U.S. Geological Survey scientists say they've determined Pacific methylmercury contamination will increase 50 percent by 2050 if current rates continue. The researchers documented how mercury emissions from human sources make their way into the North Pacific Ocean, including the long-range transport of mercury within the ocean originating in the western Pacific Ocean. Methylmercury -- a highly toxic form of mercury -- can cause serious health concerns for those eating seafood, the scientists...

A new landmark study published May 1 documents for the first time the process in which increased mercury emissions from human sources across the globe, and in particular from Asia, make their way into the North Pacific Ocean and as a result contaminate tuna and other seafood. Because much of the mercury that enters the North Pacific comes from the atmosphere, scientists have predicted an additional 50 percent increase in mercury in the Pacific by 2050 if mercury emission rates continue as...

Citizens' groups say problem warrants immediate United Nations action WASHINGTON, Feb. 10 /PRNewswire-USNewswire/ -- As the world's governments convene next week to discuss developing a legally binding treaty on mercury, citizens' groups from around the world have released a new report calling attention to the significant global human health hazards caused by mercury in fish and fish-eating marine mammals. Over twenty groups from around the world (1), including the international Zero...

In a new study, researchers have reported that the mercury-based preservative thimerosal appears to be safe for use in children. The preservative was once used in infant vaccines to prevent the growth of bacteria and fungus, but has since become controversial due to purported risks that it is linked to autism. Use of the preservative in the US came to an end in 2001, except for certain flu shots.  Researchers in Italy studied thousands of babies who received two different types of...

Belgian scientists say they've found methylmercury, the main form of mercury found in the blood of marine mammals, might do more harm to seals than thought. Researchers led by Krishna Das of the University of Liege determined methylmercury, or MeHg, harms T-lymphocytes -- key cells in a seal's immune system. Similar results were also found for human lymphocytes. The researchers noted mercury exposure occurs both as a result of man-made pollution, as well as by natural events such as...

University of Michigan researchers have developed a new tool that uses natural "fingerprints" in coal to track down sources of mercury polluting the environment. The research is published in today's online issue of the journal Environmental Science & Technology. Mercury is a naturally occurring element, but some 2000 tons of it enter the environment each year from human-generated sources such as incinerators, chlorine-producing plants and coal-burning power plants. Mercury is deposited...

A recent study which will be published in February's edition of the journal Pediatrics proves that the form of mercury in vaccination preservatives can not be linked to autism, though some advocacy groups argue otherwise. Thimerosal, the preservative referenced in the study contains ethyl mercury. This allows the vaccines to be distributed in multi-dose containers. Prior to 1999 some scientists assumed that ethyl mercury and methyl mercury were similar, and that the health risks from the...

MADISON -The health risks posed by mercury contaminated fish is sufficient to warrant issuing a worldwide general warning to the public "” especially children and women of childbearing age-to be careful about how much and which fish they eat. That is one of the key findings comprising "The Madison Declaration on Mercury Pollution" published today in a special issue of the international science journal Ambio. Developed at the Eighth International Conference on Mercury as a Global...

By Andrew Stern CHICAGO (Reuters) - Mercury built into older-model U.S. vehicles will be removed before they are melted down for scrap under an agreement announced on Friday, putting a small dent in a worsening global environmental threat. Droplets of airborne mercury emitted by coal-burning plants, waste incinerators and from small-stakes gold mining operations circle the Earth for up to a year before descending in rainfall, contaminating waterways and converting to a toxic form...
