Abstract

The limitation in the use of lead in Spanish gasoline has induced a resulting decrease in atmospheric lead concentrations, a remarkable reduction in the lead levels of edible vegetables, as well as a marked decrease in the dietary lead intake of the population of Tarragona Province (Catalonia, N.E. Spain). The present study evaluates the impact of such decreases on blood lead values and hair lead concentrations in an adult and children population of that region. A total of 250 adult participants between 16–65 years of age and 252 children were included in the study. Blood and hair samples were subjected to lead analyses by graphite furnace atomic absorption spectrophotometry and inductively coupled plasma spectrometry, respectively. A substantial decline in both, blood lead levels in adults (47.5%) and lead concentrations in children's hair (53%) was observed. During the period 1990–1995, blood lead levels were reduced from 12.0 μg dl⁻¹ to 6.3 μg dl⁻¹, while the hair lead concentrations decreased from 8.8 μg g⁻¹ to 4.1 μg g⁻¹. These decreases were noted for all the subgroups (sex, age and place of residence) examined, and were mainly attributable to the reduced leaded gasoline consumption.

Secular trends in blood lead concentrations of school-age children in Montevideo, Uruguay from 2009 to 2019
2024, Environmental Pollution
Lead exposure continues to be a public health problem globally, yet very few countries perform systematic biomonitoring or surveillance of children's blood lead levels (BLLs). Secular trends in children's BLLs have not been well characterized outside North America and Europe. In 2009–19, we conducted a series of non-representative cross-sectional surveys in Montevideo, Uruguay, enrolling children living in areas of the city with known or suspected lead contamination. Lead was measured with atomic absorption spectrometry on fasting venous blood samples. Of the 856 children representing independent (non-sibling) observations, 759 had BLL measures. Other missing data were imputed. Using linear and logistic regression models, we estimated the covariate-adjusted year to year difference in mean BLL and the likelihood of having BLL ≥5 and BLL ≥3.5 μg/dL. At the start of the study, mean ± SD BLL was 4.8 ± 2.6 μg/dL, and at the end 1.4 ± 1.4 μg/dL. The prevalence of BLL ≥5 and BLL ≥3.5 μg/dL also differed markedly between 2009 and 2019 (30.8% vs. 2.7% and 53.8% vs. 5.8%). Similarly, where 80.8% of children had BLL ≥2 μg/dL in 2011, in 2019 that number was 19.3%. The estimated year to year difference in BLL was ∼0.3 μg/dL. Despite this progress, pediatric lead exposure remains a problem in Montevideo. In years 2015–19, between 19 and 48% of school children had BLL ≥2 μg/dL, a level at which adverse neurobehavioral outcomes continue to be reported in the literature. Continued prevention and risk-reduction efforts are needed in Montevideo, including systematic surveillance of BLLs in all children.
High lead level in the Alps in XIXth century, learning from the analysis of 138 historical hair stands
2022, Chemosphere

For contemporary data, the HLL background ranges from around 0.45 μg g−1 (Varrica et al., 2018) to 2 μg g−1 (Furman and Laleli, 2000), after the strong decrease around 1990–1995 following the introduction of reduced-lead and unleaded gasoline. During this period, mean HLL values fell from 8.8 to 4.1 μg g−1 (Schuhmacher et al., 1996), the latter very close to the HLL background reported by Revich (1994). These observations show that the impact of leaded products (e.g., paints, kitchenware, beverages and cosmetics) might have been as important contamination source around 1870 as that of leaded gasoline at the end of the 20th century.
Analysis of hair is known to provide useful information about environmental and toxic exposures. Very little historical use has been made of this type of investigation. Here we study 138 human hair samples from 19th century in France.
In order to examine the potential association between contamination and historical health impacts, we characterized contamination by 33 elements in a set of hair strands sampled during the last quarter of the 19th century in the Savoy region of France.
After a selected washing step on 138 hair strands conserved at the Museum National d’Histoire Naturelle in Paris (France), we assessed the presence of inorganics by ICP/MS, and lead level was higher than values reported in literature. We then compared concentrations and distributions between women and men, sampling locations and crossing gender and geographical origin.
