ST. PETERSBURG, Russia (AP) — Russian investigators have opened a criminal case after finding pollution levels in a local river far exceeded norms, with ethyl alcohol levels charted at 5,400 times the acceptable limit.
This was just one of several indicators reported Friday by the North-Western Transport Investigation Department that the Novaya river in St. Petersburg is over-polluted.
Investigators found high levels of butyl alcohol, isopropanol, and acetone as well as ethylene glycol. These chemicals are flammable, solvent or used in anti-freezes and can be toxic.
Regional authorities recently filed a case against the local Pulkovo airport to cease sewage runoff into nearby rivers and canals. Officials believe the airport is responsible for high levels of harmful substances.
