Toxicologists in the Novgorod region in Russia's northwest have begun this year to identify previously undetectable impurities in the environment.
The newest gas chromatography used by employees at the regional state epidemic supervision centre has allowed them to establish the presence of ethyl-mercaptan and methyl-mercaptan in the air, as well as croton aldehyde in alcoholic drinks and acetic acid in construction materials.
