Traduction de «chronic toxic hazard » (Anglais → Français) :

The criteria for classification of a substance into the categories Chronic 1 to 3 follow a tiered approach where the first step is to see if available information on chronic toxicity merits long-term hazard classification.

“long-term hazard” means for classification purposes the hazard of a substance or mixture caused by its chronic toxicity following long-term exposure in the aquatic environment.

Such an amendment should direct the minister to establish a schedule of priority chronic health hazards, drawing from International Agency for Research on Cancer classifications, California's Proposition 65 list of chemicals that are toxic to reproduction, schedule 1 of CEPA, and other authoritative assessments.

The “relevant components” of a mixture are those which are classified “Acute 1”or “Chronic 1” and present in a concentration of 0,1 % (w/w) or greater, and those which are classified “Chronic 2”, “Chronic 3” or “Chronic 4” and present in a concentration of 1 % (w/w) or greater, unless there is a presumption (such as in the case of highly toxic components (see section 4.1.3.5.5.5)) that a component present in a lower concentration can still be relevant for classifying the mixture for aquatic environmental ...[+++]hazards.