Hair lead level was high throughout Savoy at the end of the 19th century: significantly higher for people living in towns or industrial valleys, and lower for those of countryside and mountains areas. Environmental and economic changes (industrialization and urbanization with water adduction and leaded paints), living habits (kitchenware, cosmetics, wine, and tobacco), and local features (mines exploitation, railroad development, and industrialized narrow valleys) could be envisaged for explaining the level of lead contamination. In the same period, the two main industrial valleys of Savoy (Maurienne and Tarentaise) had high rates of endemic goiter and cretinism and among the highest hair lead levels. Other lines of evidence will need to be explore to investigate a possible link between historical Pb exposure and goiter in the study area.
Indoor particulate matter and blood heavy metals in housewives: A repeated measured study
2021, Environmental Research
Particulate matter (PM) less than 2.5 μm in diameter and 10 μm (PM₁₀) contains heavy metals, but whether exposure to PM is significantly associated with the burden of heavy metal exposure in the population is unknown. We investigated the association between exposure to PM and blood concentrations of lead (Pb), cadmium (Cd), and mercury (Hg) in Korean housewives.
From July 2017 to January 2020, we recruited 115 housewives in Ulsan, Republic of Korea. After excluding participants with missing information, we finally included 88 Korean housewives in our study. We measured the concentrations of indoor PM using a gravimetric method 24 h before blood sampling and the concentrations of Cd, Pb, and Hg in blood, twice at a 1-year interval. We used a linear mixed effect model to estimate the associations between indoor PM and blood heavy metals.
Exposure to PM₁₀ was significantly associated with blood concentrations of Cd among Korean housewives. A 10 μg/m³ increase of PM₁₀ the previous day was associated with a 2.8% (95% confidence interval (CI) = 1.1%, 4.6%) and a 1.5% (95% CI = −0.1%, 3.1%) increase in blood concentrations of Cd and Pb in the linear mixed effect model, respectively.
There was a significant association between indoor PM exposure and blood Cd concentrations among Korean housewives. This result suggests that the body burden of heavy metals is significantly associated with air pollution.
Blood lead levels of children in urban and suburban areas in China (1997–2015): Temporal and spatial variations and influencing factors
2018, Science of the Total Environment
Blood lead (Pb) poisoning is a worldwide heath problem, especially in developing countries. As the largest developing country in the world, China faces severe health challenges, in particular the threat of blood Pb poisoning. In this study, the temporal trend of Chinese children's blood lead levels (BLLs) and blood lead poisoning incidence (BLPI) (percentage of BLL > 100 μg/L) and its influencing factors were investigated. We collected articles on children's BLLs published from 1997 to 2017 with sampling time from 1997 to 2015 by searching the databases of VIP Medical Information System (VMIS), China National Knowledge Infrastructure (CNKI) and Wanfang Data. After a rigorous investigation, 259 articles with eligible inclusion criteria were reviewed. Meanwhile, the data of Pb concentrations in the soil of 23 cities and the annual mean PM10 (particulate matter < 10 μm) concentrations of 24 provincial cities were collected. The temporal trend of children's BLLs and BLPIs could be divided into three stages: upward trend from 1997 to 2000, downward trend from 2001 to 2013, and upward trend from 2014 to 2015. The decline of BLLs from 2001 was primarily due to the phasing out of leaded gasoline since 2000 in China, while the descending air quality could explain the upward trend of BLLs in the period from 2014 to 2015. The correlation and regression analysis indicated that soil and air were two major pathways of Pb exposure for children in China. Although a noticeable decrease has been shown, the Chinese children's BLLs were still significantly higher than the levels of developed countries. We highly recommended that the critical value of blood Pb poisoning should be lowered to 50 μg/L in China. Guidelines on the prevention and management of blood Pb poisoning are needed in China.
Evaluation of the effect of an environmental management program on exposure to manganese in a mining zone in Mexico
2018, NeuroToxicology
In the state of Hidalgo, Mexico, is found the largest second deposit of Manganese (Mn) in Latin America. Various studies on the sources of emission, exposure, and the effects on the health of children and adults have been conducted utilizing an ecosystem approach. Given the findings of Mn levels in air and the neurocognitive effects, an Environmental Management Program (EMP) was designed and implemented with the purpose of reducing exposure to Mn of the population, including various actions for reducing Mn emissions into the atmosphere.
