Aftermath of the 2020 Beirut explosion.. The most dangerous chemical accident recorded in history was the 1984 Bhopal gas tragedy in India, in which more than 3,000 people died after highly toxic methyl isocyanate was released at a Union Carbide pesticides factory.
Most of the victims died from inhaling poisonous gases, including carbon monoxide. After the fire, the technical institution INTI found that the level of toxicity due to the materials and volume of the building was 225 ppm of cyanide in the air. A lethal dose for rats is between 150 ppm and 220 ppm, meaning the air in the building was highly toxic.
Some polymerization reactions such as the setting of epoxy resin; The reaction of most metals with halogens or oxygen; Nuclear fusion in hydrogen bombs and in stellar cores (to iron) Nuclear fission of heavy elements; The reaction between zinc and hydrochloric acid; Respiration (breaking down of glucose to release energy in cells)
There is no antidote for strychnine poisoning. [5] Strychnine poisoning demands aggressive management with early control of muscle spasms, intubation for loss of airway control, toxin removal (decontamination), intravenous hydration and potentially active cooling efforts in the context of hyperthermia as well as hemodialysis in kidney failure (strychnine has not been shown to be removed by ...
Though some flash powders are too volatile and dangerous to be safely used, there are milder compounds that are still incorporated into performances today. Silver Fulminate is used to make noise-makers, small contact poppers, and several other novelty fireworks. [12] It is most widely used in bang snaps. In these small explosives, a minuscule ...
A 37-year-old acid attack victim from Tabriz, Iran. An acid attack, [1] also called acid throwing, vitriol attack, or vitriolage, is a form of violent assault [2] [3] [4] involving the act of throwing acid or a similarly corrosive substance onto the body of another "with the intention to disfigure, maim, torture, or kill".

Mercury poisoning is a type of metal poisoning due to exposure to mercury. [3] Symptoms depend upon the type, dose, method, and duration of exposure. [3] [4] They may include muscle weakness, poor coordination, numbness in the hands and feet, skin rashes, anxiety, memory problems, trouble speaking, trouble hearing, or trouble seeing. [1]
Biocides need not be poisonous to humans, because they can target metabolic pathways absent in humans, leaving only incidental toxicity. For instance, the herbicide 2,4-dichlorophenoxyacetic acid is a mimic of a plant growth hormone, which causes uncontrollable growth leading to the death of the plant. Humans and animals, lacking this hormone ...
