Hydrogen cyanide is a product of combustion of synthetic polymers, wool and silk; additionally, it is produced during the combustion of fuels in automobile engines as a result of catalytic reduction of nitrogen oxides. However, the concentration of HCN in the exhaust gas is higher only in the absence of catalyst (Karlsson and Botz 2004 ).

In conclusion, we suggest that cyanide itself could have a signaling role. Indeed, cyanide has been proposed to act as a regulator of several biological processes4 and besides its pos-sible role as a ROS producer for signaling purpose, a direct effect of cyanide as signaling molecule cannot be discarded.
