Lewisite laboratory tests

There is no specihc laboratory test for Lewisite. Lfrinary arsenic excretion might be helpful. Hemolytic anemia may be seen in Lewisite exposed patients. 

There is no specific laboratory test for Lewisite. Urinary arsenic excretion might be helpful in identifying possible exposure to Lewisite, however. Patient Management... 

Signs and symptoms of acute lewisite exposure include a rapid onset of irritation to the eyes and mucous membranes of the upper respiratory tract (lachrymation and rhinitis). In more serious cases of vapor intoxication, chest pain, nausea, vomiting, headache, weakness, convulsions, hypothermia, and hypotension occur (Sidell et al., 1997 Katos et al., 2007). Laboratory tests of the blood of persons exposed may show hemoconcentra-tion animal studies suggest elevated liver enzymes, including lactate dehydrogenase (LDH) (King et al., 1994 Sasser et al., 1999). The following sub-sections describe the effects on specific body sites. 

Special Chemical laboratory hoods will have an average inward face velocity of 100 linear feet per minute (lfpm) 20% with the velocity at any point not deviating from the average face velocity by more than 20%. Existing laboratory hoods will have an inward face velocity of 150 lfpm 20%. Laboratory hoods will be located such that cross drafts do not exceed 20% of the inward face velocity. A visual performance test using smoke producing devices will be performed in assessing the ability of the hood to contain Lewisite. 

Twenty-five laboratories participated in the sixth official proficiency test where lewisite 1 (CAS 541-25-3) was used as spiking chemical in the organic liquid sample. Five of the seven laboratories that performed sample preparations to derivatize the... 

One day I was taken for a jeep ride over the testing field. We passed a twisted metal object with liquid in its concave portion. The soldier driver steered clear of it and said it was the remains of an air-drop bomb and the liquid was residual war gas. It was December and quite cold. The laboratory crew told me about a big experiment Dugway had recently performed. The Army shaved the wool off the backs of a flock of sheep, and in an area remote firom the headquarters built a fence to contain the sheep. Aircraft flew overhead at an unspecified elevation and sprayed a large amount of Lewisite (one of the World War I persistent gases). The sheep were examined but showed no damage. Apparently, the Lewisite evaporated before reaching the ground.
