Impacts of the element fluorine: bibliographical review
Keywords:
fluorine, toxicity, ecosystemAbstract
The objective of this study was to conduct a literature review to highlight the negative impacts that fluorine toxicity can cause on the atmosphere, plants, animals and soil. Growing industrial production is considered one of the main sources of fluorine emissions into the atmosphere, such as the production of phosphate fertilizers. Plants absorb fluorine through their leaves, and after toxicity they may show reduced growth and loss of agricultural production. Some species are used as bioindicators to help monitor contamination levels. Fluorine poisoning in animals usually occurs in a chronic or subacute form, and rarely occurs in an acute form. Symptoms caused in animals by excess fluorine include fluorosis, which presents stains on the teeth and deformities in the enamel. In the soil, fluorine pollution is present in the colloidal or clay fraction of the soil, indirectly modifying soil properties. Therefore, it is necessary to understand the negative effects that fluorine toxicity causes to ecosystems, so that research and technical work can be carried out with the aim of minimizing these impacts.
