An integrated collection and detection system is configured to monitor the ambient air for specific particles, such as toxins and pathogens. An air collector captures airborne particles and outputs a fluid sample including the captured particles in a fluid solution. The collection and detection system includes a control module configured to control the processing of the fluid sample such that detection of one or more types of particles is fully automated within the integrated system. The types of particles to be processed and detected include, but are not limited to, cells, bacteria, viruses, nucleic acids, toxins, and other pathogens. If one or more specific types of particles are detected, a system alarm is triggered. The system alarm triggers a local audio/visual alarm and/or is transmitted over a communications network to either a local or central monitoring location. More than one collection and detection system can be coupled to the network and monitored by the central monitoring location.
