Lead poisoning is often called a “silent” danger because the symptoms can look like everyday problems or common illnesses. People may feel tired, irritable, have headaches, or stomach pain without realizing lead could be the cause.
You also can’t see, smell, or taste lead in water, food, or old paint. The only reliable way to know if someone has been exposed is through a blood lead test.
Many people don’t realize that there is no safe level of lead exposure. Even very small amounts can permanently harm the brain and nervous system, especially in children. Because symptoms are often mild or delayed, lead can build up in the body over time—especially in the bones—without a person knowing.
