Subject field(s)
  • Environmental Studies and Analyses

  • Compartment - Canadian Nuclear Safety Commission
DEF

A single exposure to a substance or multiple exposures occurring within a short time, usually 24 hours or less.

CONT

Experimental exposure may be acute - that is, an exposure in which the dose is delivered in a single event and absorption is rapid. Although this type of exposure is usually short, an acute exposure may produce chronic effects. In contrast, there is a need to assess effects under chronic exposure conditions in which the dose is delivered at some frequency (daily or weekly usually) over a period of time.

  • Toxicologie
  • Biochimie
  • Tiroir - Commission canadienne de sûreté nucléaire
DEF

Exposition unique à une substance, ou série d'expositions, dans un court laps de temps (généralement 24 heures ou moins).

CONT

Il faut [...] faire la distinction entre une exposition aiguë ou chronique et des effets aigus ou chroniques. Ainsi, une seule dose de [...] TOCP produit, chez l'homme, une lésion nerveuse permanente. Une exposition aiguë a donc entraîné un effet chronique.
