Poor groundwater quality and high potential health risks in the Datong Basin, northern China: research from published data
Abstract Datong Basin in China is a typical arid-semiarid inland basin, with high levels and wide distributions of arsenic (As), fluoride (F–), and iodine (I). To better understand the presence of low-quality groundwater in Datong Basin and assess the health risks for local residents, groundwater samples were collected from the shallow aquifer and in medium-deep […]China
Increased health threats from land use change caused by anthropogenic activity in an endemic fluorosis and arsenicosis area
Highlights Human activity causes a threat on children’s health. Land use change caused by human activity increased fluoride and arsenic concentrations in groundwater. Groundwater under industrial land suffered more serious pollution, especially at the junction of urban and suburban areas. Reasonable land use instruments, groundwater protection policies and regular monitoring are necessary. Abstract Urbanization is […]China
Hydrochemical relationship between shallow fluoride and underlying Paleozoic carbonates groundwaters.
Abstract In the arid to semi-arid district of Chengcheng, Weinan City, in central Shaanxi Province, diminishing groundwater reserves in the shallow Quaternary (QLB) aquifer and elevated fluoride in the similarly shallow Permo-Triassic (PTF) aquifer, have promoted interest in the development of groundwater resources in the deep but poorly understood Cambrian-Ordovician carbonate aquifer system (COC). To […]China
New Antidumping Petition on Difluoromethane from China
Note from Fluoride Action Network Difluoromethane, CAS No. 75-10-5, is a refrigerant and a substitute for ozone destroying chemicals. See EPA discussion of R-448A (a substitute) here. It’s structural formula is: Arkema Inc. (“petitioner”), on January 23, 2020, filed an antidumping (AD) petition on imports of difluoromethane (or “R-32”) from China. The U.S. AD law […]China Greenhouse/Ozone Gases
Potential risk assessment of groundwater to address the agricultural and domestic challenges in Ordos Basin.
Note from Fluoride Action Network: The Ordos (Eerduos, Shan-Gan-Ning) basin is located in the western part of the Sino-Korean (North China) craton. The basin is bordered by the Helanshan and Liupanshan on the west, by the Qinling Mountains on the south, by the Yinshan and Langshan on the north, and by the Shanxi plateau on […]China
Assessment of water quality of best water management practices in lake adjacent to the high-latitude agricultural areas, China.
Abstract A major inland alkalinity lake in Northeast China, the Chagan Lake, was studied for the changes of its water qualities over the past three decades. Water quality data, including total nitrogen (TN), total phosphorus (TP), pH, dissolved oxygen (DO), and fluoride (F–), were analyzed to derive key indices for guiding water quality management. Our […]China
Assessment of background levels and pollution sources for arsenic and fluoride in the phreatic and confined groundwater of Xi’an city, Shaanxi, China.
Abstract The presence of arsenic and fluoride in groundwater and their impacts on human health have been reported in many countries worldwide, but little information is available on As or F– contamination in Xi’an city. This study highlights the distribution and sources of As and F– anomalies in different aquifers of Xi’an city, based on […]China
Assessment of potential health risk of major contaminants of groundwater in a densely populated agricultural area
Note from Fluoride Action Network: “Since all methods [to remove fluoride] produce a sludge with very high concentration of fluoride that has to be disposed of, only water for drinking and cooking purposes should be treated, particularly in the developing countries.” Reference: Fluorosis (see Interventions), World Health Organization Abstract As a key part of Bohai […]China
Spatial distribution of fluoride in drinking water and health risk assessment of children in typical fluorosis areas in north China.
Highlights Fluoride content in drinking water for fluorosis areas in Tianjin was investigated. MWS system has a better effect on reducing water fluoride concentration. Younger children (1–4 years old) are more vulnerable to high fluoride exposure. Special attention should be paid to health education strategies against fluorosis. Abstract China has been suffering from endemic fluorosis […]China
Entech: Fluoride-Ion Batteries Will Deliver Up to Eight Times Longer Battery Life Than Lithium Cells
HONG KONG, Nov. 8, 2019 /PRNewswire/ — Lithium cells became commercially available close to the 1970s and although the technology has seen its fair share of improvements, it will soon be superseded by Fluoride-ion technology in the years to come owing to the continuous efforts of Hong Kong battery company, Entech International (H.K.) Limited. Fluoride-ion technology […]China Batteries
