“…All these changes leading to a reduction in organs weights, we're in agreement with the results of the Kumar et al (12) and contradicted with the result of the Chioca et al (13) who mentioned that NaF doesn't alter the weights of organs and body weights. The ovary is an significant organ of numerous reproductive toxicants and female rats reproductive functions that exposed to NaF was markedly decrease and destroy, and this effects may have been caused by ovarian abnormality, and due to toxicity exposure to NaF, the histopathological changes in the treated groups showed a decrease in the number of Graafian follicles with increase numbers of growing follicles, in addition to different stage of developing of atretic follicles and these results are in accordance with the Farooqi and Maity et al (14,15) which assign the decrease in the number of Graafian follicles to reduced number of cell, division of it, and to differentiation in germ cell through oogenesis. In rat's male genital system, testis and epididymis typical structures and the equilibrium between the secretion of estrogen and androgen are critical for maturation of sperm and formation of spermatogenesis, abnormality in function, structures, morphology of sperm not only impact the quality of semen, but also leading to infertility.…”

The current study aimed to determine the pathological effects of chronic poisoning with sodium fluoride on some reproductive organs like ovary, and testis of adult's male and female albino rats. Thirty-six male and female adult's albino rats were divided into six groups. The first and second group of male and female rats are control groups was given tap drinking water, the third and fourth groups of male and female rats was given 150 ppm of NaF, the fifth and sixth group of male and female rats was given 300 ppm of NaF respectively for 90 days. The weights of male and female genital were recorded. Histological exam of control groups of female rats showed the typical histological structure of the ovary, while the NaF treated groups showed a decrease in growing follicles, in addition to thickening in tunica albuginea and deposition of eosinophilic material. In male control groups, the sections showed the typical histological structures of the testis, while the treated groups showed multinucleated spermatids in addition to the deposition of amorphous eosinophilic material in the interstitial tissue, coagulative necrosis, in addition to apoptotic and sloughed spermatogonia in the lumen of seminiferous tubule. These results indicate that sodium fluoride with 300 ppm has toxic effects on organ body weights and on the histology of the gonads of adult's male and female albino rats.

“…The unsaturated condition of fluorite mineral both seasons was observed as -38 to 0, have suggested that fluorite mineral is more soluble in alkaline groundwater condition than other Fbearing minerals (Apambire et al, 1997;Farooqi 2015). In acidic groundwater condition, dissolution of minerals like amphiboles, micas and apatite is more favourable than fluorite mineral (Farooqi, 2015). The groundwater aquifer were observed rich in biotite and amphibole minerals, it is an indirect indication for the high F concentration in groundwater, beacsue fluorine substitutes a hydroxyl group from the biotite and amphiboles minerals (Edmunds and Smedley, 1996).…”

Identification and management of safe groundwater supply in a high As and F− contaminated region is a major concern facing most of the developing countries worldwide. This study provides a comprehensive hydrogeochemistry result for a complex hydro-stratigraphy soil aquifer, which is bound between the Shillong plateau and Himalayan ranges in the North-Eastern region of India. In this study, distinct contaminated regions of As and F− were identified in rainy (n = 94) and winter (n = 50) seasons groundwater samples. The maximum dissolved concentration of As was measured as 71 µg L− 1 in rainy and 211 µg L− 1 in winter season groundwater samples, whereas maximum F− concentration was measured as 7 mg L− 1 in rainy and 6 mg L− 1 in winter season groundwater samples. Identified minerals saturation condition, weathering, and dissolution results of hydrogeochemistry were well corroborated with the Bivariate plot, Gibbs and Pourbaix diagrams. Results of health risk assessment showed that population of age below 18 years old are prone to carcinogenic diseases and symptoms of non-carcinogenic health risk due to daily consumption of As contaminated groundwater. Children of age below 18 years old, in total 39% (i.e. 6834) and 64% (i.e. 13937) were found more susceptible to arsenic ingestion effect. The male population was found prone to As cancer risk than the female population. Overall, this study provides a critical result about the cause of high As and F− concentration in groundwater and health risk assessment, it provides a prime concern matter for the young generation which is at higher risk of As cancer.

“…Các kết quả nghiên cứu trước đây đã cho thấy 25 quốc gia trên thế giới có nồng độ florua cao trong các nguồn nước và khoảng 200 triệu người sống dựa vào các nguồn nước có chứa quá nhiều florua gây hậu quả nghiêm trọng đến sức khỏe người tiêu dùng [4][5]. Các quốc gia được ghi nhận trong bản đồ ô nhiễm fluor thế giới điển hình bao gồm Ethiopi (8 đến 10 triệu người bị ảnh hưởng; [6]); Mexico (5 triệu người bị ảnh hưởng; [7]); Argentina (1,2 triệu người; [8]). Châu Âu là khu vực có rủi ro thấp, chỉ có một số khu vực như Tây Ban Nha [9] và Nauy [10].…”

“…Còn ở các xã có tỷ lệ người dân có nguy cơ nhiễm bệnh cao như Ninh Sim lại là khu vực có hàm lượng F khá thấp (0,96 mg/l) [15]. Riêng đối với xã Ninh Trung là khu vực có hàm lượng F cao (0,3-1,9 mg/l) [7]; (0,5-2,8 mg/l) [8] thì tỷ lệ người dân có nguy cơ nhiễm bệnh tuy đã giảm nhưng vẫn còn ở mức cao (45%).…”

Dental fluorosis-a major, but preventable, oral diseases and public oral health problems-related with exceeded the fluoride level in natural groundwater sources. Dental fluorosis remains as a major public health problem worldwide, including Vietnam. Previous studies carried out since the 2000s demonstrated a link between dental fluorosis and increased fluoride levels in drinking water of Ninh Hoa town, Khanh Hoa province. The aim of this study was to determine the temporal variation of district's population, who at risk for dental caries or dental fluorosis, with questionair survey in Ninh Hoa town. The results indicated that the rate of population at risk for dental fluorosis, has been decreased in comparision with previous studies. In especially, in the vulnerable area with high fluorid zones like Ninh Xuan, Ninh Phung wards (> 6mg/L), the number of population at risk decreases to only 18 and 12%, respectively. Overall, only 25% district's population were risk of potential dental fluorosis. It is the results from implementation of drinking water supply projects from government. However, the long-term operation of the replacement of groundwater project need to be further strengthened. In addition, a further study on dental fluorosis and sources of F should be carried out.
