A growing body of research is pointing to the possibility that the Earth’s oceans contain far more mercury than previously thought.
The International Institute for Applied Systems Analysis, a research group based in the United Kingdom, has produced a report based on data from the first comprehensive study to assess mercury concentrations in the oceans of some of the world’s most populous countries.
The team looked at data from more than 4,300 measurements of mercury concentrations taken in the past two decades from a number of global monitoring sites and found that in countries that have high levels of mercury pollution, it is spread out over a wider area than in those that have low levels.
The group found that the total concentration of mercury in the world ocean is 0.7 percent higher in some countries than in others, which is around twice the global average.
The researchers did not calculate the spread of the levels of the contaminant, but said it could be a factor of three to five times higher than previously estimated.
It is estimated that the mercury in ocean water contributes to the amount of mercury released into the atmosphere.
This amount of pollution is estimated to have caused an estimated 1.7 billion premature deaths worldwide between 2007 and 2020.
The report said the number of people affected by the mercury pollution could be as high as 2.5 billion.
According to the World Health Organization, around 2.8 billion people are currently living in countries where there is high levels or near-high levels of pollution, which means there are around three times as many deaths as in countries with low pollution.
The researchers also looked at the level of mercury concentration in the surface waters of the oceans, which they calculated could be between 4 and 7 percent higher than that measured by the global body of water.
The study, which was released today, was published in the journal Science.
The findings come at a time of increased awareness of the health risks of mercury contamination in the ocean.
In the U.S., there is a long-standing public health campaign to limit the levels and sources of mercury that are released into our oceans, including from fish farming and industrial activities.
Mercury is toxic, but it is found in fish and other marine life.
The world’s oceans are rich with many species of fish that are important for humans to eat.
The team said that the increased concentration of fish mercury in global oceans was linked to a number the species are not able to eat at a sustainable rate.
The mercury concentrations are higher than in fish from many other regions, but the researchers found that there is no correlation between the levels found in the Atlantic and Pacific oceans.
The Pacific is the main region for fish consumption in the U
