Intake of PCDD/F from fish in Beneris: Difference between revisions

Revision as of 15:03, 21 October 2008

Scope

Intake of PCDD/Fs from fish describes the exposure to polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) due to fish consumption in the Beneris population.

Definition

Intake of PCDD/Fs from fish is represented as a continuous variable and is indexed by variable age. It applies to adult Beneris population (age groups 18-55yr and 55yr+) and to indicators such as remaining lifetime risk of cancer in adults and risk of developmental dental defects.

Data

Lifetime cancer risk associated with PCDD/Fs is usually estimated using cancer slope factor (CSF) and the lifetime average daily dose (LADD). Therefore the intake of PCDD/Fs from fish is expressed as LADD. LADD is calculated as a product of average daily dose (ADD) and the ratio of exposure duration and lifetime, where ADD is the product of concentration of PCDD/Fs in fish and fish intake rate (daily intake of fish) divided by the body weight (kg).

It is assumed that the exposure duration for people from a given age group is the number of years this age group covers. In other words it is assumed that people from a given age group are exposed to PCDD/Fs from the time of entry to this age group until the time of exit from this age group. For example the exposure duration for age group 18-55yr is 37 years.

Moreover, the average lifetime is 82.9 and 75.9 for Finnish women and men, respectively
