Aging is a phenomenon that describes the change in contaminant bioavailability to soil-dwelling organisms with an increase in soil contact time.... Aging is usually a two-phase process; an early rapid sorption stage(e. g., to clay, soil humic acid, soil-derived metal oxides, etc.) followed by slower reaction processes(e. g., adsorption on condensed organic matter, diffusion into nano-pores, encapsulation). 1, record 1, English, - aging

Le vieillisemment est le phénomène par lequel la biodisponibilité d'un ou de plus d'un contaminant change avec une augmentation du temps de contact. [...] Le vieillissement se déroule habituellement en deux temps : une phase de sorption hâtive et rapide (p. ex., sur l'argile, l'acide humique du sol, les oxydes métalliques provenant du sol), suivie d'une phase de réaction plus lente (p. ex., adsorption sur la matière organique condensée, diffusion dans les nanopores, encapsulation) [...] 1, record 1, French, - vieillisement

... the mechanisms by which indigenous microbial communities in polluted environments affect the speciation and bioavailability of metals must be understood. The focus of this research is on the microbial precipitation of heavy metals as processes for the natural attenuation of metal pollution in estuarine sediments that could lead to a cleaner and safer environment for all animals, including humans. 1, record 2, English, - metal%20pollution
