A system for washing the air in a coastal environment in which a volume of air moves from a land mass to a water mass. The system includes a plurality of fountains 12 mounted offshore which spray a volume of water into the path of the air flow. Water is stored under pressure and selectively released to form the spray. In specific embodiments, wave motion is used to provide the power to pressurize the stored water. Wave power is extracted by dual reciprocating pumps 50 and 51 connected to a float 40. Wave power is amplified by lenses 20 which focus the waves onto the floats 40. A control system 100 senses pollution and controls the generation of the spray. In addition, wave motion is sensed and used to control the position of the lens 20 for optimum performance and minimum wear.

Apparatus and methods for identifying the nature of an unidentified substrate present in trace amounts of known gaseous or liquid media such as air or water include collecting a sample of the substance in the media, filtering and concentrating the sample, depositing at least a portion of the same on a known substrate, analyzing the deposited sample utilizing SETM, NFOM and/or AFM techniques to form one or more images characteristic of the unidentified substance, and then identifying the substance by comparing the images so obtained to images of known substances obtained using the same techniques.
