blood agents |
0.06 sec. |

blood agents, poisons that affect the body by being absorbed into the blood. Blood agents include arsine and cyanide. Exposure to both may occur by inhalation, and cyanide exposure may also occur by ingestion and absorption through the skin and eyes. Arsine causes hemolysis, resulting in generalized weakness, jaundice, delirium, and renal failure; high doses may result in death. There is no antidote and treatment is supportive. Cyanide prevents cells from using oxygen, leading to cell death, and poisoning especially affects the cardiovascular and nervous systems and can lead to heart and brain damage and death from respiratory failure. Treatment consists of the administration of an antidote and supportive care. How to thank TFD for its existence?

| They can be divided into different classes: choking agents (phosgene, chlorine, nitrogen oxides); blister or vesicants (mustard gas, lewisite, phosgene oxime); blood agents (cyanogen chloride, hydrogen cyanide); nerve agents (sarin, soman, tabun, VX); and incapacitating agents (tear gas, pepper spray). JCAD is designed to detect, identify and quantify nerve, blister, blood agents and toxic industrial chemicals at low levels to allow sufficient time for protective measures to be taken. In a June supplement to ENVIRONMENTAL HEALTH PERSPECTIVES, Schwartz reports that of all the pollutants measured, only fine particulates--those smaller than 10 micrometers in diameter--were associated with higher than normal concentrations of these blood agents. |
