Workshop in Astana on Lead Poisoning of Children in Kazakhstan
The workshop was planned as a continuation of the roundtable discussion in Shymkent (on the 30th of October, 2025) to present the results of studies on lead contamination and the health risks of lead poisoning to national stakeholders and government agencies.
The workshop was organized by the Ministry of Ecology and Natural Resources of the Republic of Kazakhstan and the civil society organization Human Health Institute (HHI). The list of participants included: Kazakhstan State Hydro-Meteo Service, Zhasyl Damu (Green Development), UNICEF, South Kazakhstan Medical Academy, TerraGraphics International Foundation (TIFO) (https://terragraphicsinternational.org/), Environmental Health Project Management Institute (EHPMI), Kyrgyzstan societal association Ekois-Bishkek, Karaganda Science Centre, CSO Kameda, CSO Community Hub, and other organizations.
The workshop was opened by the Ministry of Environment, which invited participants to discuss lead poisoning as a significant environmental health problem in Kazakhstan. Then, UNICEF Kazakhstan presented its work assessing the health risks of children’s exposure to lead. The study found that even in Astana and Almaty, where heavy metal contamination is not particularly high, children have elevated blood lead levels. For example, in Astana, 0.8% of tested children (n=511) had blood lead levels between 10 and 20 μg/dL. The study highlighted the need for more detailed assessments and monitoring of lead-related health risks in Kazakhstan, particularly in industrial cities like Shymkent.
The Human Health Institute and EHPMI shared the results of the study conducted from 2022-2025 in partnership with EHPMI, TIFO, and South Kazakhstan Medical Academy. The results confirm that severe surface soil contamination remains throughout the city. Levels of lead, arsenic, and chromium are well above both Kazakh and US standards, often by orders of magnitude. It is well established that there is no safe level of lead exposure; soil lead levels in Shymkent put children at risk of developmental delays, behavioral problems, learning disabilities, and a lifetime of irreversible health issues ranging from kidney disease to cardiovascular disease. At a population level, this exposure puts Shymkent at risk of lower economic productivity, higher healthcare costs, and measurable reductions in educational achievement compared to other cities in Kazakhstan.
Geospatial analysis showed the highest concentrations near the smelter facility, where soil lead levels exceed 10,000 mg/kg in some areas (compared to the Kazakh standard of 32 mg/kg). Average lead concentrations are 715 mg/kg, with a maximum value reaching 34,600 mg/kg. The Kazakh and US standards for Pb in soils are 32 mg/kg and 100 mg/kg, respectively, indicating results that pose an immediate and severe risk to residents. Regular exposure to these metals is a serious risk to children, who have higher exposures and organ systems that are especially vulnerable to irreversible damage. Because exposures that occur in utero can be especially damaging to the fetus, women of childbearing age are also an important vulnerable group.
In the next presentation, TIFO shared examples of addressing childhood lead poisoning in the USA, Russia, Nigeria, and Kyrgyzstan. Despite the severity of the problem, this is a tractable issue. There are proven methods for addressing lead poisoning that can be adapted and adopted for Shymkent, and it is urgent to begin doing so.
Ekois-Bishkek presented results of a national study of blood lead levels in Kyrgyzstan, conducted by in 2025 by the Ministry of Health of the Kyrgyz Republic, the National Institute of Public Health (NIPH), the Department of Disease Prevention and State Sanitary and Epidemiological Surveillance, and the Republican Center for Health Promotion and Mass Communication, together with international partners Pure Earth, Vital Strategies, and ECOIS-Bishkek. It was the first nationwide assessment of blood lead levels among preschool children aged 13–72 months. The study, conducted across 18 regions, represents the country’s most comprehensive effort to date to assess lead exposure in young children. The study found that elevated blood lead levels are present throughout the country. One in five children (21%) had concentrations above 5 μg/dL, and detectable levels were found in almost half of all participants. The study revealed very low levels of public awareness about the health effects of lead exposure. This study is an important example for Kazakhstan and other countries of the region that presently lack a national program of blood lead monitoring. The experience of Kyrgyzstan can be used for conducting a similar national study in Kazakhstan as the first step in establishing a national lead health risk surveillance system.
The last presentation of the workshop, titled “Assessment of Lead Intoxication in Shymkent Based on Clinical and Experimental Data,” was delivered by a representative of the South Kazakhstan Medical Academy. The presentation showed the results of previous studies of lead health risks in Shymkent conducted in 2011. The study found very high blood lead levels in children and high health risks associated with contaminated dust. It was pointed out that since 2011, there have been no attempts to monitor blood lead levels in Shymkent and address the problem of lead poisoning of children.


The workshop participants discussed the presentations and asked questions about the research methods and the obtained results. It was agreed that a coordinated strategy is necessary to address lead poisoning in Shymkent, implemented at the local level and supported from the national level. There should be a formal coordination mechanism that brings together health, environment, housing, and social services sectors to synchronize efforts across monitoring, prevention, and remediation. There should be a long-term program to remediate contaminated areas, implement medical monitoring and home follow-up, and assess secondary sources of lead exposure. Most importantly, all participants agreed that immediate action is needed to improve the health of children and families in Shymkent.
