The article shows examples of using the algorithm for calculating emissions into the atmosphere during production activities in the process of laboratory tests for designing maximum allowable emissions and assessing the impact of possible activities on the environment. The calculation algorithm is based on the use of the ERA PC software package in the laboratory process, designed to calculate pollutants in all components of the environment. This software package allows you to make calculations for many parameters automatically, which simplifies the work of environmental designers. The use of this software package can be used in the training of specialists in the field of environmental monitoring.
