Abstract
This study investigated the toxic effects of low-dose hexavalent chromium (Cr(VI)) on rat liver. Male specific pathogen-free (SPF) Sprague-Dawley (SD) rats (4-5 weeks of age) were randomly divided into groups: saline, 0.05 mg/kg Cr(VI), and 0.25 mg/kg Cr(VI). The rats were subjected to intratracheal instillation of K2Cr2O7 suspensions or saline once weekly, for a total of five times. The results showed that the accumulation of Cr(VI) in the blood of the 0.25 mg/kg K2Cr2O7 group was significantly higher than that in the saline group. Transmission electron microscopy (TEM) showed that exposure to hexavalent chromium caused endoplasmic reticulum (ER) oedema and a disordered arrangement. The levels of endoplasmic reticulum stress (ERS)-related proteins (ATF6, P-PERK, P-IRE1, Grp78, and CHOP) in the 0.25 mg/kg K2Cr2O7 group were significantly higher than those in the saline group. The expression of apoptosis-inhibitory protein Bcl-2 was significantly lower in the 0.25 mg/kg K2Cr2O7 group than that in the saline group, and the expression of apoptosis protein Bax was significantly higher in the 0.25 mg/kg K2Cr2O7 group than that in the saline group, indicating that Cr(VI) increased apoptosis. These findings revealed that Cr(VI) may be involved in rat liver injury by initiating ERS-mediated apoptosis. The expression of ATF6, P-PERK, P-IRE1, and Bax in the 0.05 mg/kg K2Cr2O7 group was not significantly different from that in the saline group, and the different effects produced by the two different dose groups provide a possible experimental basis for further study of occupational exposure limits.

PFASs: What can we learn from the European Human Biomonitoring Initiative HBM4EU. Int J Hyg Environ Health 2023; 250:114168. [PMID: 37068413 DOI: 10.1016/j.ijheh.2023.114168] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2022] [Revised: 04/06/2023] [Accepted: 04/11/2023] [Indexed: 04/19/2023]
Abstract
Per- and polyfluoroalkyl substances (PFASs) were one of the priority substance groups selected which have been investigated under the ambitious European Joint programme HBM4EU (2017-2022). In order to answer policy relevant questions concerning exposure and health effects of PFASs in Europe several activities were developed under HBM4EU namely i) synthesis of HBM data generated in Europe prior to HBM4EU by developing new platforms, ii) development of a Quality Assurance/Quality Control Program covering 12 biomarkers of PFASs, iii) aligned and harmonized human biomonitoring studies of PFASs. In addition, some cohort studies (on mother-child exposure, occupational exposure to hexavalent chromium) were initiated, and literature researches on risk assessment of mixtures of PFAS, health effects and effect biomarkers were performed. The HBM4EU Aligned Studies have generated internal exposure reference levels for 12 PFASs in 1957 European teenagers aged 12-18 years. The results showed that serum levels of 14.3% of the teenagers exceeded 6.9 μg/L PFASs, which corresponds to the EFSA guideline value for a tolerable weekly intake (TWI) of 4.4 ng/kg for some of the investigated PFASs (PFOA, PFOS, PFNA and PFHxS). In Northern and Western Europe, 24% of teenagers exceeded this level. The most relevant sources of exposure identified were drinking water and some foods (fish, eggs, offal and locally produced foods). HBM4EU occupational studies also revealed very high levels of PFASs exposure in workers (P95: 192 μg/L in chrome plating facilities), highlighting the importance of monitoring PFASs exposure in specific workplaces. In addition, environmental contaminated hotspots causing high exposure to the population were identified. In conclusion, the frequent and high PFASs exposure evidenced by HBM4EU strongly suggests the need to take all possible measures to prevent further contamination of the European population, in addition to adopting remediation measures in hotspot areas, to protect human health and the environment. HBM4EU findings also support the restriction of the whole group of PFASs. Further, research and definition for additional toxicological dose-effect relationship values for more PFASs compounds is needed.

Abstract
Human biomonitoring (HBM) studies have highlighted widespread daily exposure to environmental chemicals. Some of these are suspected to contribute to adverse health outcomes such as reproductive, neurological, and metabolic disorders, among other developmental and chronic impairments. One of the objectives of the H2020 European Human Biomonitoring Initiative (HBM4EU) was the development of informative effect biomarkers for application in a more systematic and harmonized way in large-scale European HBM studies. The inclusion of effect biomarkers would complement exposure data with mechanistically-based information on early and late adverse effects. For this purpose, a stepwise strategy was developed to identify and implement a panel of validated effect biomarkers in European HBM studies. This work offers an overview of the complete procedure followed, from comprehensive literature search strategies, selection of criteria for effect biomarkers and their classification and prioritization, based on toxicological data and adverse outcomes, to pilot studies for their analytical, physiological, and epidemiological validation. We present the example of one study that demonstrated the mediating role of the effect biomarker status of brain-derived neurotrophic factor BDNF in the longitudinal association between infant bisphenol A (BPA) exposure and behavioral function in adolescence. A panel of effect biomarkers has been implemented in the HBM4EU Aligned Studies as main outcomes, including traditional oxidative stress, reproductive, and thyroid hormone biomarkers. Novel biomarkers of effect, such as DNA methylation status of BDNF and kisspeptin (KISS) genes were also evaluated as molecular markers of neurological and reproductive health, respectively. A panel of effect biomarkers has also been applied in HBM4EU occupational studies, such as micronucleus analysis in lymphocytes and reticulocytes, whole blood comet assay, and malondialdehyde, 8-oxo-2'-deoxyguanosine and untargeted metabolomic profile in urine, to investigate, for example, biological changes in response to hexavalent chromium Cr(VI) exposure. The use of effect biomarkers in HBM4EU has demonstrated their ability to detect early biological effects of chemical exposure and to identify subgroups that are at higher risk. The roadmap developed in HBM4EU confirms the utility of effect biomarkers, and support one of the main objectives of HBM research, which is to link exposure biomarkers to mechanistically validated effect and susceptibility biomarkers in order to better understand the public health implications of human exposure to environmental chemicals.
