exposition aiguë

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.

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.
