DEFENDING THE U.S. AIR TRANSPORTATION SYSTEM AGAINST CHEMICAL AND BIOLOGICAL THREATS... 

Determine unique air transportation requirements for dealing with chemical/biological threats and coordinate closely with other agencies that are active in the chemical/biological threats area to ensure that these requirements are given visibility in their programs. 

As suggested by the wording of the topic of this report in the list above, this study is concerned not only with technologies for detecting the presence of chemical or biological threat agents in the air transportation context, but also with... 

For biological threats, enviromnental transport will result in the exposure of populations of various organisms to the threat. These populations can provide a mode for subsequent long-term transport of the threat. This is a particular concern for zoonoses, diseases that normally exist in wild animals but are transmissible to humans. The populations of interest may include host or reservoir species, such as birds, mammals, reptiles, or humans, and vector species, such as arthropods. This chapter accordingly considers the use of models to understand the interactions between biological threats that have become established in natural host populations and human populations. Approaches for placing these models in a spatially explicit context in order to predict transport are also discussed. 

Environment is the natural environment (weather, climate, ocean conditions, terrain, vegetation, space conditions) combat environment (dust, fog, nuclear-chemical-biological) threat environment (effects of existing and potential threat systems to include electronic warfare and communications interception) operations environment (thermal, shock, vibration, power variations) transportation and storage environment maintenance environment test environments manufacturing environments (critical process conditions, clean room, stress) and other environments (e.g., software engineering environment, EM) related to system utilization.
