Abstract
BACKGROUND There is a lack of research on the relationship between water fluoridation and pregnancy outcomes. OBJECTIVES We assessed whether hypothetical interventions to reduce fluoride levels would improve birth outcomes in California. METHODS We linked California birth records from 2000 to 2018 to annual average fluoride levels by community water system. Fluoride levels were collected from consumer confidence reports using publicly available data and public record requests. We estimated the effects of a hypothetical intervention reducing water fluoride levels to 0.7 ppm (the current level recommended by the US Department of Health and Human Services) and 0.5 ppm (below the current recommendation) on birth weight, birth-weight-for-gestational age z-scores, gestational age, preterm birth, small-for-gestational age, large-for-gestational age, and macrosomia using linear regression with natural cubic splines and G-computation. Inference was calculated using a clustered bootstrap with Wald-type confidence intervals. We evaluated race/ethnicity, health insurance type, fetal sex, and arsenic levels as potential effect modifiers. RESULTS Fluoride levels ranged from 0 to 2.5 ppm , with a median of 0.51 ppm . There was a small negative association on birth weight with the hypothetical intervention to reduce fluoride levels to 0.7 ppm [- 2.2 g ; 95% confidence interval (CI): - 4.4 , 0.0] and to 0.5 ppm (- 5.8 g ; 95% CI: - 10.0 , - 1.6 ). There were small negative associations with birth-weight-for-gestational-age z-scores for both hypothetical interventions (0.7 ppm : - 0.004 ; 95% CI: - 0.007 , 0.000 and 0.5 ppm : - 0.006 ; 95% CI: - 0.013 , 0.000). We also observed small negative associations for risk of large-for-gestational age for both the hypothetical interventions to 0.7 ppm [risk difference ( RD ) = - 0.001 ; 95% CI: - 0.002 , 0.000 and 0.5 ppm (- 0.001 ; 95% CI: - 0.003 , 0.000)]. We did not observe any associations with preterm birth or with being small for gestational age for either hypothetical intervention. We did not observe any associations with risk of preterm birth or small-for-gestational age for either hypothetical intervention. CONCLUSION We estimated that a reduction in water fluoride levels would modestly decrease birth weight and birth-weight-for-gestational-age z-scores in California. https://doi.org/10.1289/EHP13732.

Effect of exposures to multiple metals on blood pressure and hypertension in the elderly: a community-based study. Biometals 2024; 37:211-222.

Abstract
A chronic disease, hypertension (HTN) is prevalent among the elderly. Exploring the factors that influence HTN and blood pressure (BP) changes is of great public health significance. However, mixed exposure to multiple serum metals has had less research on the effects on BP and HTN for the elderly. From April to August 2019, 2372 people participated in the community physical examination program for the elderly in Tongling City, Anhui Province. We measured BP and serum levels of 10 metals and collected basic demographic information. We analyzed the relationship between metal levels and changes in BP and HTN by the least absolute shrinkage and selection operator regression, Bayesian kernel machine regression model, and generalized linear model. In multiple models, lead (Pb) and cadmium (Cd) were still significantly associated with HTN occurrence after adjusting for potential confounders (Pb: ORquartile 4 VS quartile 1 = 1.20, 95% CI 1.01-1.43; Cd: ORquartile 4 VS quartile 1 = 1.37, 95% CI 1.16-1.62). In the male subgroup, results were similar to those of the general population. In the female group, Cd was positively correlated with HTN and systolic blood pressure, while Pb was not. According to this study, Pb and Cd were correlated with BP and HTN positively, and there was a certain joint effect. To some extent, our findings provide clues for the prevention of hypertension in the elderly.

Abstract
Togo's phosphate processing plant at Kpeme discharges waste, containing Cd, Pb, and fluoride, into the sea and on the soil. Heavy metals toxicity on kidneys and the liver has been studied. However, fluoride toxicity on these organs remains to be investigated. The present study deals with the variation in renal and hepatic functioning parameters due to fluoride, Cd and Pb. Totally, 350 volunteers were recruited from five different localities around this phosphate processing plant for sample collection. Cd and Pb contents in blood samples were determined by spectrophotometry and fluoride by the titanium chloride method. Biochemical parameters were measured using Biolab kits. The pollutant contents were elevated in polluted areas where ASAT, ALAT, creatinine, and urea increased, and total protein decreased. Correlation and multivariate tests showed that fluoride is related to the various pathologies mentioned. PCA revealed that phosphate processing in Togo is a source of renal and hepatic toxicity.

Abstract
Arsenic, cadmium, copper, lead, and zinc concentrations in the edible part of wild and farmed Sparus aurata from Algerian coastal were determined. The highest concentrations of cadmium (0.0078 mg kg-1 wet weight), copper (0.98 mg kg-1 w.w), and zinc (5.1 mg kg-1 w.w) were recorded in farmed sea bream, whereas the highest arsenic (5.02 mg kg-1 w.w) and lead (0.006 mg kg-1 w.w) levels were registered in wild one. The statistical analysis (Friedman test, p < 0.05) indicated that the origin of fish (wild, farmed in a cage, and farmed in raceway) has relevance to the distribution of metal. Estimated weekly intake of inorganic arsenic, cadmium, and lead for a 72.5-kg person consuming Sparus aurata from Algeria does not exceed 1% of the WHO/JECFA recommended rate for all metals, certainly due to the limited consumption of seafood products by the local population. The total target hazard index is far less than "one" 1, and the carcinogenic risk for arsenic exceeds the acceptable value of 10-5. Based on the result of this study, the potential risk to human health from the consumption of contaminate farmed sea bream (in the cage) should be considered.

