The data illustrate the pollution that contained some part in the ocean in periods of 1997 to 2001.
Overall, 71% particles in the sea had slightly decreas over one decade, for example air pollutans, farm waste, industrial waste, marine and litter with industrial waste gain the biggest changes in intire periods. Altought there still 29% left for the pollutans to increase, such as Domestic sewage and offshore oil, which has more number of rise than other.
It is clearly saw in the 1997 pollutans from air held the most part of the pollution in ocean which is 30%. Otherwise, in the last period, pollutans from air has equal percentage with domestic sewage due to the slightly fall for air pollutans and the significantly soar by domestic sewage from 18% to 29% in ten years.
In addition Indurtial, marine and offshore were in the mid position in the percentage of ocean pollution. While Indurtial waste and marine were similary decline for 8% and 9%, the offshore oil increased 9%. Not to mention the farm waste and litter were the least percentage of the whole particles of pollution in the sea
