After careful investigation, it was found that it was caused by a unit during tear gas throwing training. Combined with the meteorological data of air diffusion provided by the meteorological department, it is preliminarily judged that the pungent smell is caused by tear gas bombs thrown during training.
What is tear gas? What is the composition of tear gas?
Tear gas, also known as tear gas, is a non-lethal weapon. Among them, phenyl chloroethyl ketone and o-chlorobenzene methylene propionitrile are the most common components, while o-chlorobenzene methylene propionitrile is the most widely used component at present, and general special forces are often equipped with such weapons. Tear gas contains magnesium, aluminum, sodium nitrate, barium nitrate and other substances. After the tear gas bomb exploded, magnesium burned rapidly in the air, emitting ultraviolet rays and dazzling white light, and at the same time exothermic decomposition of nitrate, and the generated oxygen further promoted the combustion of magnesium and aluminum.
Tear gas contains a variety of highly volatile substances, which can stimulate sensitive parts of the human body, such as the mucous membranes of the eyes, ears, nose and mouth. Tear gas contains a liquid substance containing tears. Sometimes toxic SIES is used, which will lead to a lot of tears, severe cough and more than one sneeze, which is unbearable and even fatal in severe cases.
