MOSCOW (Reuters) - Russia's environmental watchdog, Rosprirodnadzor, has noticed an increase in air pollutants to above permitted levels in Moscow coming from the area of the local region's oil refinery, the ministry for natural resources said on Tuesday.
On Monday an unpleasant smell was noticed in some parts of the city and an official with Moscow's Emergency Ministry was also quoted earlier by the Interfax news agency as saying that a malfunction at a Moscow refinery was to blame.
Gazprom Neft, which owns the refinery, said on Monday that the plant, the sole refinery in the Moscow region, was working normally.
It did not reply to a Reuters request for comment on Tuesday.
