Toxic Substances 



• Carcinogenicity and toxicity of fi- 

 brous ampiiiboles 



• Biochemical methods for screening 

 organic and inorganic pollutants 



• Epidemiological research on correla- 

 tion of cancer and other chronic dis- 

 eases with environmental pollution 



• Biological monitoring and tissue ar- 

 chiving 



Ecosystems Research 



• Measurement of overall pollution 

 stress and impacts of single and 

 complex stresses 



Environmental Processes and Systems 



• Predictive exposure assessment meth- 

 odologies for existing and new organic 

 and inorganic chemicals and nutrients 



Water Quality Models 



• Heavy metals, including mercury 



• Persistent and highly volatile pesti- 

 cides 



• Nonpoint source loading models 

 coupled to basin water quality mo- 

 dels 



Industrial Processes Program 



• identification and control of air pollu- 

 tion problems 



• Hazardous waste disposal (closed- 

 cycle systems) 



• Water industrial processes 



Monitoring and Technical Support Pro- 

 grams 



• Alternate methods and products for 

 measuring pollutants in industrial and 

 municipal effluents 



• Agencywide laboratory automation 

 system (this technology is of particu- 

 lar importance to monitoring labora- 

 tories that must analyze large num- 

 bers of samples accurately to support 

 enforcement actions). 



List of Gap Areas 



• Growth and concentration of popula- 

 tion. (Although EPA does not for- 

 mally adopt 10-year goals, its sub- 

 mission stated that "population as- 

 pects of the environment will be a 

 major new area of research.") 



National Aeronautics and Space 

 Administration (NASA) 



The basic research of NASA must be relevant 

 to NASA mission objectives for aeronautical and 

 space activities. 



List of Priorities (short-term) 



Physical Sciences 



• Planets, comets, asteroids, stars, 

 nebulae, galaxies, quasars, and other 

 sources of radiation in all wave 

 lengths, with emphasis upon gamma 

 ray, x-ray, cosmic ray, visible 

 sources, and UV and IR spectrosco- 

 py 



• Interaction of the solar wmd and the 



magnetosphere 



• The interplanetary medium 



• Nature of solar variability 



Environmental Sciences (Planetary) 



• Venus' atmosphere and gravitational 

 character 



• Jupiter. Saturn, and their environ- 

 ments by acquisition of imaging, 

 fields and particles, and composition 

 data 



• Mars via continued analysis of data 

 from Viking and other missions 



Environmental Sciences (Earth) 



• Remote sensing for identifying and 

 monitoring pollutant species in the 

 troposphere and water bodies, espe- 

 cially for all-weather and day and tiight 

 conditions 



• Remote sensing research on monitor- 

 ing the physical parameters of the 

 ocean surface using active and pas- 

 sive microwave radars 



• Research into features of severe 

 storms most readily identified by 

 remote sensing technology 



• Preliminary models of crustal in- 

 homogeneities based on tectonophys- 

 ics, magnetic field, and gravity field, 

 etc. 



• Composition and structure of the up- 

 per atmosphere 



Life Sciences 



• Physiological changes in man and 

 other organisms in a gravity-free 

 environment 



• Search for extraterr2strial life 



Engineering Sciences 



• Fundamental knowledge of fluid 

 mechanics and aerodynamics
