What method is the farmer using to protect against contaminants while spraying pesticides?

The method of protecting against contaminants while spraying pesticides revolves around minimizing the absorption of harmful chemicals into the body. This is particularly significant because pesticides can enter the body not only through inhalation or ingestion but also through contact with the skin. By preventing absorption, the farmer is effectively reducing the risk of these chemicals entering the bloodstream and causing harm.

Utilizing protective gear such as gloves, long sleeves, and other barriers helps ensure that the skin does not come in contact with the pesticide, thus minimizing the risk of absorption. This is crucial for maintaining both the farmer's health and the safety of the surrounding environment.

While inhalation, skin contact, and ingestion are all important considerations, the focal point in this scenario is specifically on preventing absorption through the skin, which directly addresses how contaminants can enter the body during pesticide application.
