Strategies for Risk Analysis

There is no universally accepted definition of risk assessment. Some define it narrowly to mean only the identification of a hazardous substance. Others interpret it to mean the full range of activities, including the risk-benefit analysis and the economic considerations used to make a regulatory decision. 

In this report, we visualise five steps in the identification of mutagenic hazards and the estimation of genetic risks  

Hazard identification. The determination of whether a substance is mutagenic. For this purpose, inexpensive, quick, sensitive tests are needed. 

Hazard characterization A semiquantitative evaluation. Mutagens have vastly different strengths and, even though accurate quantitative evaluation may not be possible, can 

Risk estimation. Hie estimation of effect per unit of exposure. There are two components estimation of mutagenic effects on germ cells (damage) and estimation of effects on health and welfare of future generations (impact).
