[To the substantiation of the maximum allowable concentrations of the herbicide dalzlak-T in ambient air].

The paper presents the results of experimental studies of the reflectory and resorptive effects of different concentrations of the herbicide Dalzlak-T in ambient air. Hygienic regulations have been first developed and a hazard class for the agent has been defined to estimate ambient air pollution during its manufacture, storage, transportation, and agricultural application.
