| Gefahrenübersicht | The majority of exposures occur by inhalation and typically lead to symptoms of ocular, nasal, and respiratory tract irritation. Nonspecific gastrointestinal symptoms (e.g., vomiting or diarrhea) might also occur. The effects of adamsite poisoning take minutes to begin and might last for hours. If a rapid onset of manifestations of one of the following respiratory effects occurs, the clinical description for adamsite poisoning has been met: nose or throat irritation, cough, or dyspnea.

Anwendungen & Verwendung
Beschreibung
Adamsit bildet hellgelbe, wasserunlösliche Kristalle und gehört als chemischer Kampfstoff zu den Nasen- und Rachenreizstoffen (Sternutatoren). Die Aufnahme erfolgt als Aerosol in Aceton. In Dampfform wird die Reizschwelle von 0,00038 mg/l Luft nicht errei
Beschreibung
Adamsite (DM) was first synthesized in 1915 by a German chemist Heinrich Wieland, and again in 1918 by a US chemist Robert Adams who named it adamsite. DM is a yellow-green, odorless crystalline solid at room temperature with low volatility. It is insoluble in water and relatively insoluble in organic solvents.
Verwenden
As war gas, dispersed in air in the form of minute particles. For riots in combination with tear gas (chloroacetophenone). In the formulation of wood-treating solutions, against marine borers and similar pests.
