Assume the excess lifetime cancer risk for a certain level of exposure to the chemical acrylamide is estimated to be 7.2 x 10-3. This risk is ____________________ generally accepted criteria for follow-up investigation or intervention.

Question

The prompt asks us to evaluate the excess lifetime cancer risk given for a chemical exposure and indicate how it compares to generally accepted criteria for follow-up.

Option under consideration: 'greater than' the generally accepted criteria for follow-up investigation or intervention.

First, interpret the numeric risk: 7.2 x 10^-3 equals 0.0072, which is 0.72%. This represents a probability of developing cancer over a lifetime due to this exposure.

Next, compare this magnitude to typical screening or intervention thresholds used in risk assessment:
- Many regulatory frameworks consider risks on the order of 1 x 10^-4 (0.01%) or 1 x 10^-5 (0.001%) to be screening or trigger levels for further investigation.
- A risk of 0.72% is vastly larger than these common criteria; it is more than 1,000 times greater than 1 x 10^-4 and tens to hundreds of times greater than 1 x 10^-5.

Therefore, the statement that the risk is greater than the generally accepted criteria for follow-up is correct, because 7.2 x 10^-3 exceeds typical low-level screening thresholds that would prompt investigation or intervention.

If one were to consider an alternative view, such as comparing to a “less than” or “equal to” criterion, those would be inaccurate because:
- 'Less than' would imply the risk is below the threshold, which is false since 0.0072 is not a small risk.
- 'Equal to' would be inaccurate because the value is not equal to standard thresholds; it is substantially higher.

In summary, the given excess lifetime cancer risk (7.2 x 10^-3) is well above commonly used criteria for initiating follow-up actions, supporting the choice that the risk is greater than the generally accepted criteria for follow-up investigation or intervention.