To evaluate the impact of the EMP on the concentrations of Mn in air, as well as the modification of exposure to Mn in the blood and hair of adult residents of the communities intervened.
A quasi-experimental study was conducted in five rural communities, in which Mn concentrations were evaluated in air and in blood in the years 2002 and 2007, pre-intervention, and in 2013, postintervention. In 2003, the concentration of hair Mn among the communities was evaluated. Measurements were carried out of Particulate Matter (PM) of >10 and 2.5 μm (PM10 and PM2.5), and Mn in PM10 and PM2.5 were measured using proton-induced X-ray emissions (PIXE). The method of Difference in Differences (DID) was applied to estimate the impact of EMP on Mn concentrations in particulate matter via linear regression through multilevel models. To evaluate the effect of Mn concentrations in air over Mn concentrations in blood in both study periods in the mining communities per year (2002 and 2013), a linear regression model for each year was employed.
We estimated that the EMP contributed to reducing the average daily concentrations of Mn in PM10 and PM2.5 by 92 and 85%, respectively. The adjusted model did not show an effect of Mn concentrations in air over Mn concentrations in blood in both study periods.
The results suggest that the measures implemented to reduce Mn emissions in air exerted a significant impact on the reduction of inhaled exposure in adult population.
Blood and urinary levels of metals and metalloids in the general adult population of Northern France: The IMEPOGE study, 2008–2010
2017, International Journal of Hygiene and Environmental Health

However, the blood lead and urinary vanadium levels are lower in our region than in the French national study (Fréry et al., 2010). The lower blood levels could be explained by the decrease in the mean blood lead level of the general population over the course of time, a phenomenon already reported in other biomonitoring studies and linked to the environmental policies (use of unleaded petrol, replacement of lead pipes…) (Becker et al., 2013; Cerná et al., 2012; Muntner et al., 2005; Schuhmacher et al., 1996; Seo et al., 2015). In point of fact the recruitment of the participants was done in 2006–2007 for the French national study and in 2008–2010 for our regional study.
The assessment of human chemical risks related to occupational or environmental exposure to pollutants requires the use of both accurate exposure indicators and reference values. The objective of this study was to evaluate the blood and urinary levels of various metals and metalloids in a sample of adults aged 20–59 years of the general population of Northern France, a formerly heavily industrialised area that retains some industrial activity.
A cross-sectional study was conducted between 2008 and 2010, enrolling 2000 residents of Northern France. The quota method was used to guarantee the representativeness of the participants on a sex, age, social category and smoking status basis, according to the census done by the French National Institute of Statistics and Economic Studies. The levels of 14 metals: aluminium (Al), antimony (Sb), total arsenic (As), beryllium (Be), cadmium (Cd), cobalt (Co), chromium (Cr), mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb), thallium (Tl), vanadium (V) and zinc (Zn) were quantified by ICP-MS in urine and blood samples.
A total of 982 men and 1018 women participated, allowing the analysis of 1992 blood and 1910 urine samples. Some metal(loid)s were detected in over 99% of the blood (Cd, Co, Mn, Ni, Pb) and urine (As, Co, Pb, Zn) samples and the remaining metals in 84–99% of the samples, with the exception of blood V (19%), blood Be (57%) and urine Be (58%). Mean blood levels of Pb and Zn were significantly higher in men, and Mn, Co and Cr in women. In urine, mean Pb, Tl and Sb concentrations were significantly higher in men, and Al and Co in women. Current smokers had significantly higher mean levels of blood Cd and Pb and lower blood Co, Mn and Hg. In urine (adjusted on urinary creatinine), the smokers had higher mean levels of Cd, Pb, V and Zn and lower mean levels of As, Co, and Hg. Overall, the mean urinary levels of most metal(loid)s found in the general population of Northern France were higher than those found in the French national survey for the same period except for urinary V. Mean blood lead level was markedly less than that of the French national population.
This first biomonitoring survey of a large number of metal(loid)s in the general population of Northern France provides useful information on exposure levels to toxic elements and highlights the specificity of the regional environment. These data could be used, in complement to the national human biomonitoring reference values, for the interpretation of biomonitoring results.
