Which statement is true regarding the health effects of pesticides?

The statement that health effects from pesticides can vary is true because individuals may respond differently to pesticide exposure based on several factors. These can include the type of pesticide, the level and duration of exposure, the individual's health status, age, and genetic predispositions. Some people may experience mild reactions, while others might suffer from severe health consequences. Factors like pre-existing health conditions or medications can also influence how someone is affected by pesticides. Consequently, understanding that health effects can differ is crucial for evaluating safety and managing risks associated with pesticide use.

The other statements do not accurately reflect the complexities of pesticide health effects. It's important to recognize that while some pesticides can be safely handled by trained individuals, that does not imply that the general population is immune to the effects. Furthermore, suggesting that pesticides pose no risk to the environment is misleading, as many pesticides can have significant ecological impacts.
