Abstract
On 20 March 1989 a very severe accident occurred at a chemical plant n ear the town of Ionava in Central Lithuania. We have estimated the atm ospheric dispersion of ammonia released in the accident, focussing on the possible long-range effects. The computations were made using traj ectory and dispersion models based on gradient-transfer diffusion theo ry, using actual meteorological data. The computed concentrations were compared with available observations, obtained from the European Moni toring and Evaluation Programme stations.
