Portable air sampling apparatus and methods are provided forpassively and/or intermittently sampling air in the breathing zoneof a person over extended periods of time. The presence of airbornecontaminants can be monitored, as well. Air sampling systemperformance can be continuously measured and recorded within a datalogger. In addition, physical activity levels of a person wearing aportable air sampling system can be continuously monitored andrecorded within the data logger. An input device communicates withthe data logger and allows a user to store information about his orher personal activities in the data logger. A receiver incommunication with the data logger can receive data from remotelylocated communications devices, such as a Global Positioning System(GPS) signals. A transmitter in communication with the data loggercan transmit data from the data logger to remotely locatedcommunications devices.
