Abstract

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.

南极洲的高氯酸盐、起源、影响、处理方法、环境归宿和天体生物学视角：综述

高氯酸盐（ClO4-）是一种强烈的内分泌干扰物，会影响人类甲状腺和生物群的碘固定，是一种源自自然和人为的污染物。因此，必须从生态系统中消除这种污染物。在南极洲等极端环境中已经发现了这种物质。可以通过物理化学处理和细菌降解来减少小浓度的 ClO4。这种方法成本效益高，易于实施，是消除生态系统中高氯酸盐污染的可行方法。本综述对减少高氯酸盐污染进行了最新讨论，包括从不同角度研究高氯酸盐的来源、使用、对生物的影响，以及用于消除环境中这种污染物的技术；高氯酸盐在战略生态系统（特别是南极洲）中的环境归宿和天体生物学观点。

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.
