Phthalate and DINCH metabolites in the urine of Hungarian schoolchildren: Cumulative risk assessment and exposure determinants

Popis výsledku v původním jazyce

A human biomonitoring study was conducted to assess the exposure of Hungarian children aged 8–11 years to ten phthalate esters (PEs) and DINCH between 2017 and 2018. In addition to collecting urine samples from 262 participants, a questionnaire was completed by the parents or legal guardians to identify potential determinants of exposure. The highest geometric mean concentration was observed for MiBP, followed by MBP, cx- MEHP, OH-MEHP and MEP. Three out of the four DINCH metabolites were detected in more than 90% of the samples. The comparison of the urinary concentrations measured in this study with those observed in the DEMOCOPHES study revealed a significant decreasing trend in all PE metabolites investigated in both studies between 2011/2012 and 2017/2018. Different approaches were used to assess the health risks associated with the exposure to PEs and DINCH. Our results highlighted that the hazard index (HI) values were higher than 1 in 17.6% of the children when the human biomonitoring guidance values were applied. In contrast, less than 3% of the children had HI values exceeding 1 when other sources of reference values were used. By applying a safety factor of 10 for the risk assessment, 17.6–91.6% of the children were characterized by HI values higher than 0.1, indicating the need for risk reduction measures. Overall, DnBP, DiBP and DEHP were identified as the main drivers of the mixture risk. Although PEs and DINCH are ubiquitous contaminants, there are still inconsistencies and gaps in our understanding of the determinants of exposure. The results of the multivariate regression analysis showed significant associations between PE or DINCH metabolite concentrations and certain individual characteristics, use of personal care products, home and school environment and food and beverages consumption 24 h prior to sample collection. © 2024 The Authors
