Explain how response to hazards can vary based upon individual differences and type of exposure. Give examples, where appropriate
What will be an ideal response?
Different individuals may be more sensitive to hazards. Differences can be genetically based, can result from varying abilities of the body's organs to detoxify substances, or can be due to a person's overall condition. People in poor health are often more vulnerable to hazards. Sensitivity can also vary with sex, age, and weight. Fetuses, infants, and young children tend to be more sensitive to toxicants because of their small size and rapid growth. Acute exposure, which is high exposure for short time periods, differs from chronic exposure, which is lower exposure over long time periods. Acute exposures are easier to recognize because they often stem from discrete events such as accidental ingestion, oil or chemical spills, or a nuclear accident. Chronic exposure is more common and more difficult to detect and diagnose. Chronic exposure often affects organs gradually, as happens when smoking causes lung cancer or when alcohol abuse induces liver or kidney damage. Pesticide residues on food or low levels of arsenic in drinking water also pose chronic risk.
