Chemical Agent: Mustard gas, (S(CH 2 Cl)2 EFFECTS: A BLISTER AGENT Agent burns skin, eyes and lungs as it is absorbed, causing large blisters on skin and inside lungs and windpipe. STATE AT ROOM TEMPERATURE: At room temperature, mustard gas is a liquid which gives off a vapour, but it can also be made into an aerosol or dust. MOLECULE SIZE: 1. 692 nm Chemical Agent: Concentrated Hydrochloric acid EFFECTS: corrosive to the skin STATE AT ROOM TEMPERATURE: Liquid Chemical Agent: Hydrogen cyanide EFFECTS: BLOOD AGENT Reduces the body’s ability to carry oxygen, particularly affects the lungs and heart, only takes minutes to stop the heart. STATE AT ROOM TEMPERATURE: A colourless gas. MOLECULE SIZE: 0. 859 nm Chemical Agent: Hydrogen cyanide EFFECTS: BLOOD AGENT Reduces the body’s ability to carry oxygen, particularly affects the lungs and heart, only takes minutes to stop the heart. STATE AT ROOM TEMPERATURE: A colourless gas. MOLECULE SIZE: 0. 605 nm MOLECULE SIZE: 0. 859 nm

Chemical Agent: Variola Virus Chemical Agent: Sarin EFFECTS: NERVE AGENT Damages synapses so that nerve impulses cannot be sent. STATE AT ROOM TEMPERATURE: Gas. EFFECTS: A virus that causes smallpox. A brief rash on the upper body followed by general malaise, fever, muscle stiffness, vomiting, headache, backache with delirium occurring in about 15% of cases. Can be fatal. STATE AT ROOM TEMPERATURE: Air-borne virus. MOLECULE SIZE: 1. 341 nm MOLECULE SIZE: 220 nm Chemical Agent: Carbon dioxide A waste gas from the process of respiration, which occurs in the mitochondria of cells to produce energy STATE AT ROOM TEMPERATURE: A colourless gas MOLECULE SIZE: 0. 556 nm Chemical Agent: Oxygen A gas needed for the process of respiration, which occurs in the mitochondria of cells to produce energy STATE AT ROOM TEMPERATURE: A colourless gas. MOLECULE SIZE: 0. 384 nm

Chemical Agent: Anthrax Chemical Agent: Water A waste gas from the process of respiration, which occurs in the mitochondria of cells to produce energy. STATE AT ROOM TEMPERATURE: A colourless gas MOLECULE SIZE: 0. 536 nm Anthrax comes from the bacterium Bacillus anthracis. Cutaneous anthrax, if it comes into contact with the skin, can cause ulcers: rarely fatal. If Anthrax is inhaled it can cause respiratory problems (fatal) STATE AT ROOM TEMPERATURE: If present in large quantities looks like a fine white powder MOLECULE SIZE: 1000000 nm
