Environmentally relevant concentrations of benzophenones exposure disrupt intestinal homeostasis, impair the intestinal barrier, and induce inflammation in mice. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2024; 350:123948. [PMID: 38614423 DOI: 10.1016/j.envpol.2024.123948] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Revised: 03/28/2024] [Accepted: 04/08/2024] [Indexed: 04/15/2024]
Abstract
The aim of this study is to investigate the adverse effects of benzophenones (BPs) on the intestinal tract of mice and the potential mechanism. F1-generation ICR mice were exposed to BPs (benzophenone-1, benzophenone-2, and benzophenone-3) by breastfeeding from birth until weaning, and by drinking water after weaning until maturity. The offspring mice were executed on postnatal day 56, then their distal colons were sampled. AB-PAS staining, HE staining, immunofluorescence, Transmission Electron Microscope, immunohistochemistry, Western Blot and RT-qPCR were used to study the effects of BPs exposure on the colonic tissues of offspring mice. The results showed that colonic microvilli appeared significantly deficient in the high-dose group, and the expression of tight junction markers Zo-1 and Occludin was significantly down-regulated and the number of goblet cells and secretions were reduced in all dose groups, and the expression of secretory cell markers MUC2 and KI67 were decreased, as well as the expression of intestinal stem cell markers Lgr5 and Bmi1, suggesting that BPs exposure caused disruption of intestinal barrier and imbalance in the composition of the intestinal stem cell pool. Besides, the expression of cellular inflammatory factors such as macrophage marker F4/80 and tumor necrosis factor TNF-α was elevated in the colonic tissues of all dose groups, and the inflammatory infiltration was observed, which means the exposure of BPs caused inflammatory effects in the intestinal tract of F1-generation mice. In addition, the contents of Notch/Wnt signaling pathway-related genes, such as Dll-4, Notch1, Hes1, Ctnnb1and Sfrp2 were significantly decreased in each high-dose group (P < 0.05), suggesting that BPs may inhibit the regulation of Notch/Wnt signaling pathway. In conclusion, exposure to BPs was able to imbalance colonic homeostasis, disrupt the intestinal barrier, and trigger inflammation in the offspring mice, which might be realized through interfering with the Notch/Wnt signaling pathway.

Abstract
Benzophenone derivatives such as benzophenone-2 (BP-2) belong to the group of endocrine disrupting compounds (EDCs). Increased exposure to EDCs is considered to be an important factor behind the decline of human fertility. The main aim of the present study was to determine the effect of BP-2 on testicular function specified by sperm analysis, the level of sex hormones and their receptors. Since BP-2 has been shown to activate the immune system, another aim of the research was to verify the hypothesis that the immune system may be contributing to the testis toxicity of this compound and for this purpose changes in macrophage and lymphocyte populations in the testes were determined. BP-2 at a dose of 100 mg/kg was administered dermally, twice daily at a dose of 100 mg/kg for 4-weeks. It was shown that BP-2 reduced the number and motility of sperm and increased the number of sperm showing morphological changes. By determining the concentration of sex hormones, a significant decrease in testosterone levels and an increase in the blood levels of 17β-estradiol were demonstrated. Similar to the results obtained from the blood samples, testosterone levels in the testes were lowered, which could affect sperm parameters. The effect of BP-2 on lowering testosterone levels and the number of sperm cells may be due to immunoactivation in the testes, because it has been detected that this compound significantly decreased the number of the immunosuppressive resident testicular macrophages (TMs) (CD68-CD163+), but increased pro-inflammatory TMs with monocyte-like properties (CD68+CD163-).

Abstract
Organic UV filters are ubiquitous as they are used in numerous personal care products. Consequently, people constantly come into direct or indirect contact with these chemicals. Albeit studies of the effects of UV filters on human health have been undertaken, their toxicological profiles are not complete. In this work, we investigated the immunomodulatory properties of eight UV filters representing different chemotypes, including benzophenone-1, benzophenone-3, ethylhexyl methoxycinnamate, octyldimethyl-para-aminobenzoic acid, octyl salate, butylmethoxydibenzoylmethane, 3-benzylidenecamphor, and 2,4-di-tert-butyl-6-(5-chlorobenzotriazol-2-yl)phenol. We demonstrated that none of these UV filters were cytotoxic to THP-1 cells at concentrations up to 50 μM. Importantly, our study highlighted the capacity of nontoxic concentrations of avobenzone and 3-benzylidene camphor to increase the secretion of interleukin 8 (IL-8) from both THP-1 cells and THP-1 derived macrophages. Further, they also exhibited a pronounced decrease of IL-6 and IL-10 release from lipopolysaccharide-stimulated peripheral blood mononuclear cells. The observed immune cell alterations suggest that exposure to 3-BC and BMDM could be involved in immune deregulation. Our research thus provided additional insight into UV filter safety profile.

Abstract
The everyday use of household and personal care products (HPCPs) generates an enormous amount of chemicals, of which several groups warrant additional attention, including: (i) parabens, which are widely used as preservatives; (ii) bisphenols, which are used in the manufacture of plastics; (iii) UV filters, which are essential components of many cosmetic products; and (iv) alkylphenol ethoxylates, which are used extensively as non-ionic surfactants. These chemicals are released continuously into the environment, thus contaminating soil, water, plants and animals. Wastewater treatment and water disinfection procedures can convert these chemicals into halogenated transformation products, which end up in the environment and pose a potential threat to humans and wildlife. Indeed, while certain parent HPCP ingredients have been confirmed as endocrine disruptors, less is known about the endocrine activities of their halogenated derivatives. The aim of this review is first to examine the sources and occurrence of halogenated transformation products in the environment, and second to compare their endocrine-disrupting properties to those of their parent compounds (i.e., parabens, bisphenols, UV filters, alkylphenol ethoxylates). Albeit previous reports have focused individually on selected classes of such substances, none have considered the problem of their halogenated transformation products. This review therefore summarizes the available research on these halogenated compounds, highlights the potential exposure pathways, and underlines the existing knowledge gaps within their toxicological profiles.

