“…Long-term drinking of high-fluorine water can result in dental fluorosis, skeletal fluorosis [2], as well as the lesions of tissues and organs (such as the endocrine glands, thyroid and liver) [3]. Fluoride contamination in the groundwater occurs in any parts of world, particularly in Bangladesh, Thailand, Pakistan, China, India, Africa, and Mexico [4]. Elevated fluoride concentrations in the groundwater derives mainly from natural dissolution of minerals from rocks and soils [5].…”

“…It is well recognized that the quality of agricultural water is very important for food safety and quality of life. Toxic cations, such as heavy metal ions, have been a serious ecological problem due to bioaccumulation through the food chain, while anions, such as SO 4 2− , Cl − and CO 3 2− , can cause soil consolidation or decrease soil fertility [7]. It is common that the groundwater (or surface water) can be used directly without purification for agricultural irrigation.…”

The removing of fluoride from water is highly desired from the viewpoint of environmental protection and sustainable development due to the adverse impacts on human and ecosystem. In this study, the hierarchical porous layered double hydroxide (LDH)/biomass carbon fiber (BCF) has been successfully fabricated by the combined sol-gel, carbonization and hydrothermal processes using sustainable bamboo fibers as raw material based on the assembly the LDH nanosheets on BCF surfaces. Structural characterization indicates that the LDH nanosheets were attached to the BCF surface via in situ crystal growth. N 2 sorption measurements show that the LDH/BCF has relatively uniform accessible mesochannel size of 3.56 nm, and the surface area is as high as 39.89 m 2 /g. The resulting LDH/BCF exhibit a noticeable enhanced adsorption capacity for fluoride removal compared to that of Al 2 O 3 /BCF, accompanied by 15.21 mg/g of the adsorption capacity. The presence of the high negative charge anions had negligible influence on fluoride adsorption. Importantly, recovery adsorption capacity for fluoride was obtained for LDH/BCF for 5 consecutive cycles without a significant decrease in its adsorption properties. Therefore, the current research can offer a green approach to fabricate LDH/BCF with hierarchical structures for efficient removing fluoride from water, and the fabricated LDH/BCF will be an excellent candidate for pollution control based on the synergistic effects of BCF and LDH, high adsorption properties with good reusability. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

“…Furthermore, epidemiological studies have shown that long term exposure to arsenic can increase the risk of cancers of lung, skin or bladder in man [2]. The Environmental Protection Agency and World Health Organization, in spite of that, have lowered the acceptable limit of arsenic in drinking water to 10 ppb, the concurrence of inorganic arsenic in groundwater has been reported in many Latin America and Asia countries, where inorganic arsenic concentration is up to 5300 ppb [3, 4]. For one thing, Gaworecki et al [5] have reported that 25 ppm arsenic-exposed killifish during embryogenesis could initiate molecular changes that appeared to lead to aberrant muscle formation.…”

In many organ dysfunctions, arsenic and its compounds are well known to induce apoptosis by the mitochondria and death receptor apoptotic pathways in liver and airway. However, it is less reported that which signaling pathways contribute to excessive apoptosis of chicken immune organs, a major target of toxic metals biotransformation, which suffer from subchronic arsenism. In this study, we investigated whether the mitochondria or death receptor apoptotic pathways activated in the immune organs (spleen, thymus and bursa of Fabricius) of one-day-old male Hy-line chickens exposed to arsenic trioxide (As2O3), which were fed on diets supplemented with 0, 0.625, 1.25 and 2.5 mg/kg BW of As2O3 for 30, 60 and 90 days. We found that (1) Oxidative damage and inflammatory response were confirmed in the immune organs of chickens fed on As2O3 diet. (2) Subchronic arsenism induced typical apoptotic changes in ultrastructure. (3) TdT-mediated dUTP Nick-End Labeling (TUNEL) showed that the number of apoptotic cells significantly increased under subchronic arsenism. (4) As2O3-induced apoptosis of immune organs involved in mitochondrial pathway (decrease of B-cell lymphoma-2 (Bcl-2) and increase of protein 53 (p53), Bcl-2 Associated X Protein (Bax), caspase-9, caspase-3) and death receptor pathway (increase of factor associated suicide (Fas) and caspase-8). In conclusion, this work is the first to demonstrate that the activation of mitochondria and death receptor apoptosis pathways can lead to excessive apoptosis in immune organs of chickens, which suffer from subchronic arsenism, meanwhile, oxidative stress as well as subsequent inflammatory is a crucial driver of apoptosis.

“…Natural genesis of high arsenic (As), fluorine (F) or iodine (I) in groundwater have been reported in many areas of northern China, such as Songnen Plain, Hetao Plain, and Datong Basin [1][2][3][4]. Migration and transformation of groundwater arsenic, fluorine and iodine vary with the variation of hydrogeochemical conditions.…”

“…Migration and transformation of groundwater arsenic, fluorine and iodine vary with the variation of hydrogeochemical conditions. Endemic arsenicosis, fluorosis and iodism seriously threaten human health [5].In China, the limits for As, F and I in drinking water are 10 µg/L, 1.0 mg/L and 0.08 mg/L, respectively [4]. The enrichment of groundwater As, F and I in parts of Xinjiang Uygur Autonomous Region (hereinafter referred to as "Xinjiang") is a threat to the health of local residents [6][7][8].…”

Test results on 302 shallow groundwater samples in an oasis zone in the southern margin of the Tarim Basin in Xinjiang were collected and analysed for a large number of chemical parameters and subjected to mathematical statistics methods. Results show that groundwater with high arsenic, fluorine and iodine concentrations were mainly distributed in the Minfeng County in the central part of the study area. Shallow groundwater in the southern margin of the entire Tarim Basin generally had high fluorine concentrations. The distribution of arsenic and fluorine in groundwater were similar. Intensive evaporation under the arid climatatic condition was an important factor for the enrichment of arsenic, fluorine and iodine in groundwater.
