    Environmental lead pollution is higher in Greek urban areas than rural ones, affecting adults, children, and neonates. Elevated blood lead levels in children were linked to anemia.

    Area of Science:

    • Environmental Health
    • Toxicology
    • Public Health

    Background:

    • Environmental lead pollution poses a significant public health risk.
    • Blood lead concentration serves as a key indicator of lead exposure.
    • Previous studies have highlighted geographical disparities in lead exposure.

    Purpose of the Study:

    • To assess and compare blood lead concentrations in diverse populations across Greece.
    • To identify differences in lead exposure between urban and rural settings.
    • To investigate the relationship between elevated blood lead levels and health outcomes in children.

    Main Methods:

    • Blood samples were collected from adult, child, and neonatal groups in various Greek regions.
    • Blood lead concentrations were measured using standardized laboratory techniques.

  • Data analysis compared mean blood lead levels and prevalence of undue lead absorption between urban and rural populations.

    • Main Results:

    • Mean blood lead levels were significantly higher in urban individuals (adults: 27.03 µg/100 mL, children: 32.30 µg/100 mL, neonates: 31.03 µg/100 mL) compared to rural individuals (adults: 18.81 µg/100 mL, children: 22.98 µg/100 mL, neonates: 21.66 µg/100 mL).
    • Twenty-one percent of urban dwellers exhibited undue lead absorption (blood lead > 40 µg/100 mL), versus only 1.7% in rural areas.
    • Children identified with elevated blood lead levels also presented with anemia.

    Conclusions:

    • Greek urban environments exhibit substantially higher levels of lead pollution compared to rural areas.
    • A significant portion of the urban population shows signs of excessive lead absorption, a critical public health concern.
    • Childhood anemia is associated with elevated blood lead levels, underscoring the neurodevelopmental risks of lead exposure.
