What type of pesticide exposure occurs primarily through skin contact?

Dermal exposure is the correct answer because it specifically refers to the absorption of pesticides through the skin. This type of exposure can occur when individuals handle pesticides directly, such as during application or if they come into contact with contaminated surfaces, clothing, or equipment. The skin can absorb certain chemical formulations, leading to potential health risks.

Inhalation exposure refers to the entry of pesticides into the body through the respiratory system, primarily when spray particles or vapors are inhaled. Oral exposure involves ingesting pesticides, either accidentally or through contamination of food or drink. Environmental exposure describes broader interactions with pesticides present in the surroundings, like in soil or water, rather than a direct contact scenario. Understanding these distinctions is crucial for ensuring safe handling and applying practices to mitigate risks associated with pesticide use.
