Human lead (Pb) exposure can result in a number of adverse health outcomes, particularly in children.
An assessment of lead exposure sources was carried out in the Republic of Georgia following a nationally representative survey that found elevated blood lead levels (BLLs) in children.
A range of environmental media were assessed in 25 homes and four bazaars spanning five regions. In total, 682 portable X-Ray Fluorescence measurements were taken, including those from cookware (n = 53); paint (n = 207); soil (n = 91); spices (n = 128); toys (n = 78); and other media (n = 125). In addition, 61 dust wipes and 15 water samples were collected and analyzed.
Exceptionally high lead concentrations were identified in multiple spices. Median lead concentrations in six elevated spices ranged from 4-2,418 times acceptable levels. Median lead concentrations of all other media were within internationally accepted guidelines. The issue appeared to be regional in nature, with western Georgia being the most highly affected. Homes located in Adjara and Guria were 14 times more likely to have lead-adulterated spices than homes in other regions.
Further study is required to determine the source of lead contamination in spices. Policy changes are recommended to mitigate potential health impacts. The results of this study contribute to a growing body of evidence that points to adulterated spices as a significant source of human lead exposure.
人类铅(Pb)暴露会导致许多健康不良后果,尤其是在儿童中。
在全国代表性调查发现儿童血铅水平(BLL)升高后,对格鲁吉亚共和国的铅暴露源进行了评估。
在五个地区的 25 个家庭和四个集市中评估了一系列环境介质。总共进行了 682 次便携式 X 射线荧光测量,包括炊具(n = 53);油漆(n = 207);土壤(n = 91);香料(n = 128);玩具(n = 78);和其他媒体(n = 125)。此外,还收集并分析了 61 个灰尘擦拭物和 15 个水样。
在多种香料中发现了异常高的铅浓度。六种高浓度香料的中位数铅浓度范围为 4-2418 倍可接受水平。所有其他媒体的中位数铅浓度均在国际公认的准则范围内。该问题似乎具有区域性,西部格鲁吉亚受影响最大。位于阿扎尔和古里亚的家庭比其他地区的家庭更有可能食用含铅香料,其可能性是其他地区的 14 倍。
需要进一步研究以确定香料中铅污染的来源。建议政策变更以减轻潜在的健康影响。本研究的结果为越来越多的证据提供了依据,这些证据表明,掺假香料是人类铅暴露的重要来源。
