The figure shows estimated percentage of  children aged 0–19 years in 2019 with elevated blood lead levels: a above 5 μg/dL (level of concern in USA between 2012 and 2021); and b above 10 μg/dL, using data from the Global Burden of Disease5. Panel c shows the estimated mean percent of lifetime earnings lost per child aged 0–9 years due to cognitive losses associated with lead exposure in each country. See Text S4 for details on the derivation of the underlying data.
