We studied the possibility of the combined application of screening models
to assess the characteristics of sources in accidents at storage facilities for hazardous
substances with complex models of atmospheric transport as part of modern
decision support systems to calculate air pollution in a wide range of spatial and
temporal scales. The evaporation time following an emergency spill, estimated by
screening models, is used to set the emission intensity and calculate the atmospheric
transport by the RODOS nuclear emergency response system. For the accident in
Chernihiv on March 23, 2022, it was estimated that the maximum permissible concentration
of ammonia 0.2 mg/m3 was exceeded at distances up to 75 km from the
source. The dependence of the calculated maximum concentrations on time is close
to asymptote 4.5
max
c t up to 15 h after emission, which is consistent with the asymptote
t 2 / 3 for the time dependence of the sizes of puffs following turbulent
dispersion of instantaneous releases.
