  In this work it is shown that, in contrast to the strong and electromagnetic
theories, additive conserved numbers (such as lepton, aromatic and another
numbers) and gamma-5 anomaly do not appear in the standard weak interaction
theory. It means that in this interaction the additive numbers cannot be
conserved. These results are the consequence of specific character of the weak
interaction: the right components of spinors do not participate in this
interaction. The schemes of violation of the aromatic and lepton numbers were
considered.
