Which statement accurately describes the toxicity of Category I pesticides?

• A. They can be consumed in large quantities without harm
• B. They require careful handling and have high toxicity
• C. They are slightly toxic and commonly used
• D. They are safe for use without protective equipment

Answer: (B)

Category I pesticides are classified as highly toxic. This means that they pose significant risks to health and safety if not handled properly. When dealing with these chemicals, it is crucial to recognize that they require careful handling and application procedures to minimize exposure and prevent harmful effects. The high toxicity level indicated in this category necessitates the use of protective equipment and adherence to safety protocols, as even small amounts can be hazardous.

The other choices do not accurately reflect the characteristics of Category I pesticides. For example, stating that they can be consumed in large quantities without harm undermines their toxicity and would mislead users about their safety profile. Additionally, referring to them as slightly toxic or safe for use without protective equipment does not align with their classification as highly toxic substances, which emphasizes the need for stringent safety measures.
