Blood lead levels in preschool children in Rawalpindi
Insights
Over 90% of preschool children in Rawalpindi have elevated blood lead levels, exceeding safe limits. Common environmental exposures like leaded petrol and contaminated surma contribute to this public health concern.
Area of Science:
- Environmental Health
- Pediatric Toxicology
- Public Health
Background:
- Elevated blood lead levels (BLLs) pose significant health risks to children.
- Urban environments can harbor various sources of lead exposure.
- Preschool-aged children are particularly vulnerable to lead's neurotoxic effects.
Purpose of the Study:
- To determine the blood lead levels in preschool children living in urban Rawalpindi.
- To identify potential sources and trends of lead exposure in the study population.
Main Methods:
- Blood samples were collected from 92 preschool children (aged 1-5 years) in urban Rawalpindi.
- Blood lead levels were quantified using standard laboratory methods.
- Demographic data and potential exposure sources were considered.
Main Results:
- Blood lead levels ranged from 7 to 34 µg/dL, with a mean of 18.8 µg/dL.
- Over 90% of children exceeded the acceptable BLL of 10 µg/dL.
- Mean BLLs were higher in males (20.3 µg/dL) than females (17.2 µg/dL).
Conclusions:
- Preschool children in urban Rawalpindi exhibit alarmingly high blood lead levels.
- Widespread exposure sources including leaded petrol, contaminated surma, and leaded paints are likely contributors.
- Urgent public health interventions are necessary to mitigate lead exposure and protect child health.
Abstract:
Blood lead levels were determined in preschool children residing in Urban areas of Rawalpindi city. Of 92 (50 males and 42 females) children aged one to 5 years were included in the study. Blood lead levels ranged from 7 micrograms/dl to 34 micrograms/dl (mean 18.8 micrograms/dl). The mean lead levels were slightly higher in males (20.3 micrograms/dl) than in females (17.2 micrograms/dl) and over 90% children had lead levels above the acceptable limit of 10 micrograms/dl. Use of leaded petrol, contaminated surma, leaded paints and pica in children are common in our country and may lead to increased lead levels and appropriate measures should be taken to control this trend.
