RISK CHARACTERIZATION. In risk characterization, the information, results, and conclusions from the data evaluation, exposure assessment, and toxicity assessment are integrated. Numerical risk estimates calculated for each COPC and exposure route and pathway are combined to estimate total theoretical noncancer hazards and, for carcinogens, total lifetime excess cancer risks. The critical uncertainties affecting risk calculations are also addressed. 6.1 Noncarcinogenic Hazard Noncarcinogenic effects for each exposure route and pathway, and for each chemical are evaluated by comparing an average dose to a RID for the same time period, generally one day. The ratio of the average daily dose to RID is called a hazard quotient (HQ), which is calculated as follows:
