PH3, NH3-PH3, and NH3-C2H2 photochemistry [7-13]. Furthermore, recent Galileo, Cassini, and Earth-based observations have better defined the abundance of key atmospheric constituents as a function of altitude and latitude in Jupiter’s troposphere. These new results provide an opportunity to test and improve theoretical models of Jovian atmospheric chemistry. We have therefore developed a photochemical model for Jupi- ter’s troposphere considering the updated experimental and observational constraints. Using the Caltech/JPL KINETICS code [14] for our photochemical models, our basic approach is two- fold. The validity of our selected chemical reaction list is first tested by simulating the laboratory experiments of PH3, NH3-PH3, and NH3-C2H2 photolysis with pho- tochemical “box” models.

Esswein, MSPH, CIH, CIAQP Senior Industrial Hygienist, National Institute For Occupational Safety and Health Nicola Erb Epidemiologist, National Jewish Medical and Research Center Acknowledgements: This project was sponsored, in part, by a grant from the Colorado Department of Public Safety and the United States Department of Justice through the Colorado Methamphetamine Program. In addition, the National Institute for Occupational Safety and Health provided a substantial amount of the laboratory analysis. The North Metro Task Force allowed us to sample at a number of their clandestine laboratory investigations and assisted in the Colorado Springs Police Department Sampling and the controlled manufacturing sampling. The Tri-County Health Department provided personnel and assistance during the sampling efforts and the Denver Police Department and Trinidad Police Department allowed us to conduct sampling at suspected methamphetamine laboratories within their jurisdictions. The Colorado Springs Police Department allowed us to conduct sampling during a controlled methamphetamine manufacture in their crime laboratory enabling us to test our sampling methodologies and to determine maximum chemical concentrations. Assistance was also provided by the Colorado Alliance for Drug Endangered Children and many of the emergency service agencies (police, fire, and EMS) in the Denver Metropolitan Area. The project personnel also wish to thank Lt. Lori Moriarty, Sgt. Jim Gerhardt, and Lynn Riemer for their help throughout the study.

Phosphine and Methylphosphine Production by Simulated Lightning
ARTICLE IN PRESS Atmospheric Environment 38 (2004) 6867–6874 www.elsevier.com/locate/atmosenv Phosphine and methylphosphine production by simulated lightning—a study for the volatile phosphorus cycle and cloud formation in the earth atmosphere Dietmar Glindemanna,b,Ã, Marc Edwardsa, Otto Schremsc aVirginia Polytechnic Institute and State University, 418 Durham Hall, Blacksburg, VA 24 061-0246, USA bInstitute of Animal Hygiene and Veterinary Public Health, University of Leipzig, Germany cAlfred Wegener Institute AWI, Bremerhafen, Germany Received 3 March 2004; accepted 23 August 2004 Abstract Phosphine (PH3), was recently found worldwide even in the remote atmosphere (Naturwissenschaften83(1996a)131; Atmos. Environ. 37(2003)24 29). It is of interest to ﬁnd natural mechanisms which could produce phosphine gas and drive a volatile link of the atmospheric phosphorus cycle and the formation of phosphoric acid as possible condensation nuclei for clouds. Here, we report on simulated lightning exposing sodium phosphate in a reducing medium (methane model atmosphere or organic matter) for 5 s to a spark induced by microwave. The gas product analyzed by gas À1 chromatography contained phosphine (yield up to 0.6 g kg phosphate P) and methylphosphine (CH3)PH2 (yield up to 0.02 gkg À1 phosphate P). We suggest a plasma-chemical formation mechanism where organic compounds or methane or secondary hydrogen thereof reduce phosphate to phosphine of which a small fraction can subsequently react with methyl radicals to form methylphosphine. A small yield of 6 mgphosphine per kgphosphate P was even obtained in methane free medium, by simple plasmatic recombination of inorganic phosphorus. We believe that methane and hydrogen are useful model substances of pyrolytic gases with high reducing power which may form if lightning strikes biomass, soil and aerosol.
