous entre les phases aqueuse et sorbée. Le degré d’adsorption est directement lié au contenu en carbone organique du sol. On sait qu'il existe une relation empirique entre Kd, la fraction massique en carbone organique dans le sol(foc) et le coefficient de distribution carbone organique/eau(Koc) : Kd=foc.

Lunar soil is the fine regolith found on the surface of the Moon. Its properties can differ significantly from those of terrestrial soil. It is essentially devoid of moisture and air, two important components found in soil on Earth. 2, record 2, English, - lunar%20regolith
Record number: 2, Textual support number: 1 OBS
The term lunar soil is often used interchangeably with "lunar regolith" but typically refers to the finer fraction of regolith, that which is composed of grains one centimeter in diameter or less. Some have argued that the term "soil" is not correct in reference to the Moon because soil is defined as having organic content, whereas the Moon has none. However, standard usage among lunar scientists is to ignore that distinction. Lunar dust generally connotes even finer materials than lunar soil, the fraction which is less than 30 micrometres in diameter. 2, record 2, English, - lunar%20regolith

Le régolithe lunaire est le nom donné à la couche superficielle recouvrant la Lune. Il est constitué de grains très fins résultant de la pulvérisation de la surface lunaire par le bombardement micrométéoritique. Il recouvre l’ensemble de la surface de la Lune et s’étend sur une profondeur de 2 à 8 mètres dans les mers et peut même excéder les 15 m dans les terres. Cette fine couche est caractérisée par une très forte porosité de près de 50 %. Sa nature et sa structure sont responsables de l’ensemble des propriétés de rediffusion de la lumière solaire. 3, record 2, French, - r%C3%A9golithe%20lunaire
Record number: 2, Textual support number: 1 OBS
Les «sols» lunaires. La notion de sol pose problème quand on s’intéresse à la Lune ou à une autre planète que la Terre. On définit en effet le sol comme étant une formation superficielle provenant de l'altération des roches sous-jacentes sous l'influence des facteurs climatiques et l'action des êtres vivants. La présence d’une fraction organique en plus de la fraction minérale caractérise donc cette notion. On utilise parfois ce terme de sol pour désigner les couches superficielles formées par l'altération de la croûte lunaire, mais on devrait parler de régolithe. 4, record 2, French, - r%C3%A9golithe%20lunaire
