Which type of exposure accounts for more than 80% of pesticide poisoning cases?

Dermal exposure is the correct answer because it encompasses the majority of pesticide poisoning cases. Pesticides can penetrate the skin and enter the bloodstream, making dermal contact a significant risk factor for exposure. This mode of exposure is particularly prevalent among agricultural workers and others who handle pesticides, as it can occur unintentionally through skin contact with contaminated surfaces, equipment, or during the application process itself.

In contrast, while oral exposure can also lead to poisoning, it typically represents a smaller percentage of cases because it often requires a deliberate act, such as ingesting pesticide products. Inhalation exposure does pose risks, especially in enclosed spaces or during aerosol applications, but it generally accounts for fewer cases than dermal exposure. Ocular exposure, though hazardous, is less common as well, mainly leading to localized irritation rather than systemic poisoning. Therefore, the significant proportion of pesticide poisoning due to dermal exposure underscores the importance of handling precautionary measures, such as wearing appropriate protective gear and implementing best practices during pesticide application.
