What are some of the symptoms of mild poisoning?

Mild poisoning can manifest through a variety of symptoms, and headaches, fatigue, and sore throat are commonly associated with this level of toxicity. These symptoms indicate that the body's systems are reacting negatively to a toxic substance, signaling distress without severe impairment.

Headaches can occur as a result of chemical exposure affecting the central nervous system or causing dehydration. Fatigue suggests that the body is expending extra energy to combat the effects of the toxin, leading to a general sense of tiredness and lack of energy. A sore throat may develop due to inhalation of irritants, indicating that the respiratory system is also being affected.

Other options, while they may represent symptoms of poisoning, typically indicate more severe levels of toxicity. Vomiting, for example, is a common response to more acute poisoning and signifies the body's attempt to expel harmful substances rapidly. Fainting and dizziness are also serious symptoms that typically occur when poisoning has progressed to a more severe stage, potentially indicating a significant systemic impact. Thus, the symptoms listed in the correct answer represent a milder reaction, while the other symptoms suggest more serious conditions that require immediate medical attention.
