“…The adverse effect of this xenobiotic resulting in a decreased biomass of rice was not manifested until higher doses of fluorine, such as 50 and 100 mg F kg −1 of soil, were applied. Elrashidi et al (1998) demonstrated experimentally that a dose of 100 mg F kg −1 of soil caused a significantly negative effect on the biomass of spring barley. The report by Pant et al (2008) points to the toxic influence of fluorine on such plants as mustard green, chickpea, common wheat, and tomatoes.…”

The research was based on a pot experiment, in which the response of eight species of crops to soil contamination with fluorine was investigated. In parallel, some inactivating substances were tested in terms of their potential use for the neutralization of the harmful influence of fluorine on plants. The response of crops to soil contamination with fluorine was assessed according to the volume of biomass produced by aerial organs and roots as well as their content of N-total, N-protein, and N-NO3 −. The following crops were tested: maize, yellow lupine, winter oilseed rape, spring triticale, narrow-leaf lupine, black radish, phacelia, and lucerne. In most cases, soil pollution with fluorine stimulated the volume of biomass produced by the plants. The exceptions included grain and straw of spring triticale, maize roots, and aerial parts of lucerne, where the volume of harvested biomass was smaller in treatments with fluorine-polluted soil. Among the eight plant species, lucerne was most sensitive to the pollution despite smaller doses of fluorine in treatments with this plant. The other species were more tolerant to elevated concentrations of fluorine in soil. In most of the tested plants, the analyzed organs contained more total nitrogen, especially aerial organs and roots of black radish, grain and straw of spring triticale, and aerial biomass of lucerne. A decrease in the total nitrogen content due to soil contamination with fluorine was detected only in the aerial mass of yellow lupine. With respect to protein nitrogen, its increase in response to fluorine as a soil pollutant was found in grain of spring triticale and roots of black radish, whereas the aerial biomass of winter oilseed rape contained less of this nutrient. Among the analyzed neutralizing substances, lime most effectively alleviated the negative effect of soil pollution with fluorine. The second most effective substance was loam, while charcoal was the least effective in this respect. Our results showed the effect of soil contamination with fluorine on the yield and chemical composition of fluorine depended on the species and organ of a tested plant, on the rate of the xenobotic element and on the substance added to soil in order to neutralize fluorine.

“…The low migration of F − with depth could be attributed to the formation of fluoride complexes with other metals in the soil, e.g. Al, Fe, and Si [38,42]. Seasonal diversity was associated with a slight variation in F − content in the soil samples during the period of study.…”

“…For example, the geometric mean was 699 and 636 mg kg −1 in eastern washed leafy species and grasses, respectively. Literature concerning F − solubility in soil and plant uptake of F − [28,38,42] stated that, in an air-polluted area, the deposition of airborne HF was more significant than soil uptake because F − forms slightly soluble AlF3, CaF2 and fluorophogopite and complexes with Fe and Si, so that F − is poorly available to plants. The and PG erosion rather than absorption of F − from soil.…”

This study focuses on the determination of heavy metals and fluoride concentrations in the Syrian phosphate industry and in the vicinity of the phosphogypsum (PG) piles. Four sampling campaigns were carried out, in which 86 soil, 139 plant, 30 air particulate, 16 water, 12 PG, 6 phosphate ore (raw and treated) and 3 fertilizer samples were collected. Differential pulse anode stripping voltammetry was used for Pb and Cd determination, atomic absorption spectrometry was used for Zn, Cr and Cu determination, and instrumental neutron activation analysis was used for Se, Ni, As and Hg determination. Fluoride concentration was determined via fluoride ion selective electrode. The data revealed that most of the heavy metals were retained in the fertilizer. Fluoride content in PG was 0.47%. The presence of PG piles showed no impact on the run-off and ground and lake waters in the area. However, fluoride concentration was double the permissible airborne threshold in the sites to the east of the PG piles because of the prevailing wind in the region. Similarly, enhanced concentrations of fluoride were recorded for the eastern soil samples. The content of heavy metals in plants was element- and plant-specific and influenced by the element concentration in soil, the soil texture and the pH. The maximal mean of fluoride was found in the plants species of the eastern sites (699 mg kg(-1)), which mainly related to PG erosion and airborne deposition. Thus, the main impact of the PG piles was to increase the concentration of fluoride in the surrounding area. A national action should be taken to regulate PG piles.

“…However, in neutral pH, fluoride readily bound to soil surface and is not available to plants (Mondal and George, 2015). Most of the soluble F added to soils is converted into insoluble chemical forms which are not available to plants whereas addition of soluble F to soils of low pH can result in serious damage to vegetation (Elrashidi et al, 1998). Venkateswarlu et al (1965) found that almost 99% of the F absorbed by roots of Hordeum vulgare was desorbed in water, indicating that most of it was retained in the apoplast.…”

“…Fluoride forms its most stable bonds with Fe, Al, and Ca, and labile F is held by soil components that contain these elements, including clay minerals, calcium and magnesium compounds, and iron and aluminum compounds (Omueti and Jones 1977). Elrashidi et al (1998) indicated that F forms Al and Fe complexes which disrupt the mineral surfaces. Barrow and Ellis (1986) later predicted that at low pH, complexes between Al and F formed in soil solution and that little was present as free F -.…”

Fluorine is unique chemical element which occurs naturally, but is not an essential nutrient for plants. Fluoride toxicity can arise due to excessive fluoride intake from a variety of natural or manmade sources. Fluoride is phytotoxic to most plants. Plants which are sensitive for fluorine exposure even low concentrations of fluorine can cause leave damage and a decline in growth. All vegetation contains some fluoride absorbed from soil and water. The highest levels of F in field-grown vegetables are found up to 40 mg kg-1 fresh weight although fluoride is relatively immobile and is not easily leached in soil because most of the fluoride was not readily soluble or exchangeable. Also, high concentrations of fluoride primarily associated with the soil colloid or clay fraction can increase fluoride levels in soil solution, increasing uptake via the plant root. In soils more than 90 percent of the natural fluoride ranging from 20 to 1,000 g g-1 is insoluble, or tightly bound to soil particles. The excess accumulation of fluorides in vegetation leads to visible leaf injury, damage to fruits, changes in the yield. The amount of fluoride taken up by plants depending on the type of plant, the nature of the soil, and the amount and form of fluoride in the soil should be controlled. Conclusively, fluoride is possible and long-term pollution effects on plant growth through accumulation of the fluoride retained in the soil.
