The toxicity of lead and its effects on child neurodevelopment have been well documented for decades. The dramatic decrease in average blood lead levels in the United States over the past several decades is an undeniable public health achievement. Over the same period it has been recognized that, unfortunately, there is no safe level of lead exposure. The continued presence of lead in water pipes, paint, and soils results in continued elevated blood lead levels (EBLLs) among children, particularly those of lower socioeconomic status. Globally, many nations are still using lead in industrial processes, gasoline, paint, or consumer products. Thus, lead exposure remains an important health concern in the United States and globally.
