Usefulness of lead isotopes analysis in a pediatric case of chronic lead poisoning.
Identifying the source of lead is a key measure in the management of childhood lead poisoning. In cases with multiple potential sources or with unusual circumstances, this identification can be complex. By comparing the lead isotopic ratios (IRs) between the potential sources and the blood sample from the patient, it is possible to identify which source caused the poisoning. We report here the case of a 13-years-old girl, screened for lead poisoning as she was known to eat paint chips from two walls in her apartment. Her blood lead level was 395 µg/L, and the environmental investigation came back negative. X-ray fluorescence found lead concentration in paints to be below the regulatory threshold of 1 mg/cm2. As there was no other potential source of lead exposure in this case, a comparative analysis of the IRs of lead between the child's blood and two presumed sources (bathroom and kitchen paints) was performed. This analysis confirmed the source of lead intoxication to be the paints in the apartment, mostly from the bathroom wall.
期刊介绍：
Archives of Environmental & Occupational Health , originally founded in 1919 as the Journal of Industrial Hygiene, and perhaps most well-known as the Archives of Environmental Health, reports, integrates, and consolidates the latest research, both nationally and internationally, from fields germane to environmental health, including epidemiology, toxicology, exposure assessment, modeling and biostatistics, risk science and biochemistry. Publishing new research based on the most rigorous methods and discussion to put this work in perspective for public health, public policy, and sustainability, the Archives addresses such topics of current concern as health significance of chemical exposure, toxic waste, new and old energy technologies, industrial processes, and the environmental causation of disease such as neurotoxicity, birth defects, cancer, and chronic degenerative diseases. For more than 90 years, this noted journal has provided objective documentation of the effects of environmental agents on human and, in some cases, animal populations and information of practical importance on which decisions are based.
