Background of the Study:
Lead poisoning remains a significant environmental health hazard, particularly for children, due to its detrimental effects on neurological development. In Katsina State, sources of lead exposure include industrial emissions, contaminated soil, and the use of leaded paints and traditional remedies. Children are especially vulnerable to lead poisoning because their developing nervous systems are more susceptible to the neurotoxic effects of lead, which can result in cognitive impairments, behavioral disorders, and long-term developmental delays (Ibrahim, 2023).
In Katsina State, inadequate regulation of industrial emissions and limited public awareness contribute to high levels of lead exposure in certain communities. Many households and schools are located near industrial areas or old infrastructures where lead-based products are still in use. Studies have indicated that even low levels of lead exposure can have irreversible effects on children’s health, making early detection and intervention critical (Aminu, 2024). Despite efforts by local authorities to reduce lead exposure, the prevalence of lead poisoning in children remains a pressing concern, with potential lifelong implications for educational attainment and economic productivity.
This study aims to assess the extent of lead poisoning among children in Katsina State by measuring blood lead levels and correlating these with environmental exposure indicators. The research will explore the main sources of lead exposure, evaluate the severity of its impact on cognitive and physical development, and identify vulnerable sub-populations. By generating localized data, the study intends to inform public health policies, promote effective lead remediation strategies, and enhance community awareness about the dangers of lead exposure (Zubair, 2025).
Statement of the Problem :
Lead poisoning in Katsina State continues to be a major public health issue, especially among children who are at a critical stage of neurological development. Despite existing regulatory measures, exposure to lead from industrial emissions, contaminated environments, and obsolete lead-containing materials persists, resulting in elevated blood lead levels among children (Sani, 2023). This exposure is linked to significant health consequences including cognitive deficits, behavioral problems, and impaired physical growth. The lack of comprehensive, localized data on lead exposure levels in Katsina State hinders the development of targeted interventions to mitigate its impact.
Children in high-risk areas, particularly those living near industrial zones or in older housing with lead-based paints, are disproportionately affected. The chronic health effects of lead poisoning not only impede educational performance but also predispose these children to long-term socio-economic disadvantages. Moreover, the low level of public awareness about the sources and dangers of lead exposure exacerbates the problem, resulting in delayed detection and intervention. The absence of systematic screening programs and effective community education further compounds the issue, leaving many cases of lead poisoning unrecognized and untreated (Garba, 2024).
This study seeks to systematically assess lead poisoning among children in Katsina State by determining blood lead levels and identifying key environmental exposure pathways. The research aims to provide critical data to support the formulation of robust public health policies and targeted remediation programs, thereby reducing the burden of lead poisoning and protecting the future health and development of Katsina’s children.
Objectives of the Study:
- To measure blood lead levels in children in Katsina State.
- To identify the primary sources of lead exposure affecting children.
- To recommend effective interventions to reduce lead exposure and its health impacts.
Research Questions:
- What are the blood lead level concentrations among children in Katsina State?
- What are the major environmental sources of lead exposure in the region?
- What intervention strategies can effectively reduce lead poisoning in children?
Research Hypotheses:
- H1: Children in areas with higher environmental lead contamination have elevated blood lead levels.
- H2: Exposure to lead-based paints and industrial emissions is significantly associated with cognitive impairments in children.
- H3: Community-based lead remediation programs will significantly reduce blood lead levels among children.
Scope and Limitations of the Study:
This study focuses on children in selected communities in Katsina State, assessing blood lead levels and environmental exposure. Limitations include potential variability in exposure levels and challenges in obtaining representative blood samples.
Definitions of Terms:
- Lead Poisoning: A medical condition caused by elevated levels of lead in the body, leading to neurotoxicity.
- Blood Lead Levels: The concentration of lead in the blood, typically measured in micrograms per deciliter (µg/dL).
- Neurotoxicity: Damage to the nervous system caused by exposure to toxic substances such as lead.
