“…A review published in 2018 [85] has been focused on global perchlorate pollution of water. The authors concluded that most of the peer-reviewed studies (n=39; 51%) were conducted in USA and Canada and further studies in different geographical regions seem to be essential [85]. An example from India, where mean concentration of ClO [92] was overrun.…”

Interest in perchlorate as environmental pollutant has increased since 1997, when high concentrations have been found in the waters of the Colorado River, USA. Perchlorate is very persistent in nature and it is slowly degraded. Although harmful effects of large doses of perchlorate on thyroid function have been proven, the environmental effects are still unclear. The primary objective of the present review is to collect prevailing data of perchlorate exposure and to discuss its impact on human health. The results show that more than 50% of reviewed works found significant associations of perchlorate exposure and human health. This review consists of the following sections: general information of perchlorate sources, its properties and determination methods, role and sources in human body including food and water intake, overview of the scientific literature on the research on the effect of perchlorate on human health from 2010 to 2020. Finally, conclusions and recommendations on future perchlorate studies concerning human exposure are presented.

“…Natural resources of perchlorate are found in abnormal condition. Perchlorate produce by serial reaction in environment involving electrical discharge lighting, oxidation of ozone and UV exposure [24], [26], [27].The perchlorate has also produce by natural sources through photochemical reaction in the environment including inorganic chlorine with ozone [24] and organic chlorine species like methyl chlorine which converted into a inorganic species [25]. After that it contributes to make perchlorate in stratosphere.…”

Perchlorate is a highly toxic compound. It has both chemical and physical properties. Perchlorate is not easily degradable compound by both bio and non-bio degradation process because of its high stability, highly water soluble compound and low absorption. That’s why perchlorate reduction becomes a big challenge. In this research work we studied different type of electrochemical technique and effect of different electrodes on these techniques. In present days, many techniques were developed for the detection or reduction of perchlorate such as bio-degradation, optical, chemical, electrochemical and microbial technique. This article gives information about application of electrochemical technique for the detection or reduction of perchlorate. The electrochemical techniques have various types for the detection of ion. These techniques grouped on the behalf of various types of electrical signal such as potential or voltage, current and impedance which were produce in the presence of perchlorate into aqueous solution. Electrochemical technique such as impedance spectroscopy, this technique was performed on the electrochemical work station by applied a constant range of frequency. In cyclic voltammetry technique we were given a constant potential range and found results in the form of oxidation and reduction current. In the reduction of perchlorate history various researcher was found results using different electrochemical technique on different types of electrodes. The perchlorate salts and perchlorate have some useful application in the defense field, batteries, automobile airbags, rocket propellants and fuels. Perchlorate contamination is become a worldwide health problems. In many western states perchlorate was found in ground and surface water. It disturbs the thyroid gland to uptake iodine the human body. So its prevention technique was needed. However, the electrochemical techniques have more advantage such as low cost, user friendly, label free and real time monitoring over all other techniques. So we focus on electrochemical detection technique for the perchlorate.

“…As one kind of thyreotoxin, 1 perchlorate (ClO4 -) salts have caused global ecosystem pollution and become a new research topic in academic fields, [2][3][4][5] especially the environment and food. Current strategies for ClO4detection employs unwieldy or expensive analytical apparatuses [6][7][8][9][10] (e.g.…”

Perchlorate (ClO4 -) has aroused wide concern as a global ecosystem pollutant, especially in the aquatic environment. A rapid and visible detection of ClO4in aqueous solution using alkali methylene blue (MB) and liquid-liquid extraction (LLE) was established with high selectivity and sensitivity. The alkali MB exclusively change from red into blue in organic solvent when exposed to aqueous ClO4 -. Organic solvent, amount of MB and alkalinity of solution were systematically optimized, while underlying mechanism was revealed using UV-vis spectroscopy and mass spectrometry.Under optimum conditions, the UV-vis absorbance at 600 nm showed a good linear relationship with the concentrations of ClO4in the range of 0.0025-0.025 mM (R 2 = 0.9945). The visual detection limit was 0.005 mM in environmental water and 0.02 mM in black tea infusion. This method provides an economical and simple visual detection of ClO4in aqueous solution.
