Toxic contamination in Russia`s Neva river

A Greenpeace study in St Petersburg, Russia, says 40 per cent of the city's waste is dumped into the Neva river due to shortage of waste treatment facilties. And this has been contaminating fish stock, which is sold in markets. The study found that pollutants from untreated and industrial waste included arsenic and polychlorobiphenyl, which is a lethal organic pollutant. Also, levels of copper in the city's main waterway have crossed the accepted norm by 73 times and levels of manganese, by 26 times.
