Which statement about pesticide exposure routes is true?

1. Studies show that 97% of body exposure occurs during spraying by inhalation

2. Eating, drinking, or smoking without washing hands can transfer pesticides to the mouth

3. Pesticides are absorbed more through the scalp than through the palms and forearms

4. Skin contact is the most significant route of pesticide exposure

The correct answer is: Eating, drinking, or smoking without washing hands can transfer pesticides to the mouth

The statement regarding eating, drinking, or smoking without washing hands transferring pesticides to the mouth accurately reflects a significant concern in pesticide safety. Pesticide residues can adhere to hands after handling products or working in treated areas. If individuals do not wash their hands before engaging in activities such as eating or smoking, they risk transferring harmful chemicals to their mouths, which can lead to ingestion of these substances. This route of exposure is particularly concerning because it bypasses the body's natural defenses and can lead to immediate and severe health impacts. This understanding highlights the importance of hygiene practices among pesticide applicators and anyone who handles such chemicals. Regularly washing hands can significantly mitigate the risk of inadvertent ingestion and can be a key measure in promoting overall safety and health.
