ABSTRACT:
Oily hydrocarbons which pollute the surface of water are removed therefrom by scattering over the polluted surface solid particles of nutrient salt containing nitrogen and phosphorous in a form that is readily assimilable by aqueous microorganisms capable of metabolizing hydrocarbons. The particles of nutrient salt are given a surface pretreatment with paraffine so that they are buoyant and only slowly soluble in water and lipophilic.
