Summary: Ten years of nationally representative biomonitoring data from the Canadian Health Measures Survey (CHMS) between 2007 and 2017 indicate a decrease in concentrations for many priority chemicals in the Canadian population, such as DEHP, PFOS, PFOA, DMP, lead, and BPA. However, concentrations of two pyrethroid pesticide metabolites are increasing. Continued collection of national biomonitoring data is necessary to monitor exposure trends over time.

Summary: Urine is commonly used in human biomonitoring studies to measure the excretion kinetics of less-persistent contaminants. However, urine samples can show significant variability in the concentrations of phthalate metabolites and bisphenol A depending on the sampling time. This study evaluated within- and between-person variabilities of phthalate metabolites and bisphenol A in spot urine samples collected over seven consecutive days. Results showed that some metabolites had poor intraclass correlation coefficients, indicating a high variability within individuals. Adjusting for creatinine and specific gravity increased the correlation coefficients, suggesting the need for randomly collected spot urine samples. Furthermore, first morning voids were found to be significantly correlated with daily composites, indicating their potential in estimating daily exposure doses. Overall, this study provides insights into the variability of urine concentrations and suggests improved sampling design for biomonitoring studies.

Summary: Bisphenol A (BPA) is an artificial substance produced during the manufacturing of plastics and has become a pervasive concern. The European Union has classified BPA as a substance of great concern. The study estimated the total BPA exposure levels in the general population and found that the high-exposure group did not have a sufficient margin of exposure when compared to toxicological effects. Food is the main source of exposure, but other sources may exist in the high-exposure group. Integrated risk management is necessary to reduce BPA exposure, and a new methodology for human health evaluation of low-dose BPA exposure is needed.

Summary: Environmental exposure to active pharmaceutical ingredients (APIs) can have negative effects on ecosystems and human health. A global-scale study of API pollution in rivers highlights the highest concentrations in sub-Saharan Africa, south Asia, and South America, primarily in low- to middle-income countries with poor wastewater and waste management infrastructure. The most frequently detected APIs include carbamazepine, metformin, and caffeine, with some concentrations exceeding safe levels for aquatic organisms. Pharmaceutical pollution poses a global threat to environmental and human health and has implications for achieving the United Nations Sustainable Development Goals.

Summary: This umbrella review synthesized the findings of selected reviews on the non-carcinogenic health effects of exposure to polycyclic aromatic hydrocarbons (PAHs) in human populations. The review found associations between PAH exposure and adverse health outcomes such as lowered IQ, impaired cognitive development, decreased pulmonary function, hypertension, preterm birth, and delayed fetal growth. However, the associations were inconsistent or null for attention-deficit/hyperactivity disorder, behavioral problems, asthma, and hypertension (only in occupational setting). More research is needed to investigate the effects of PAH exposure on respiratory diseases, cardiovascular diseases, obesity, and infertility. Challenges in exposure assessment were identified, including exposure to mixtures with other chemicals and limited coverage of biomonitoring data.

Summary: This study examined the associations between persistent organic pollutants (POPs) and thyroid hormone levels in humans, and found that these associations are influenced by sex, menopausal status, and age. Different POPs had different effects on different hormones, and the associations varied in different population groups. Furthermore, the study also suggested that thyroxine-binding globulin (TBG) and peripheral deiodinase activity (G(D)) may play important roles in explaining the changes in total T4 and total T3.

Summary: Synthetic musk compounds (SMCs) are widely used in consumer products and their effects on freshwater fish have been rarely investigated. This study found that MK and HHCB can decrease T4 levels and cause hypoactivity in larval zebrafish. HHCB and AHTN could also influence thyroid hormone or behavior of the larval fish at levels observed in the ambient environment. Further studies on the ecological consequences of these SMCs are warranted.

Summary: In this systematic review, the authors examined the presence and potential effects of DINP and DIDP, two plasticizers used as alternatives to DEHP, in various environmental media, foods, consumer products, and human populations. The results indicate that DINP and DIDP are widely present in indoor environments, diets, and children's products. While the levels of DINP exposure were found to be relatively lower compared to DEHP, it still exhibited similar endocrine disruption potentials, particularly among males and pregnant women. There are knowledge gaps regarding the exposure of DIDP in the human population.
