bioaccessibility n.  |  bioaccessibilité
amount of a chemical presents in the environment that can be ingested by a living organism

bioaccumulation
n.  |  bioaccumulation
1. accumulation process of a chemical by a living organism from its environment
2. approach of environmental quality monitoring through the concentration of a chemical accumulated in a living organism

bioavailability n.  |  biodisponibilité
amount of a chemical presents in the environment that reaches the systemic circulation of a living organism after ingestion

biocoenosis n.  |  biocœnose
biological component of a considered ecosystem

bioconcentration n.  |  bioconcentration
concentration process of a chemical bioaccumulated compared to its environmental content

biodiversity n.  |  biodiversity
the number of species present in a given area

biogeochemical cycle n.  |  cycle biogéochimique

biogeochemistry n.  |  biogéochimie
science that studies the element dynamics between the different natural compartments (lithosphere, hydrosphere, atmosphere, and biosphere)

bioindication n.  |  bioindication
approach of environmental quality monitoring through the biological integrity on the individual or ecological scale (morphology, physiology, community, or ecosystem) under the influence of a pollutant

biological invasion n.  |  invasion biologique
process by which the distribution area of a newly introduced biological species extends to the detriment of curently present species, usually due to human action

biomagnification n.  |  bioamplification
transfer and concentration process of a chemical bioaccumulated throughout the trophic levels
