Pulmonary toxicants militarized as chemical agents,_____and________were the earliest agents employed in WWI. Exposure to this class of chemical agents called ______ agents have painful local effect on sensitive human tissues . Sulfur mustard and______mustard . sometimes called mustard gas Are in the class of chemical agents _____. In another chemical agents agents called _____agents are not intended to be lethal but can be under some circumstances. Another class of chemical agents _____agents cause damage to red blood cells However this symptompatic classification is not a technical description because agents grouped in this class do not all function by similar _____ mechanisms . Very toxic ____ agents are organophophorus compounds mostly phosphate esters which interfere with___ enzymes causing convulsions and death by respiratory paralysis. The evaporation rate of an agent is inversely related to the ____of a chemical agent a property important to the operational effectiveness . As the temperature increases the evaporation rate of an agent ____. Persistance depends on temperature dependent molecular properties . the enthalphy of vaporization that determines the vapour ____ near the liquid surface and the ______ that determines gaseous diffusion rate at a given temperature .The change in evaporation rate with temperature can be calculated by the knowledge of ____ for the chemical agent through the clausius clapeyron equation . The rate limiting step in agent evaporation from the liquid is molecular diffusion transport through thin surface____ For unprotected personnel_____,is the most vulnerable portal for airborne chemical agents. The most effective and fastest acting agents enter by inhalation of_____that are absorbed by high surface area_______Mobility of low molecular weight agents across biomembranes by intracellular diffusion is moderately fastexcept for two types of dense cellular membranes____:and_______The rate of absorption of agents through biological membranes by passive diffusion is greater for smaller chemical agents that are., ____one measure of which is Kow. The_____Convention is a______that prohibits production, stockpiling,and use of chemical weapons, chemical agents and their ________establishes production and use prohibitions and controls listing specific controlled chemicals on three_______Export of chemical agents and precursors and molecules having similar _________on all three lists are prohibited to States not agreeing to the convention The _____and______are the most serious TIC threat against people in confined space because of their _____perceptility and very high toxicity and rise of dispersion.
