Chinese authorities are trying to find out what potent mix of chemicals caused the explosions in
Chemicals that authorities have said to be potentially stored in the warehouse include:
Produces the highly poisonous gas hydrogen cyanide when dissolved or burned, and was used in executions in America. It is highly toxic if inhaled or ingested, flammable and can cause asphyxiation. Symptoms include vomiting, diarrhoea, burning sensations, sore throat, convulsions, and unconsciousness. If this isn't sufficiently cleaned up and there's rain, the rain could also spread chemicals on the ground into the air when it evaporates.
Its dust is easy to inhale and it is also soluble in water, raising concerns that it may have contaminated drain water.
Potassium nitrate, sodium nitrate
Can cause explosions with toxic fumes if exposed to reducing agents. Symptoms include coughing, skin and eye irritation, dizziness, confusion, abdominal pain, breathing problems, convulsions, diarrhoea, nausea, unconsciousness, and blue lips, fingernails or skin.
Can amplify the combustion of other substances with toxic fumes. Symptoms include coughing, sore throat, headaches, irritation to skin and eyes, abdominal pain, convulsions, diarrhoeia, dizziness, vomiting and blue fingernails or lips.
Rain fell on the remains of the Tianjin blast site. This makes it much more difficult to clean up the deadly chemicals
Chemicals detected in the air the morning after the explosion include:
Very flammable. It can affect the nervous system, and cause confusion, memory loss, nausea, anxiety, loss of hearing/colour/vision/appetite, damages to kidneys and liver, and unconsciousness.
Can produce toxic flames when heated, as well as explosions. Symptoms from exposure include irritation, dizziness, confusion, abdominal pain, vomiting, liver and kidney damage, and can also affect the nervous system.
Extremely flammable. It can cause drowsiness, coughing, nausea, vomiting, blurred vision, dry skin, blisters and frostbites (on contact with liquid). Long term symptoms include asthma, heritable genetic damage and nervous system damage.
Volatile Organic Compounds
Symptoms include dizziness, headaches, loss of vision/memory/coordination, allergic skin reaction, and eye and breathing problems. It can cause damage to the kidneys, liver and the central nervous system.
Chemicals detected in
’s underground drainage were: Tianjin
The effects depends on the compound, but symptoms include dizziness, headache, nausea, vomiting, rapid breathing and heart rate, convulsions, unconsciousness, low blood pressure, lung injury and respiratory failure.
