A gold speciation that adds a second layer to synergistic gold-copper toxicity in .

The metal-resistant bacterium occurs in metal-rich environments. In auriferous soils, the bacterium is challenged by a mixture of copper ions and gold complexes, which exert synergistic toxicity. The previously used, self-made Au(III) solution caused a synergistic toxicity of copper and gold that was based on the inhibition of the CupA-mediated efflux of cytoplasmic Cu(I) by Au(I) in this cellular compartment.

[Poisoning by hypochlorite-containing disinfectants. A retrospective analysis of 594 cases of poisoning].

Hypochlorite-containing disinfectants or bleaching fluids, if inhaled, may lead to life-threatening poisoning (56% of moderately severe cases, 5% of severe cases) through the immediate liberation of chlorine gas, if they are used together with another cleansing fluid which is very acid. A rough estimate suggests that there must be about 700 cases of such poisonings per year in the Federal Republic of Germany. The characteristic symptom is a respiratory distress syndrome when the liberated chlorine gas is inhaled.

[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.
