[Environmental pollution with heavy metals at carrier rockets fall areas].

Based on hygienic monitoring, the authors evaluated environmental pollution with heavy metals at carrier rockets fall places and determined actual chemical load on environment.

[Hygienic evaluation of air pollution with aromatic hydrocarbons with reference to their transformation in the atmosphere of an industrial region].

A procedure was developed for air pollution monitoring, which takes into account the formation of secondary pollutants due to the transformation of initial noxious agents. The formation of chemical compounds for purposeful searches for aromatic hydrocarbon transformation products was predicted in the hygienic evaluation of air pollution. Atmospheric toluene transformation was shown to give rise to phenol and formaldehyde which in the presence of nitrogen dioxide are more toxic than toluene.
