What are the common symptoms of lead poisoning in adults?

The choice highlighting fatigue, headaches, and irritability accurately reflects common symptoms of lead poisoning in adults. Lead poisoning can affect various systems within the body, including the nervous system, which is particularly sensitive to lead exposure.

Fatigue may occur due to the impact of lead on energy production and overall health, as it interferes with the body's ability to absorb essential nutrients. Headaches are a common neurological symptom and can arise from toxic effects on brain function. Irritability can be attributed to the effects of lead on the brain, leading to mood changes and disturbances in mental health.

While symptoms such as nausea and vomiting, severe abdominal pain, and difficulty breathing can occur in lead poisoning cases, they are generally less common in adults compared to the symptoms selected. Nausea and vomiting are more frequently associated with acute poisoning or high levels of lead exposure, while severe abdominal pain and difficulty breathing tend to indicate more severe or specific health issues rather than the typical presentation of lead poisoning in adults.
