Which areas of the body are particularly vulnerable to dermal exposure to pesticides?

1. Hands and feet

2. Scalp, ear canal, and forehead

3. Back and stomach

4. Arms and legs

The correct answer is: Scalp, ear canal, and forehead

The scalp, ear canal, and forehead are particularly vulnerable to dermal exposure to pesticides due to several factors. First, these areas tend to have thinner skin compared to other parts of the body, which can allow for more rapid absorption of chemicals. Additionally, the scalp has numerous hair follicles which can trap pesticide residues, making it an exposed region. The ear canal, being a sensitive area, can also absorb substances quite readily. The forehead is often one of the more exposed areas during pesticide application, especially if protective measures are not thoroughly observed. High humidity and sweat can exacerbate the absorption of pesticides in these areas. Understanding the vulnerabilities of these specific body parts helps in taking proper precautions when handling pesticides, such as wearing protective clothing and using appropriate personal protective equipment (PPE) to minimize exposure.
