Summary: The study found that in Ufa (Russia), volatile DBPs in drinking water were mainly chlorine-based, while semi-volatile DBPs were predominantly bromine-based. Chlorine dose showed linear correlations with trihalomethane and haloacetic acid formation, but no correlations were observed for halogenated semi-volatile products with water quality parameters or chlorine dose.

Summary: Exposure of pregnant women to endocrine disruptor compounds, such as parabens and bisphenol A, is a concern for fetal development. This study examined the occurrence of these compounds and their degradation products in drinking water samples from a French cohort study. The results showed that parabens, bisphenols, and their degradation products were detected in drinking water, with the highest detection frequencies for monochlorinated degradation products. This analytical approach provides insights into the human chemical exposome.

Summary: This study aimed to investigate the volatile profiles of M. sextelata under three dehydration methods: freeze, hot air, and natural air drying. It was found that comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry was the best choice to differentiate the volatile profiles. Freeze-dried samples had the most abundant volatile compounds, while hot air-drying promoted the production of compounds with roasted flavor and natural air-drying resulted in unpleasant acids releasing.

Summary: Previous studies mainly used gas chromatography-mass spectrometry (GC-MS) to analyze volatile compounds in soy sauce. This study employed both GC-MS and headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS) to qualitatively and quantitatively analyze the volatile compounds in high-salt liquid-state fermentation soy sauce (HLFSS). The results revealed that there were 174 substances detected, with 87 detected by HS-GC-IMS and 127 by GC-MS. Aldehydes, ketones, esters, and alcohols were identified as the major compounds in HLFSS. Additionally, some compounds like ethyl pyruvate, (E)-2-pentenal, and diethyl propanedioate were newly detected using HS-GC-IMS.

Summary: The study found that maternal serum levels of poly- and perfluoroalkyl substances (PFAS) are associated with sex steroid hormone levels during pregnancy. Specifically, PFHxS is associated with increased testosterone levels in male fetuses, while PFNA and PFDA are associated with increased free testosterone levels in male fetuses. For female fetuses, PFHxS is associated with increased levels of estradiol and estriol. No associations were found for PFOS and PFOA.

Summary: This study collected 72 single-use medical products of four categories from a hospital in New York State in 2015 and analyzed their migration of 10 phthalates in an ethanol/water mixture. The results showed that the leached phthalate concentration ranged from 0.04 to 54,600 μg, with DEHP being the major phthalate found in 99% of the samples. DEHP was also found in notable concentrations in products labeled as DEHP-free. The study calculated the direct exposure to phthalates from medical devices and first aid supplies, as well as dermal intake from creams/lotions.

Summary: This study investigated the exposure of infants in South China to neonicotinoid insecticides (NEOs). The results showed that infants had detectable levels of NEOs in urine and blood samples, breast milk, infant formula, and tap water. The concentrations of specific NEOs varied in different samples, with dinotefuran and imidacloprid being the most abundant in urine, blood, breast milk, infant formula, and tap water. Older infants had higher NEO exposure than younger infants. Blood samples had higher concentrations of NEOs compared to urine samples, indicating that NEOs readily enter the bloodstream. Breast-fed infants had higher exposure levels than formula-fed infants. The study also found that external sources contributed to the majority of NEO exposure in infants.

Summary: This study evaluated the toxic potency of PFECHS, an emerging PFAS, on zebrafish embryos and its potential effects in aquatic environments. The results showed that PFECHS caused fewer mortalities than PFOS in both acute and chronic exposures but resulted in a similar incidence of deformities. Exposure to PFECHS also increased the levels of specific genes at concentrations relevant to the environment. These findings provide insights into the safety of emerging PFAS alternatives in the aquatic environment and highlight the potential similarity of effects with legacy PFASs.

Summary: Breast cancer is the most common and deadliest cancer in women worldwide. Tamoxifen is widely prescribed for estrogen-receptor-positive breast cancer and has both anticancer and chemo-preventive effects. This review focuses on the potential importance of vitamin E in breast cancer chemo-prevention and how it can affect the actions of tamoxifen. The findings suggest that individually designed nutritional interventions with vitamin E should be further considered for breast cancer patients.

Summary: Per- and polyfluoroalkyl substances (PFAS) are a group of fluorinated organic compounds widely used in consumer products and industrial applications. The phased-out global use of perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) has led to the replacement of these compounds with shorter-chain PFAAs, which are now widely detected in the environment. This study found high concentrations of ultrashort- and short-chain PFAAs in indoor dust, water, and human samples, highlighting the need for further research on their potential adverse health effects.

Summary: This study analyzed urine samples collected from 12 cities in mainland China to determine the concentrations of volatile organic compounds (VOCs) and oxidative stress biomarkers. The results showed that VOC exposure primarily came from cooking, solvents, and vehicle emissions. Regional variations in VOC concentrations were observed, with higher levels found in North and South China. The study also revealed a positive correlation between most VOCs and oxidative stress markers, suggesting potential health risks associated with VOC exposure.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
