Which statement about harmful effects of pesticides is false?

The statement that pesticides can cause stomach ailments but not respiratory issues is false because it disregards the potential for respiratory problems associated with pesticide exposure. Many pesticides can indeed be inhaled, leading to various respiratory issues such as irritation of the airways, asthma attacks, and other breathing complications. It is well-documented that inhalation is a common route of entry for pesticide chemicals, making the first statement about inhalation being the most common form of pesticide injury accurate. Furthermore, the risks associated with pesticides often extend beyond just gastrointestinal discomfort; they encompass a broader spectrum of health issues, including serious respiratory concerns. As such, any assertion that minimizes or excludes respiratory health problems is misleading and incorrect.

The other statements highlight valid concerns regarding pesticide exposure. Allergies leading to asthma-like symptoms and skin reactions from herbicides and fungicides are recognized health risks associated with pesticide use.
