Final answer:
The term for an injury or illness from pesticide exposure with symptoms appearing within 24 hours is (C) 'acute'. Acute effects arise quickly after a high level of exposure, whereas chronic effects emerge slowly from long-term, low-level exposure.
Step-by-step explanation:
The term that refers to an injury or illness from pesticide exposure with symptoms that occur within 24 hours is acute. Acute effects are those that occur rapidly after a high level of exposure to a substance and are contrasted with chronic effects, which result from long-term, low-level exposure. While chronic effects are not immediately apparent and may take years to be observed, acute effects are immediate and can be severe.
In the context of pesticide exposure, acute poisoning is of particular concern in developing countries, whereas developed countries often have more control over acute exposure but face challenges with chronic, long-term low-level exposure. Pesticide illness from acute exposure can happen in various settings, such as agricultural fields, greenhouses, stores, or during emergency responses to accidents involving pesticides.
