REVIEW OF PAPERS PUBLISHED IN 1985 ABOUT EMISSION, TRANSPORT, TRANSFORMATION AND DEPOSITION OF ATMOSPHERIC TRACE CONSTITUENTS OF IMPORTANCE FOR ACID DEPOSITION.

About 300 papers published in 1985 or late in 1984 have been reviewed. There has been progress in the development of models for acid deposition and photochemical oxidants. Simultaneous measurements of O3, NOx, individual hydrocarbons, aldehydes, CO and OH have lead lo the conclusion that the atmospheric gas chemistry in moderately polluted air is well understood. There is an upward trend over Europe in the concentration of methane, CO and 03.
