Noteworthy multi-disciplinary undertakings have been taken to investigate the effects of natural fluoride ion (F) contamination since the preceding century. Fluoride is a hazard to the earth and human prosperity. Developed and developing countries are standing up to such enormous extents of issues in light of fluoride in the drinking water. Human use to fluoride has bourgeoned since World War II, on account of fluoridated water and toothpaste just as to the normal defilement by huge ventures, from aluminium to pesticides, where fluoride is an essential mechanical concoction similarly as a waste product. The chapter deals with the proportion of fluoride in nature and its impact on human prosperity, generally on the brain, endocrine system, thyroid, pineal gland, immune system, reproductive system, and organ systems. High assemblies of F in soil may really bargain the life of plants, obliterate soil microbial development, upset the soil environment, and cause soil and water defilement. This chapter further emphasizes various biological approaches for the remediation.

The high calibre of ways of life and the wellness of nature are immediately related to one another. The expanding frequency of animal and human medical problems because of modern contamination and anthropogenic changes has pulled in global intrigue and endeavours to discover new solutions for higher control and support the ecological measure (Ahmed, 2007; Tsiros et al., 1998). Poisonous contaminations may moreover be discharged to the earth by utilizing the air, soil, and water. Stack emanations to the air may furthermore add contamination to the soil which may moreover collect in plants by means of their ground rules. These contaminants amass in the food chain and afterward affect individuals and untamed life. Because of variations in home grown and anthropogenic exercises, universal contamination is developing and prompting sickness of the environment with metals, non-metals, natural chemical assemblies, and inorganic mixtures. The first supporters of this defilement are pesticides, sewage removal, bug sprays, herbicides, and the uncontrolled release of squanders. In the industrialized world, a gigantic segment of the populace is revealed every day to an assortment of concoction substances and poisonous metals which are unsafe for human wellness (Figure 1,3). Combinations with the fluorine component are altogether used in almost each organic industry, and air contamination through the fluoride ion (F) is colossal on the earth. In spite of the fact that F has an anticaries impact when applied topically to the teeth, fluorine isn't a key trace element and isn't significant for the improvement of sound teeth and bones (Chouhan and Flora, 2010; SCHER, 2011). Inordinate F admission may moreover antagonistically influence the wellness of animals and plants (Koblar et al, 2011). Fluoride is dispensed generally all through soils, plants, and animals, and is thought to be a quintessential component in animals. Fluoride has a significant capacity in bone mineralization and development of dental lacquers. Fluoride, when ate up in deficient segments (under 0.5 ppm), motives medical problems, for example, dental caries, absence of arrangement of dental veneer, and diminished bone mineralization, explicitly among youths (WHO, 1996). Interestingly, when fluoride is fed on in extra (more than 1 ppm), medical problems may additionally result, which likewise influence the young and old (WHO, 1996). At more noteworthy fluoride fixations, metabolic procedures are influenced in humans, and overexposed people can likewise experience the ill effects of skeletal or dental fluorosis, non-skeletal appearances, or combos of these ailments (Susheela et al., 1993). The occurrence and seriousness of fluorosis depends upon the fluoride fixation in air, soil or water, and the level of introduction to these levels (Table 1).

Among the three sorts of typical media (air, soil, and water), groundwater is the central inception of fluoride collaborator in humans and animals. To sustain life, freshwater must be continually available to individuals. Since the beginning, individuals have relied upon groundwater as a wellspring of drinking water, and even today, most of the people depend on tons of groundwater for persistence. Groundwater includes 97% of all-out freshwater, and in various areas, groundwater sources build up the single greatest available supply of fresh drinking water (WHO, 2004). Exactly when the paces of groundwater extraction outperform stimulate rates, weariness of this significant resource occurs, with a resultant confinement of the drinking water supply.