Sunscreens: UV filters to protect us: Part 2-Increasing awareness of UV filters and their potential toxicities to us and our environment. Int J Womens Dermatol 2021; 7:45-69. [PMID: 33537395 PMCID: PMC7838327 DOI: 10.1016/j.ijwd.2020.08.008] [Citation(s) in RCA: 41] [Impact Index Per Article: 13.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2020] [Revised: 08/16/2020] [Accepted: 08/18/2020] [Indexed: 01/03/2023] Open
Abstract
BACKGROUND Sunscreens are topical preparations containing one or more compounds that filter, block, reflect, scatter, or absorb ultraviolet (UV) light. Part 2 of this review focuses on the environmental, ecological effects and human toxicities that have been attributed to UV filters. METHODS Literature review using NIH databases (eg, PubMed and Medline), FDA and EPA databases, Google Scholar, the Federal Register, and the Code of Federal Regulations (CFR). LIMITATIONS This was a retrospective literature review that involved many different types of studies across a variety of species. Comparison between reports is limited by variations in methodology and criteria for toxicity. CONCLUSIONS In vivo and in vitro studies on the environmental and biological effects of UV filters show a wide array of unanticipated adverse effects on the environment and exposed organisms. Coral bleaching receives considerable attention from the lay press, but the scientific literature identifies potential toxicities of endocrine, neurologic, neoplastic and developmental pathways. These effects harm a vast array of aquatic and marine biota, while almost no data supports human toxicity at currently used quantities (with the exception of contact allergy). Much of these data are from experimental studies or field observations; more controlled environmental studies and long-term human use data are limited. Several jurisdictions have prohibited specific UV filters, but this does not adequately address the dichotomy of the benefits of photoprotection vs lack of eco-friendly, safe, and FDA-approved alternatives.

Abstract
2-Hydroxy-4-methoxybenzophenone (2H4MBP) is approved by the U.S. Food and Drug Administration for use in sunscreens and other personal products in concentrations of up to 6% either alone or in combination formulations and as an indirect food additive in acrylic and modified acrylic plastics that come into contact with food. 2H4MBP was nominated to the National Toxicology Program by the National Cancer Institute due to widespread exposure via sunscreen use and lack of carcinogenicity data. 2H4MBP was also nominated by a private individual to ascertain genotoxic potential. Male and female Sprague Dawley (Hsd:Sprague Dawley SD) rats (after weaning) and B6C3F1/N mice were exposed to 2H4MBP (greater than 99% pure) in feed for 2 years. Perinatal studies and 14-week interim evaluations were also conducted in rats. Genetic toxicology studies were conducted in Salmonella typhimurium and Escherichia coli. (Abstract Abridged).

Abstract
The present study sought to determine bioaccumulation and potential molecular effects of four of the most environmentally significant sunscreen agents in juvenile loggerhead sea turtles (Caretta caretta) from the Italian coasts of the central Adriatic Sea. Each of these sunscreen agents were found in most of the plasma samples analyzed, with benzophenone-3 as the dominant species. Total concentrations of the sunscreen agents ranged from not detected (<LOD) to 28.43 μg mL-1. Almost all of the gene biomarkers of inflammation, oxidative stress and hormonal activity assessed by RT-qPCR in blood tissue showed significant positive correlations with total sunscreen agent concentrations. The present study is the first to provide data on contamination by sunscreen agents in loggerheads, and indicates that these chemicals tend to bioaccumulate and exert potential adverse effects in sea turtles.

Abstract
Benzophenone-3 (BP-3), the most widely used UV chemical filter, is absorbed well through the skin and gastrointestinal tract and can affect some body functions, including the survival of nerve cells. Previously, we showed that BP-3 evoked a neurotoxic effect in male rats, but since the effects of this compound are known to depend on gender, the aim of the present study was to show the concentration and potential neurotoxic action of this compound in the female rat brain. BP-3 was administered dermally to female rats during pregnancy, and then in the 7th and 8th weeks of age to their female offspring. The effect of BP-3 exposure on short-term and spatial memory, its concentrations in blood, the liver, the frontal cortex, and the hippocampus, and the effect on selected markers of brain damage were determined. Also, the impact of BP-3 on sex and thyroid hormone levels in blood and hematological parameters was examined. It has been found that this compound was present in blood and brain structures in females at a lower concentration than in males. BP-3 in both examined brain structures increased extracellular glutamate concentration and enhanced lipid peroxidation, but did not induce the apoptotic process. The tested compound also evoked hyperthyroidism and decreased the blood progesterone level and the number of erythrocytes. The presented data indicated that, after the same exposure to BP-3, this compound was at a lower concentration in the female brain than in that of the males. Although BP-3 did not induce apoptosis in the hippocampus and frontal cortex, the increased extracellular glutamate concentration and lipid peroxidation, as well as impaired spatial memory, suggested that this compound also had adverse effects in the female brain yet was weaker than in males. In contrast to the weaker effects of the BP-3 on females than the brain of males, this compound affected the endocrine system and evoked a disturbance in hematological parameters more strongly than in male rats.
