[Analysis on monitoring results of toxicological indicators of rural drinking water in Shaanxi Province from 2016 to 2018].
Abstract OBJECTIVE: To understand the toxicological indexes of rural drinking water quality in 2016-2018 in Shaanxi Province. METHODS: From 2016 to 2018, rural drinking water monitoring points were set up in all( 102) agriculture-related counties( districts) in Shaanxi Province. Each township selected 1-2 rural water supply systems for terminal water supply and terminal water and […]China
Fluoride contributes to the shaping of microbial community in high fluoride groundwater in Qiji County, Yuncheng City, China.
Abstract As a toxic element, excessive amounts of fluoride in environment can be harmful because of its antimicrobial activity, however little is known about the relationship between fluoride and the bacterial community in groundwater systems. Here, we use samples from a typical fluorosis area to test the hypothesis that fluoride concentration is a fundamental structuring […]China
Evaluation the Feasibility of Short-Term Electrodialysis for Separating Naturally Occurring Fluoride from Instant Brick Tea Infusion
Abstract BACKGROUND: Removing excessive naturally occurring fluoride from tea and/or infusions is difficult because the process has low efficiency and causes secondary pollution. In this study, a novel electrodialysis (ED) technology was developed. We examined the effect of crucial parameters (electrolyte concentration, operation voltage, ED duration, and initial concentration of the tea infusion) on the […]China International
Awareness of the Benefits and Risks Related to Using Fluoridated Toothpaste Among Doctors: A Population-Based Study.
Abstract BACKGROUND: This study aimed to assess the awareness of dentists and non-dental doctors regarding the benefits and risks of using fluoridated toothpaste. MATERIAL AND METHODS: A self-administered questionnaire was used to collect information in this study. Multistage cluster sampling method was used to enroll doctors in 5 districts or counties in Chongqing, China. A […]China Toothpaste
Geochemical factors controlling the occurrence of high-fluoride groundwater in the western region of the Ordos basin, northwestern China.
Abstract: Hydrogeochemistry and isotope hydrology were carried out to investigate the spatial distribution of fluoride (F–) and the mechanisms responsible for its enrichment in the western region of the Ordos basin, northwestern China. Sixty-two groundwater samples from the unconfined aquifer and fifty-six from confined aquifer were collected during the pre-monsoon (June 2016). Over 77% of […]China

A Tale of Two Water Supplies in China: Finding Practical Solutions to Urban and Rural Water Supply Problems
Abstract Conspectus Access to safe drinking water is among the 17 United Nations sustainable development goals. As the largest developing country, China has confronted large challenges to providing safe and sufficient drinking water to its population of 1.4 billion under the conditions of limited water sources and ubiquitous water contamination. This Account outlines these challenges […]China
Perfluoroalkyl substances in groundwater and home-produced vegetables and eggs around a fluorochemical industrial park in China
Highlights Increasing levels of PFBS and PFOA occurred in groundwater beneath the Fuxin FIP. Groundwater contaminations of PFBS and PFOA might pose health risks to residents. PFBA and PFBS were the major contaminants in home-produced vegetables and eggs. PFBA, PFOA, and PFBS could enter vegetables via irrigation with local groundwater. Abstract High-level contaminations of perfluoroalkyl […]China Perfluorinated chemicals
Accumulation, fractionation and health risk assessment of fluoride and heavy metals in soil-crop syst.
Abstract Highlights Water soluble F may increase the bioavailability of Cu, Mn, Zn, Pb, Ni, Cd and Cr. The combined stresses of Cu and Ni may be the main factor that increases F bioavailability. Contaminants easily accumulate in male inflorescence of maize except for roots and leaves. Crop grains and shoots cannot be used for […]China
Long term spatial-temporal dynamics of fluoride in sources of drinking water and associated health risks in a semiarid region of Northern China
Highlights F– levels of Taiyuan were in optimum range based on the recommendation by USEPA. Individual locations within industrial areas had higher F– levels. HRIsF were calculated and the highest associated with suburban areas. F– levels and HRIsF of the groundwater in Taiyuan showed a decreasing trend. HRIsF in suburban areas was higher than urban […]China Coal Industry
