Which method of pesticide exposure acts the slowest on the body?

1. Dermal

2. Inhalation

3. Ingestion

4. Eyes

The correct answer is: Ingestion

The method of pesticide exposure that acts the slowest on the body is ingestion. When pesticides are ingested, they must pass through the digestive system before entering the bloodstream. This process takes time, as the body breaks down the chemicals in the stomach and intestines, which can delay the onset of symptoms or effects. The absorption rate is generally slower compared to other exposure methods. Inhalation allows pesticides to enter directly into the respiratory system and can result in rapid effects, as substances can quickly cross into the bloodstream through the lung tissue. Dermal exposure can also lead to relatively quick absorption, depending on the skin's permeability and the type of pesticide used. Eye exposure can lead to immediate irritation but may not always result in systemic effects quickly. Overall, the digestive process involved in ingestion is what primarily contributes to it being the slowest route of pesticide action in the body compared to inhalation, dermal, and eye exposure.
