Area of Science:

Environmental Health
Pediatric Toxicology
Public Health

Background:

Chronic lead exposure in children is a global health issue, yet understudied in Palestine.
Lead poisoning poses risks to neurological development and overall child health.

Purpose of the Study:

To assess blood lead levels (BLLs) in schoolchildren in Nablus, Palestine.
To identify potential risk factors associated with elevated BLLs in this population.

Main Methods:

A cross-sectional survey of 178 children (ages 6-8) from 3 Nablus schools.
Collection of blood samples for lead level analysis.
Gathering of demographic, clinical, and environmental data.

Main Results:

The mean BLL was 3.2 (SD 2.4) microg/dL, with 4.5% of children exceeding 10 microg/dL.
Higher BLLs were observed in children from refugee camps near industrial/high traffic zones.
BLLs showed positive correlation with family size and negative correlation with household area.

Conclusions:

Palestinian schoolchildren exhibit higher BLLs compared to international benchmarks where leaded gasoline is banned.
Socioeconomic factors, including living in refugee camps and economic deprivation, appear to contribute to increased lead exposure.
Urgent public health interventions are needed to address childhood lead exposure in Palestine.
