Which of the following is included in the toxicology information on a pesticide label?

The inclusion of effects of exposure in the toxicology information on a pesticide label is critical for ensuring the safe handling and application of the product. This section of the label informs users about the potential health risks and symptoms they may experience if they come into contact with the pesticide, either through skin exposure, inhalation, or ingestion. Understanding these effects allows users to take necessary precautions to protect themselves and others, making informed decisions about the use, storage, and disposal of the pesticide.

In contrast, first-aid instructions, while important, are typically included as a separate section rather than as part of the toxicology information. The chemical structure of the pesticide is relevant for chemists and formulators, but it is not typically detailed on the label to assist users in understanding health risks. Environmental impact is also significant, but it falls under a different category of label information focusing on safety to the surrounding ecosystem rather than on human health specifically.
