What is the most common way for pesticides to enter the human body?

The most common way for pesticides to enter the human body is through dermal absorption. This method occurs when pesticides come into direct contact with the skin. The skin can absorb various substances, including certain chemicals found in pesticides. Factors such as the concentration of the pesticide, the duration of exposure, and the condition of the skin (for example, cuts or abrasions can enhance absorption) significantly influence the extent of dermal absorption.

While inhalation, ingestion, and injection are also pathways for pesticide exposure, they are not as prevalent as dermal absorption in everyday scenarios involving pesticide application, particularly for agricultural and professional applicators. Inhalation can occur when pesticides are aerosolized or applied in a manner that creates fine droplets in the air, while ingestion typically happens accidentally, for instance, if pesticides are improperly stored. Injection would usually only occur in specific and unusual situations involving accidents, rather than common pesticide handling. Understanding dermal absorption is crucial for implementing safety measures and protective practices to minimize risks during pesticide application.
