“…Moreover, it summarizes most of the techniques already proposed. The effectiveness of various materials for fluoride removal has been reviewed, taking into account key factors such as pH, initial fluorine concentration, surface area, particle size, and temperature, as well as the occurrence of counterions influencing the process of defluorination [ 39 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 ].…”

Technological and economic development have influenced the amount of post-production waste. Post-industrial waste, generated in the most considerable amount, includes, among others, waste related to the mining, metallurgical, and energy industries. Various non-hazardous or hazardous wastes can be used to produce new construction materials after the “solidification/stabilization” processes. They can be used as admixtures or raw materials. However, the production of construction materials from various non-hazardous or hazardous waste materials is still very limited. In our opinion, special attention should be paid to waste containing fluoride, and the reuse of solid waste containing fluoride is a high priority today. Fluoride is one of the few trace elements that has received much attention due to its harmful effects on the environment and human and animal health. In addition to natural sources, industry, which discharges wastewater containing F− ions into surface waters, also increases fluoride concentration in waters and pollutes the environment. Therefore, developing effective and robust technologies to remove fluoride excess from the aquatic environment is becoming extremely important. This review aims to cover a wide variety of procedures that have been used to remove fluoride from drinking water and industrial wastewater. In addition, the ability to absorb fluoride, among others, by industrial by-products, agricultural waste, and biomass materials were reviewed.

Halogens in Seaweeds: Biological and Environmental Significance

Many marine algae are strong accumulators of halogens. Commercial iodine production started by burning seaweeds in the 19th century. The high iodine content of certain seaweeds has potential pharmaceutical and nutritional applications. While the metabolism of iodine in brown algae is linked to oxidative metabolism, with iodide serving the function of an inorganic antioxidant protecting the cell and thallus surface against reactive oxygen species with implications for atmospheric and marine chemistry, rather little is known about the regulation and homoeostasis of other halogens in seaweeds in general and the ecological and biological role of marine algal halogenated metabolites (except for organohalogen secondary metabolites). The present review covers these areas, including the significance of seaweed-derived halogens and of halogens in general in the context of human diet and physiology. Furthermore, the understanding of interactions between halogenated compound production by algae and the environment, including anthropogenic impacts, effects on the ozone layer and global climate change, is reviewed together with the production of halogenated natural products by seaweeds and the potential of seaweeds as bioindicators for halogen radionuclides.

“…Consequently, we estimate that 10% of the Li in CCRs is released to the atmosphere in particles, inferring a global Li flux of 55 × 10 9 g/year in 2019 (i.e., 10% of the Li flux from coal combustion escapes as fly ash aerosols). For comparison, we estimate that the losses of other elements to the atmosphere during coal combustion range from 1% to 2% for V (Schlesinger et al., 2017) to 27% for F (Schlesinger et al., 2020).…”

Lithium is the lightest alkali metal and is one of a group of three elements (Li, Be, and B) that are anomalously rare in the Universe based on the standard cosmological model (Malaney & Fowler, 1988;Vangioni & Cassé, 2018). Due to its particular chemical properties (i.e., low atomic mass, high reactivity, and easy exchange of the outermost of its three electrons), Li has become a key element in modern batteries. A typical electric vehicle battery, for example, may contain as much as 12 kg of Li, which-combined with other industrial applications-contributes to the growing worldwide demand for Li (Bibienne et al., 2020).Lithium is mined commercially from pegmatite minerals (e.g., lepidolite and spodumene) mostly in Australia and China. Large quantities of Li are also extracted from evaporite minerals and associated brines, with the largest production occurring in Chile, Argentina, and the United States. Current annual global production of Li is 77,000 mt/year (77 × 10 9 g/year; U.S. Geological Survey, 2020). At current use, proven reserves are expected to last for about 200 years, but demand for Li is estimated to increase 10-fold by 2050 (Sovacool et al., 2020). Junne et al. (2020) estimate that the ratio of cumulative Li demand to reserves may be as high as 6.5. Clearly, new deposits must be found, and large-scale recycling instituted, to accommodate increasing future demand.Although Li has no known role in biochemistry, it has long been used to treat bipolar disorder and other problems of mental health (Geddes et al., 2004). The mechanism of its efficacy has not been fully elucidated (Curran & Ravindran, 2014). At high levels, Li is toxic to plants (
