News Section
Sources of man introduced lead into the environment, transfer pathways and abatement technologies; Analytical methods and monitoring of environmental lead. The discussions will be centered mainly on the subclinical effects and on the organization of the protection of man and his environment. The Symposium is of particular interest for experts in environmental protection and for all those interested in ecological and health aspects of environmental pollution. Scientific papers of about 30 min may be submitted in English, French or German. Simultaneous interpretation will be provided in these languages. The proceedings of the Symposium, including the full discussions will be published. No registration fee is required. The participants will have to pay their hotel and travelling expenses; they should also take care of their hotel accommodations. A ladies’ programme of visits and excursions will be organized. Registration: Papers : Secretariat :
Participants should register not later than 1 July 1972. Participants wishing to submit a paper are requested to send the title and two copies of the summary between 300 and 400 words in one of the languages of the Symposium, not later than 1 May 1972.

ON MEETINGS
WMO W/G on Atmospheric Pollution and Atmospheric Chemistry Within the World Meteorological Organization, the Commission for Atmospheric Sciences has a Working Group on Atmospheric Pollution and Atmospheric Chemistry. This W/G met in Geneva 11-15 October 1971, and its discussions may be of interest to readers of this journal. Those in attendance included Dr. R. E. MUNN (Chairman) of Canada, Dr. A. E. J. EGGLETONof the United Kingdom, Mr. L. FACY of France., and Mr. D. H. PACK of the United States. The other member, Dr. F. H. SCHMIDTof the Netherlands, unfortunately could not be present. The W/G was greatly assisted by the WMO Secretariat, particularly by Dr. E. DOBRYSHMAN, Mr. G. W. KRONEBACH, Mr. A. S. MANN and Mr. J. MARISSENS. Several days (and evenings!) were spent completing a WMO Technical Note on “Dispersion and Forecasting of Air Pollution”, which is now in press. The Table of Contents is as follows: (1) Introduction (2) Plume Rise (3) Transport and Dispersion in Non-urban Environments (4) Transport and Dispersion in Urban Environments (5) Forecasting for Air Pollution Applications Appendix: An Outline of Dispersion Methods used in the U.S.S.R. The W/G is indebted to Dr. F. GIFFORDof the United States, who prepared Chapter 4, and to Professor M. E. BERLYANDof the U.S.S.R., who prepared the Appendix. The WMO program to develop a network of regional and baseline air pollution stations was examined. Special attention was given to Part I of the WMO Operations Manual for Sampling and Analysis Techniques for Chemical Constituents in Air and Precipitation. The W/G was pleased with the progress made by WMO in the last 2 yr, and expressed the view that Part I of the Manual meets the requirements for guidance in the operation of a minimum program at regional air pollution stations. Four items that require special attention in the immediate future were suggested: (a) Research studies to determine optimum network density criteria for regional air pollution stations ; (b) Research studies of monitoring methods to be used on ships and at shoreline stations, where sea spray may create problems, particularly in the case of precipitation chemistry analyses;

(c) Standardization of monitoring methods to be used to sample the upper troposphere and lower stratosphere; (d) Research studies to ascertain quantitative estimates of the fluxes of pollutants to and from the atmosphere to the oceans and to vegetation. Although such information is urgently needed to estimate regional and global budgets of various pollutants, the W/G felt that the state-of-the-art has not yet reached the stage where monitoring networks for vertical fluxes could be established. It was recommended that WMO Member Countries be encouraged to carry out research studies on monitoring problems. The W/G agreed to undertake an inventory of stable gases that might be suitable as atmospheric tracers for experimental studies of distant diffusion. Dr. EGGLET~Noffered to assume the initial responsibility for this task, including information on costs, background concentrations and detection limits. Finally, the W/G expressed the view that there was a need for an additional Technical Note dealing with the chemistry of the transformation of pollutants and their removal from the atmosphere. These matters are briefly discussed in the Technical Note now in press, but much more elaboration is desirable. Dr. EGGLETONagreed to prepare an outline for such a Technical Note and to suggest authors for the various chapters. A target publication date of 1974 for this second Technical Note is suggested. R.
