MDARD Michigan Core Pesticide Applicator Practice Exam

Is it true or false that exposure to a relatively non-toxic pesticide will never cause adverse health effects?

1. True

2. False

3. Only during heavy exposure

4. Only if misused

The correct answer is: False

The statement is false because even relatively non-toxic pesticides can lead to adverse health effects under certain circumstances. Although these pesticides are classified as low in toxicity, exposure can vary greatly depending on multiple factors such as the amount and duration of exposure, the method of application, individual sensitivities, and pre-existing health conditions. For instance, some individuals may have allergic reactions or respiratory issues triggered by non-toxic substances due to their unique biochemistry. Additionally, cumulative exposure over time can have an impact that may not be evident immediately. Thus, it is important to approach all pesticide usage with an understanding that any chemical exposure may carry risks, regardless of its toxicity classification.
