The term "contact effects" specifically refers to immediate injury at the site of exposure when an organism comes into direct contact with a pesticide. This can include skin irritation, burns, or other forms of damage that occur rapidly after exposure to the chemical. Such effects are often localized and can manifest as redness, swelling, or lesions where the pesticide has touched the skin or another surface of the exposed organism.

Understanding contact effects is crucial for ensuring safety when applying pesticides, as immediate reactions can provide important indicators of potential hazards associated with particular pesticides. Being aware of these effects also assists in implementing appropriate safety measures to minimize exposure to individuals handling or applying these chemicals.
