Define risk assessment and risk management. Discuss how risk management combines science and other social factors
What will be an ideal response?
The first step in risk assessment determines whether a substance has toxic effects, by measuring dose-response effects of toxicant exposure. The second step assesses the likely exposure that an individual will have to the toxicant including frequency, concentration, and time of exposure. Risk management consists of decisions and strategies to minimize risk. Federal agencies charged with managing risk consider findings in light of economic, social, and political needs and values. Costs and benefits are addressed with regard to both scientific and nonscientific concerns. While economic benefits are generally known, easily quantified, and of a definite and stable amount, health risks are hard-to-measure probabilities that impact a small percentage of people that will suffer greatly. For example, if a pesticide is used, people may suffer, but if it is not used, people may not have enough to eat. Both costs must be considered before banning the pesticide.
