Bioaccumulation
Definition
Uptake and retention under specified conditions, not a guarantee of concentrations above the source. An insect can take up, metabolise, retain or eliminate substances from its food or environment. The resulting amount depends on the compound, species, stage and sampling conditions.
- Context
- Entomotoxicology
For example, two insect stages exposed to the same source can retain different amounts of a compound, preventing a simple source-concentration conversion.
Detection in an insect is not a fixed conversion to the original human blood concentration. Uptake does not necessarily mean the insect concentration exceeds its source.
