Methods and Systems for Monitoring Airborne Contaminants using Atmospheric Condensate

Rolf Halden (Inventor)

Research output: Patent

Abstract

Indoor air pollution has been identified as being among the top five environmental health risks. Air contaminants stem from both the components of the building itself and human activities and natural conditions in and around the building. There are a multitude of indoor environments that require air pollution monitoring - ranging from aircrafts and submarines to commercial buildings and storage units. Current methods to sample and monitor air contaminants are expensive, difficult to use for those not trained in the field, and intrusive to the area they monitor. Researchers at Arizona State University have developed a novel system that can easily, economically, remotely, and rapidly monitor the air quality of closed or semi-closed environments. This system can qualitatively and quantitatively assess the air quality in all buildings or environments, particularly those with HVAC duct work or an air recirculation system. The process is cost effective and sampling and monitoring can be performed by non-technical personnel as the system does not require specials skills or training. Moreover, real-time sensors can be utilized to enable early warning/immediate response mechanisms. This technology represents a novel and viable process that can effectively capture indoor air pollution in an effort to monitor contaminants where air quality may be of concern. Potential Applications Environmental and Occupational Health: Monitoring of environments with centralized ventilation and/or limited ventilation including submarines, aircrafts, malls, mines, homes, etc. Monitoring of environments with significant sources of contamination including storage units, homes close to industrial sites, etc. Law Enforcement Monitoring structures to screen for illicit drugs, explosives, bioterrorism agents, etc. Homeland Security Monitoring of aircraft cabins or other environments for hazardous substances including biological, chemical and radiological agents (viruses, weaponized bacterial strains, toxins, toxicants etc.) Benefits and Advantages Cost-effective - can be implemented on units already present in subject environment Ease of use can be sampled and monitored by non-technical personnel can provide either time-averaged or time-discrete data Remote monitoring - technician does not have to be on site Non-intrusive/covert - the system can be hidden Rapid monitoring Dowload Original PDF For more information about the inventor(s) and their research, please see Dr. Halden's directory webpage Dr. Halden's laboratory webpage
