What does the term 'ocular' refer to in relation to pesticides?

The term 'ocular' specifically pertains to the eye. In the context of pesticides, it refers to exposure routes involving the eyes, whether through splashes, residues, or airborne particles that may come in contact with this sensitive area. Understanding this term is crucial because eyes are vulnerable to chemical injuries, and appropriate precautions should be taken to protect them during pesticide application or handling. Personal protective equipment, such as goggles or face shields, is often recommended to prevent ocular exposure, underscoring the importance of this route of entry in pesticide safety.

The other options focus on different routes of exposure, which, while relevant to pesticide safety, do not relate to the term 'ocular.'
