What are the primary routes of pesticide exposure?

The primary routes of pesticide exposure are through skin, inhalation, and ingestion. Each of these pathways allows pesticides to enter the body and potentially cause harm.

Skin exposure occurs when pesticide sprays or residues come into contact with the skin, which can absorb the chemicals. This route is significant because it can happen through direct handling of pesticides or contact with contaminated surfaces.

Inhalation is another critical pathway, especially for those who work in pest control or agricultural settings, as they may be exposed to pesticide aerosols or vapors during application. The respiratory system can quickly absorb chemicals, leading to immediate effects and long-term health issues.

Ingestion can happen either accidentally or through improper handling practices, such as eating or drinking while working with pesticides. This route is particularly concerning because it can lead to severe poisoning or systemic effects as the pesticide passes through the digestive system.

In contrast, the other options do not encompass the full range of exposure routes available. While ingestion and inhalation are important, limiting it solely to those two routes excludes the significant risks posed by skin exposure. Similarly, focusing only on skin and eye contact or only inhalation overlooks other crucial methods through which pesticides can enter the body. Therefore, the inclusion of all three primary routes in the correct
