Lead Exposure and Public Health: Prevention and Medical Treatment Strategies

Lead exposure and its impact on public health: The use of lead dates back several millennia, and its exposure currently represents one of the most important challenges in the field of global public health. The World Health Organization (WHO) estimates that approximately 1.06 million deaths are associated with lead poisoning each year (WHO, n.d.). Although the harmful effects of lead are widely recognized, it continues to be used extensively in various industries, especially in the manufacturing of many products. Serum concentrations and clinical manifestations: Despite advances in toxicological knowledge, a safe threshold for lead in blood has not been established. However, it has been shown that adverse health effects usually occur when blood levels exceed 10 μg/dL in adults. In children, even considerably lower concentrations can trigger clinical symptoms of poisoning (WHO, n.d.). Symptoms are often nonspecific, making diagnosis difficult and requiring a high level of suspicion on the part of medical personnel. In cases of acute exposure, symptoms may include irritability, headache, abdominal discomfort, arthralgia, fatigue, acute kidney injury, and encephalopathy. The latter can progress to severe conditions such as delirium, seizures, and coma. On the other hand, chronic lead exposure can lead to conditions such as high blood pressure, chronic kidney disease, anemia, and alterations in neurocognitive development (WHO, n.d.).
