What is the most common route for pesticide poisoning?

1. Inhalation

2. Oral

3. Dermal

4. Injection

The correct answer is: Dermal

The most common route for pesticide poisoning is dermal exposure. Pesticides can enter the body through the skin, especially when protective clothing is not worn or if there is accidental spillage during application. The skin is a large organ, and many pesticides can be absorbed through it, leading to systemic toxicity. This route is particularly concerning because individuals may not immediately realize they have been exposed, and the effects can develop over time. Inhalation is a potential route and is significant, particularly for fumigants or aerosolized pesticides, but dermal exposure tends to occur more frequently in everyday use scenarios. Oral ingestion is commonly associated with accidental poisoning, especially in children, but it is less likely for professional applicators who follow safety protocols. Injection is the least common route in the context of pesticide exposure and usually occurs only in very specific and rare circumstances, such as accidental injury with a contaminated needle. Understanding the primary routes of exposure, particularly dermal absorption, is crucial for implementing effective safety measures and minimizing the risk of pesticide poisoning in both professional and residential settings.
