Hokkaido University scientists show that under laboratory conditions, ultraviolet light reacts with nitrophenol to produce smog-generating nitrous acid. An advanced laser technique has allowed ...

Nitrous acid can initiate photochemical air pollution events, but it is not clear where it comes from. Laboratory experiments now suggest that surface-bound nitrite accumulated overnight can release ...

Nonsmokers may have a new worry—thirdhand smoke. Nicotine residues on indoor surfaces can react with nitrous acid in the air to form carcinogenic nitrosamines not present in fresh tobacco smoke, ...
