Perchlorate in antarctica, origin, effects, treatments, environmental fate, and astrobiological perspectives: a review
Perchlorate (ClO4−), which is a powerful endocrine disruptor affecting iodine fixation in the thyroid gland in humans and in biota, is a pollutant of natural and anthropogenic origin. For this reason, this pollutant must be eliminated from the ecosystems. It has been found in extreme environments such as Antarctica. ClO4− reduction can be achieved with physicochemical treatments in small concentrations and through bacterial degradation. This is a cost-effective method, easy to implement, which makes it a viable method for the removal of perchlorate contamination in ecosystems. This review provides an updated discussion of reducing perchlorate contamination; that includes different perspectives of investigations related to its origin, use, effects on living beings; as well as the technologies used to eliminate this pollutant from the environment; its environmental fate in strategic ecosystems such as Antarctica in particular and astrobiological perspectives.
期刊介绍：
International Journal of Environmental Science and Technology (IJEST) is an international scholarly refereed research journal which aims to promote the theory and practice of environmental science and technology, innovation, engineering and management.
A broad outline of the journal''s scope includes: peer reviewed original research articles, case and technical reports, reviews and analyses papers, short communications and notes to the editor, in interdisciplinary information on the practice and status of research in environmental science and technology, both natural and man made.
The main aspects of research areas include, but are not exclusive to; environmental chemistry and biology, environments pollution control and abatement technology, transport and fate of pollutants in the environment, concentrations and dispersion of wastes in air, water, and soil, point and non-point sources pollution, heavy metals and organic compounds in the environment, atmospheric pollutants and trace gases, solid and hazardous waste management; soil biodegradation and bioremediation of contaminated sites; environmental impact assessment, industrial ecology, ecological and human risk assessment; improved energy management and auditing efficiency and environmental standards and criteria.
