WOW!! Fighter is Toxic!

As already reported, in 2019, an fighter crashed into a large warehouse in California and the incident left 13 people injured.In fact, the impact site of a crashed can be extremely dangerous and one of the main hazards is Hydrazine. Hydrazine is a colorless liquid that feeds the electrical systems and the EPU (Emergency Power Unit) as part of a backup power system on the aircraft. When activated, the unit provides emergency power for the aircraft’s systems in the case of an electrical failure: in case of flame-out, emergency power generated by the EPU is designed to give pilots the time they need to land the aircraft safely. And the EPU is fired up by Hydrazine.


The term hydrazine may sound unfamiliar, but hydrazine has been lurking in our lives all along. Hydrazine is easy to evaporate into the air and water-soluble easily. And the fish in the rivers which has been polluted will be toxic . If you eat the fish, hydrazine will be accumulated in your body. And there is also exposure to small amounts of hydrazine through indirect inhalation of cigarette smoke or use of tobacco products. An accumulation of hydrazine will lead to cancer risk.


Since we can't see it and touch it, how can we know it exists? Here, general techniques provided for detecting HZ in the trace amounts are presented: chromatography, capillary electrophoresis, chemiluminescence, spectrophotometry and etc... The above methods are limited because they are laborious, need complicated equipment and instrumentation, and are expensive. Nonetheless, it is expected that electro-chemical methods have some hopes because of the advantages of the increased sensitivity, simplified operations, affordability, shorter time for analyses and portability.