Abstract
Fluoride exposure may cause changes in blood pressure, but this conclusion is controversial. Therefore, this meta-analysis aims to investigate the potential relationship between fluoride exposure and blood pressure or hypertension. PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), WANFANG MED ONLINE, and Chinese Scientific Journals Full-Text Databases (VIP) were searched; in addition, two related studies were added manually. In total, 7 observational studies were identified, the pooled odds ratios (ORs) for hypertension between high and reference fluoride exposure groups were calculated, and the pooled standardized weighted mean difference (SMD) of systolic blood pressure (SBP) and diastolic blood pressure (DBP) was estimated using an inverse-variance weighted random-effects model; next, sensitivity analysis and subgroup analysis were used to assess potential sources of heterogeneity; furthermore, publication bias was assessed using the Begg and Egger test. In brief, there were no statistical differences between exposure groups and control groups in terms of blood pressure or hypertension when all included studies considered. However, subgroup analysis indicated that blood pressure will rise with the increase of fluoride exposure concentrations in endemic fluorosis areas. The corresponding pooled SMD estimates were 0.31 (95% CI 0.11, 0.51) and 0.27 (95% CI 0.11, 0.43) for SBP and DBP. Funnel plots suggested no asymmetry. Our findings support the possibility of a positive correlation between fluoride exposure and blood pressure in endemic fluorosis areas. Additional evidence is needed to assess the dose-response relationship between fluoride exposure and blood pressure.

Abstract
The cadmium (Cd) is a toxic heavy metal that induces oxidative stress in both humans and animals. The plant phenolic compounds are capable of alleviating the toxicity of heavy metals. The encapsulation of plant bioactive compounds using nanoemulsion technology could enhance their bioefficacy. In this study, the protective effects of Anethum graveolens seed's oil nanoemulsion (AGN) against cadmium-induced oxidative stress in mice were studied. The results showed that the major bioactive compounds of essential oil were carvone and limonene. The result of particle size analysis revealed the pseudo-spherical droplets with nanometer size (148.8 ± 9.48 nm), homogenous dispersion, and physical colloidal stability. The Cd intoxication in mice (5 mg/kg BW for 30 days) reduced the body weight gain; however, treatment of the mice with different concentration of AGN (0.125, 0.25, and 0.5 mg/L, 30 days) through drinking water improved the body weight loss, liver Cd deposition, lipid peroxidation, cellular antioxidant redox potential, and inflammation in the liver, kidney, and brain of the mice challenged by cadmium-induced oxidative stress. The results of the present study revealed that drinking the essential oil of Anethum graveolens nanoemulsion containing carvone and limonene could be a promising strategy to protect the tissues against cadmium-induced oxidative damage.

Abstract
Fluoride has been considered as a risk factor of cardiovascular disease due to its endothelial toxicology. However, the mechanism underlying the endothelial toxicity of fluoride has not been clearly illustrated. MiR-200c-3p was strongly linked with endothelial function and its level is increased in serum of fluorosis patients, but it is unclear the role of miR-200c-3p in the fluoride induced endothelial dysfunction. In this study, we confirmed that fluoride exposure induced the apoptosis of endothelial cells both in established rats model and cultured human umbilical vein endothelial cells (HUVECs). And miR-200c-3p was found to be upregulated in NaF treated HUVECs. Fluoride stimulation increased caspase-dependent apoptosis through miR-200c-3p upregulation, with repressing expression of its target gene Fas-associated phosphatase 1 (Fap-1), which functioned as Fas inhibitor. This resulted in activation of Fas-associated extrinsic apoptosis via interaction with increased Fas, Fadd, Cleaved Caspase-8 and Cleaved Caspase-3. The activation of Fas-associated extrinsic apoptosis was abrogated by miR-200c-3p inhibitor. Furthermore, the antiapoptotic effect of downregulated miR-200c-3p was restored by Fap-1 siRNA. These results suggested a determinant role of the miR-200c-3p/Fap-1 axis in fluoride induced endothelial apoptosis.

Abstract
Metal exposure has recently been related to the risk of hypertension. However, the association remains unclear and relevant epidemiologic studies are limited. The present study aimed to assess the associations between exposure to metals and the odds of hypertension, as well as blood pressure (BP) levels. A total of 816 participants were enrolled in southwestern China. Hypertension was defined as a systolic BP (SBP) of ≥140 mmHg or diastolic BP (DBP) of ≥90 mmHg, a self-reported physician diagnosis, or current use of antihypertensive medication. Blood samples were used to detect the levels of exposure to metals, ie, magnesium (Mg), calcium (Ca), iron (Fe), zinc (Zn), arsenic (As), cadmium (Cd), copper (Cu) and lead (Pb). Logistic and linear regression models were used to assess the potential associations. The results show that positive trends for elevated odds of hypertension with increasing quartiles of Fe in a polluted area; and of Mg, Ca and Cu in an unpolluted area. Compared with those in the lowest quartiles, participants in the highest quartiles of Fe, Mg and Ca had 2.7-, 9.0- and 5.1-fold increased odds of hypertension, respectively. High blood Fe and Pb levels in the Cd-polluted area, and Mg and Fe in the unpolluted area were found to be related to increasing SBP and DBP levels. Our findings suggest that exposure to Fe and/or Pb in the polluted area; and Mg, Ca and Fe in the unpolluted area might increase the risk of hypertension or elevate BP levels.
