How do chemical agents affect human health?

How do chemical agents affect human health? Chemicals can enter and irritate the nose, air passages and lungs. They can become deposited in the airways or be absorbed by the lungs into the bloodstream. The blood can then carry these substances to the rest of the body. Ingestion (swallowing) of food, drink or other substances is another route of exposure.

What chemicals affect the nervous system?

Although genetic factors play a role, neurotoxins such as arsenic, chlorpyrifos, DDT (dichlorodiphenyltrichloroethane), ethyl alcohol, fluoride, lead, polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), manganese, mercury, and toluene are major contributors to the prevalence of neurobehavioral

How does nerve gas affect the body?

All nerve agents cause their toxic effects by preventing the proper operation of an enzyme that acts as the body’s “off switch” for glands and muscles. Without an “off switch,” the glands and muscles are constantly being stimulated. Exposed people may become tired and no longer be able to keep breathing.

What is the deadliest chemical weapon?

VX is the most potent of all nerve agents. Compared with the nerve agent sarin (also known as GB), VX is considered to be much more toxic by entry through the skin and somewhat more toxic by inhalation.

What gas melts skin?

Sulfur mustard is a type of chemical warfare agent. These kinds of agents cause blistering of the skin and mucous membranes on contact. They are called vesicants or blistering agents. Sulfur mustard is also known as “mustard gas or mustard agent,” or by the military designations H, HD, and HT.

Is poison gas still used today?
