Lead exposure – A proven threat to children’s health, future in Ghana

Lead exposure is emerging as a growing but underreported public health threat in Ghana, with experts warning that its impact on children’s development, education, and long-term productivity could be significant if left unaddressed.

Recent assessments by international health organizations estimate that millions of children in low- and middle-income countries, including Ghana, face elevated blood lead levels.

In Ghana specifically, national surveillance conducted by environmental health group Pure Earth in collaboration with the Ghana Health Service found that 53.5% of 3,227 children tested had blood lead levels above 5 µg/dL, the threshold at which the World Health Organization recommends public health action.

Health experts warn that even low levels of exposure can cause lasting harm. According to UNICEF, lead is “highly toxic,” and even small amounts can cause irreversible brain damage, reduced IQ, and long-term learning difficulties, particularly in children and pregnant women. 

Multiple exposure pathways

Lead exposure in Ghana comes from a range of environmental and household sources. UNICEF identifies informal battery recycling, electronic waste processing, contaminated cookware, cosmetics, and certain traditional products as key pathways. Children living near scrap yards or recycling sites are especially vulnerable. 

In some cases, contamination is found in everyday items. A joint UNICEF and Food and Drugs Authority study detected dangerously high lead levels in traditional eyeliners, baked clay consumed by pregnant women, and even some spices and cereals sampled from markets across multiple regions. 

Environmental exposure also plays a major role. The national blood lead survey found extremely high soil contamination near informal recycling areas, with some locations recording lead levels nearly 18 times higher than international residential safety standards. 

Medical experts emphasize that children absorb far more lead than adults. UNICEF notes that children can absorb four to five times more lead into their bodies, increasing the risk of neurological damage during critical developmental stages. 

Lead poisoning often presents without obvious symptoms, making it difficult to detect. However, long-term exposure has been linked to reduced cognitive development, behavioral challenges, and impaired academic performance. Public health advocates warn that the effects can persist into adulthood, affecting employment opportunities and lifetime earnings.

Beyond individual health, lead exposure has broader national implications. Environmental health organizations warn that lead pollution contributes to school failure, reduced productivity, and increased healthcare costs, ultimately affecting economic growth. 

Globally, the scale of the problem is significant. A landmark analysis by UNICEF and Pure Earth estimates that one in three children worldwide, about 800 million, have blood lead levels requiring intervention, underscoring the magnitude of the public health challenge.

Call for stronger awareness and action

Despite these risks, awareness in many communities remains limited. Experts say many families are unaware of exposure pathways, and symptoms are often mistaken for other conditions. This has prompted calls for stronger public education, improved monitoring, and tighter regulation of lead-containing products.

Health organizations also highlight the role of journalism in bringing attention to the issue. Translating scientific data into accessible reporting, documenting affected communities, and tracking policy responses are seen as critical steps toward elevating lead exposure as a national priority.

Addressing lead exposure, stakeholders say, is both a health and development imperative.

Reducing exposure among children protects learning outcomes, strengthens human capital, and supports sustainable economic growth, making it not only a medical issue but an investment in Ghana’s future.
