A survey is presented on the research and development needs for personal monitoring devices for toxic organic compounds in the ambient atmosphere. This survey includes a description of organic compounds and their ambient concentrations, individual compounds of high priority, a summary of a literature survey, a description of commercially available samplers, a summary of recent developments in ambient personal monitoring and recommendations on major research needs. The high priority compounds identified were: methyl chloride, dichloromethane, benzene, carbon tetrachloride, chloroform, dichlorobenzenes, 1,2-dichloroethane, methyl chloroform, trichloroethylene and perchloroethylene. The literature survey covers the period, 1974-79. Commercially available personal samplers described are Dupont's Pro-Tek organic vapor badge, Abcor's gas badge, 3-M's organic vapor monitor and the Minimonitor (P.W. West, Louisiana State University). Recent activities include a description of an EPA sponsored program at Monsanto Research Corporation on development of personal samplers for organics. A description is also given of several recent field studies on sampling and analysis for benzene and chlorinated hydrocarbons. The survey concludes with recommendations for research and development activities in the following areas: evaluation of sorbent materials, development of analytical techniques based on electron capture-gas chromatography, evaluation of available active and passive samplers, development of passive samplers and development of standard mixtures for evaluation of personal exposure devices.
