Statement on COT principles for assessing risks from less than lifetime exposure or variable exposure over a lifetime
Dietary exposures to chemicals are typically compared to a health-based guidance value (HBGV), for example a tolerable daily intake (TDI), that has been established to be safe for long term exposure. Such values set a level of exposure that is considered acceptable if continued throughout a normal lifetime, i.e. it is an upper amount to which an individual can be exposed daily over a lifetime without a significant risk to health. Sometimes people may be exposed to chemicals at a higher level for a shorter period of time, and this statement contains COT recommendations on possible ways of refining the risk assessment for such less-than-lifetime exposures. The statement includes a flowchart to illustrate the process.
