Through which routes of entry are you likely to be exposed during pesticide mixing?

The correct choice highlights the routes of entry for pesticide exposure during the mixing process, which primarily include dermal contact and inhalation. When working with pesticides, handlers may come into direct contact with the chemicals through their skin, especially if protective gear is not used or if spills occur. This dermal exposure can lead to absorption, potentially causing adverse health effects.

Inhalation is another significant route of exposure during mixing. Pesticides can release vapors or be aerosolized, which can be inhaled into the respiratory system as a fine mist or vapor cloud. Proper ventilation and respiratory protection are essential to minimize the risk of inhaling harmful chemicals during mixing.

While the other routes of entry mentioned in the other choices could theoretically occur in different contexts, they are less relevant in the specific scenario of mixing pesticides. Swallowing, for example, primarily relates to ingestion of materials, which is less likely during mixing if proper handling procedures are followed. Overall, the emphasis on dermal and inhalation routes aligns with the practical concerns for safety when handling pesticides.
