[Poisoning with leather-impregnation sprays. A retrospective analysis of 224 cases of poisoning]

Annually, there are about 100-200 intoxications in the Federal Republic of Germany caused by inhalation of leather impregnation sprays. The course of these intoxications is moderately severe in 60% and severe in 18% of the cases. The signs and symptoms are characterized by a respiratory distress syndrome which sets in about 15-60 min after spraying and which requires several days of hospitalisation in severe cases. The sprays contain about 7-11 components; their toxicity is not exclusively associated with one substance only. Lower toxicity can be achieved by preparing a basic formulation adjusted to the low-hazard components.
