bioconcentration
This term is a specialized technical expression used primarily in toxicology, environmental science, and marine biology. It describes a specific mechanism of accumulation where the uptake of a chemical occurs solely from the water phase, distinguishing it from bioaccumulation, which encompasses all possible routes of exposure including diet.
Because it describes a continuous biological process or a measurable state of concentration, it is treated as an uncountable noun. It is typically used in formal scientific reports, regulatory documents, and academic research to quantify the risk of pollutants in aquatic ecosystems.
Meanings
The process by which a chemical substance accumulates in an aquatic organism from the surrounding water, resulting in a higher concentration of the substance in the organism than in the water.
The bioconcentration of mercury in fish is a significant concern for environmental health.
