Abstract
Background-aim: Children represent a particularly susceptible population to endocrine-disrupting chemical (EDC) exposure; however, biomonitoring data in this population remain limited. To the best of our knowledge, this is the first study using hair biomonitoring to simultaneously assess the concentrations of phthalate metabolites (PMs), triclosan (TCS) and triclocarban (TCC) in children with obesity (OB), type 1 diabetes mellitus (T1D), and hypothalamic-pituitary-related diseases (HPRD), through hair biomonitoring.
Methods: Liquid chromatography-mass spectrometry (LC-MS) was used to measure TCS, TCC and PM levels in head hair samples from 212 children, categorized into control, T1D, HPRD and OB groups. PMs and TCS levels were compared across groups and evaluated in relation to health issues, cosmetics exposure, dietary habits, cardiometabolic, and somatometric parameters.
Results: Our hair biomonitoring results showed that the most commonly detected EDCs were MEHP, MBP, MiBP, and TCS, with detection frequencies of samples 95.3%, 84.4%, 79.7%, and 60.8%, respectively. Children with T1D had statistically significantly higher mean MEHP concentrations than the control group. Children with HPRD exhibited higher PM concentrations, primarily driven by elevated mean MEHP and MBP levels compared with the control group. In contrast, mean MiBP levels were lower in the OB group than in the control group. Regarding TCS levels, no statistically significant differences were observed across the disease groups compared with controls. TCS was inversely associated with somatometric parameters in the OB group. Subgroup analyses by age, sex, residence area, and maternal education were conducted to assess statistically significant differences in concentrations of PM and TCS.
Conclusions: Overall, our biomonitoring results indicate group-specific concentration patterns of PMs and TCS among children with T1D, HPRD and OB groups compared to the control group. In particular, PM levels were higher in children with T1D and HPRD and lower in those with OB groups compared to the control group. As a result, this is the first study to assess PM and TCS concentrations in children across clinical groups, using hair matrix.
期刊介绍：
The Journal of Xenobiotics publishes original studies concerning the beneficial (pharmacology) and detrimental effects (toxicology) of xenobiotics in all organisms. A xenobiotic (“stranger to life”) is defined as a chemical that is not usually found at significant concentrations or expected to reside for long periods in organisms. In addition to man-made chemicals, natural products could also be of interest if they have potent biological properties, special medicinal properties or that a given organism is at risk of exposure in the environment. Topics dealing with abiotic- and biotic-based transformations in various media (xenobiochemistry) and environmental toxicology are also of interest. Areas of interests include the identification of key physical and chemical properties of molecules that predict biological effects and persistence in the environment; the molecular mode of action of xenobiotics; biochemical and physiological interactions leading to change in organism health; pathophysiological interactions of natural and synthetic chemicals; development of biochemical indicators including new “-omics” approaches to identify biomarkers of exposure or effects for xenobiotics.
