“…Except the value reported by US NAS [25], Washington DC, America and Smith and Hodge [26], fluoride in American soil is lower than this study, while others such as Toma et al [27], Moldova; Shomar et al [28], Israel; Zhang et al [29], China and others have comparable value of total fluoride with this study. The water soluble content of soil in this study is a bit higher than that of reported in literature, but comparable values also reported in America [25] and New Zealand [30].…”

ABSTRACT. The levels of fluoride and selected metals in Ethiopian Rift Valley soils and irrigation water in the nearby sources were determined by fluoride ion selective electrode and flame atomic absorption spectrophotometer, respectively. The pH, conductivity, salinity and total dissolved solids in water and soil samples were also determined. Accuracy of the optimized procedure was evaluated using standard addition (spiking) method and an acceptable percentage recovery was obtained. The fluoride concentrations in water samples were found in the range of 0.14-8.0 mg/L which is below the WHO limit of fluoride concentration for irrigation (less than 10 mg/L). The water soluble and total fluorides in soil were 2.3-16 µg/g and 209-1210 µg/g, respectively and are within the ranges recommended by FAO and WHO. The range of metal concentration in soil samples (µg/g dry weight basis) and in water samples (mg/L) respectively were: Na (684-6703, 8.6-67), Mg (1608-11229, 23-67), K (1776-4394, 1.1-20), Ca (7547-22998, 17-267), Cr (9.8-79, 0.07-0.17), Mn (143-700, 0.05-37), Co (50-112, 0.35-1.5), Ni (446-1288, 0.27-41), Fe (12180-32681, 6.0-48), Cu (8.9-45, 0.09-0.25) and Zn (31-89, 0.14-0.56). Fluoride was found to have significant correlation with major trace metals (Fe, Cu and Cr), but the correlation with other trace metals was not significant.

“…Surprisingly low is the ranking for fluoride (6) as fertiliser associated fluoride has been reported to accumulate in soil (Loganathan et al 2001), and it can be highly toxic to some microorganisms. However, it is considered a moderate health risk to humans and plants.…”

A risk ranking model was developed to provide a systematic evaluation of the range and quantity of 28 elemental contaminants applied to land in New Zealand and applied to mineral P fertilisers. The methodology is transparent, flexible and robust and allows contamination issues to be ranked according to their real or potential impact. The quantitative ranking model is based on the relative importance of each element in relation to accumulation in soil, transfer to water or uptake by plants, toxicity to soil organisms, plants and people, and the contribution of any radioactive isotopes. The highest risk score for potential environmental significance of P fertiliser borne trace element contaminants was found for uranium, followed (in decreasing order) by cadmium, mercury, boron, fluoride, selenium, arsenic, silver and rare earth elements. The lowest score (rank 28) was attributed to strontium.

“…Discharges of fluorine from some industries, such as semi-conductors, steel, aluminum, glass, bricks, fertilizers and electroplating, are among the main anthropogenic sources of fluorine pollution (Cronin et al 2000). Phosphate fertilizers which contain fluorine are another important source of fluorine input to soils (Loganathan et al 2001). Now, soil fluorine pollution is a serious environmental problem in some areas of China.…”

Soil pollution of fluorine is a serious environmental problem in the world, and the fluorine pollution evaluation of spatial and vertical distribution study in the Karst region is quite limited. In this study, the farmland around lead-zinc mine in the Karst region was chosen as the study area. Ninety-one upper layer soil samples and two soil profiles (one in paddy field, the other one in aerated field) samples were taken. The average concentration of total fluorine of topsoil in the paddy fields is 378 mg/kg, whereas in the aerated field it is 508 mg/kg. The concentrations of total fluorine in all paddy soil samples and 97.87% aerated field soils are higher than that of the background value of Guangxi. The total fluorine contaminations in all aerated field soils are much higher than in paddy soil samples, so the aerated field is contaminated severely. The vertical distribution of fluorine is different in paddy field and aerated field. In paddy field, the content of fluorine increases from 20 to 40 cm, then it decreases rapidly from 40 to 60 cm in depth, and then increases gradually. However, in the aerated field, the content of fluorine rises gradually with the depth of the sampling point. The results of relative analysis and regression analysis between fluorine in soil and soil properties show that the spatial distribution and vertical variation of fluorine in this region are mainly affected by parent rock.
