Basically, the best way is to combine possible ways of cleaning oil spill. In the long term damage to ecosystems from oil spills is minimal. Recovery is faster if you let the oil dispersed naturally. Bacterial decomposition of hydrocarbons, which contributes to the destruction of a continuous film by the wind and waves, in warm and temperate climate is completed in 3-4 years. In cold climates, such as in Alaska, where in 1989 crashed tanker «Exxon Valdez», the negative effect lasts longer because of reduced bacterial activity. Application of surface-active dispersing agent accelerates the process, but these substances are often exacerbated environmental damage because the toxic and difficult to biodegrade. The results showed that the discreet but constant leakage of petroleum products, such as coastal refineries and terminals, dangerous to the marine and intertidal ecosystems than capture of headlines of major accidents.
