Issue Date: | 2024 | Journal: | Science of the Total Environment | Abstract: | Background: Very little information is available on the population distribution and on sociodemographic predictors of body concentrations of rare earth elements (REE) and other chemicals used in the manufacturing of high-tech devices. Objectives: To analyze the distribution and associated sociodemographic factors of blood concentrations of chemical elements (including some metals, essential trace elements, rare earth elements and other minority elements) in a representative sample of the general population of Barcelona (Spain). Methods: A sample of participants in the Barcelona Health Survey of 2016 (N = 240) were interviewed face-toface, gave blood, and underwent a physical exam. Concentrations of 50 chemical elements were analyzed by ICPMS in whole blood samples. Results: All 50 chemicals studied, including 26 REE and minority elements, were detected. Lead, silver, arsenic, cadmium, mercury, antimony, strontium, thallium and six essential trace elements were detected in more than 70% of the population. The most frequently detected REE and minority elements were europium (62%), thulium (56%), gold (41%), indium (31%), ruthenium (24%), and tantalum (20%). Less affluent occupational social classes had higher percentages of detection of some REE. Median concentrations of silver, arsenic, cadmium and mercury were: 0.091, 3.01, 0.309, and 3.33 ng/mL, respectively. Women had lower median concentrations than men of lead (1.47 vs. 2.04 mu g/dL, respectively), iron and zinc, and higher concentrations of copper and manganese. The influence of sociodemographic characteristics on chemical concentrations differed by sex. Conclusions: While well-known contaminants as lead, mercury, cadmium, or arsenic were detected in the majority of the population, numerous individuals had also detectable concentrations of chemicals as europium, indium, thulium, or gold. Sociodemographic and physical characteristics (sex, age, social class, weight change) influenced concentrations of some chemicals. | URI: | http://hdl.handle.net/10553/128618 | ISSN: | 0048-9697 | DOI: | 10.1016/j.scitotenv.2023.168502 | Source: | Science Of The Total Environment[ISSN 0048-9697],v. 909:168502 (Enero 2024) |
