Help me to find some mistakes, please. A method of quantitative assessment of the marine environment of pollutants from the bilge waters of ships was developed. The contribution of shipping and marine oil extraction to the pollution of the Barents and White seas by heavy metals and oil hydrocarbons was estimated. According to calculations, about 1.5 tons of oil is annually supplied to the Barents and White seas from the bilge waters, which is less than previously estimated. Oil losses during oil loading operations are estimated at 1200-6500 tons per year, leaks in oil production-less than 1 ton per year. The amount of heavy metals, nitrogen compounds, surfactants entering the seas annually with the bilge waters of ships varies for various pollutants from several tens of grams to 10 kg. Thus, the bilge waters of ships are not a significant source of pollution of the Barents and White seas. The contribution of shipping to marine waters pollution by oil hydrocarbons due to losses during oil loading operations is noticeable. Routine operation of vessels and oil platform "Prirazlomnaya" under conditions of strict compliance with the environmental standards of navigation, control of cargo leakages and no accidents will not have a significant impact on the quality of waters of the Barents and White seas.
