14 Αυγ 2024 · CDC’s childhood lead poisoning data. A blood lead test is the best way to measure lead exposure. Children are given a blood test to determine the level of lead in their blood. The amount of lead in blood is referred to as blood lead level (BLL). BLLs are measured in micrograms of lead per deciliter of blood (μg/dL). There is no known safe BLL.
1 Οκτ 2024 · To review the effects of blood lead levels (BLLs) <10 µg/dL in school-age children and adolescents. DATA SOURCES. We searched Medline, Embase, Global health, CINAHL, Scopus, and Environmental Science Collection databases between January 1, 2000, and May 11, 2023. STUDY SELECTION.
11 Σεπ 2023 · We used mean blood lead levels from GBD 2019 by country, as this set of estimates is the most complete on a global scale. These blood lead level estimates are for children up to the age of 18 years, and whether they also pertain to adults is unclear.
28 Φεβ 2019 · Abstract. The purpose of this article is to consider alternate uses of the blood lead reference value for children. There are two possible approaches. Historically the reference value has been used to guide clinical and public interventions for individual children.
17 Μαρ 2021 · Lead can adversely affect child health across a wide range of exposure levels. We describe the distribution of blood lead levels (BLLs) in U.S. children ages 1–11 y by selected sociodemographic and housing characteristics over a 40-y period. Methods:
14 Μαΐ 2021 · CDC uses a blood lead reference value (BLRV) of 3.5 micrograms per deciliter (µg/dL) to identify children with blood lead levels that are higher than most children's levels. The value of 3.5 μg/dL was derived from NHANES data from the 2015-2016 and 2017-2018 cycles.
Many children have a blood lead level exceeding 5 μg/dL in LMICs, despite leaded petrol phase-outs. Given the toxicity of lead, even at low amounts of exposure, urgent attention is required to control exposures and to expand population-based sampling in countries with no or scant data.
