Detection limit determination for Tekran 2700
The new Tekran 2700 Methyl Mercury Auto-Analyzer continues to exceed the performance specifications it was designed to meet. We have established that the unit is capable of sample runs times below 8 minutes. With our all new electronics platform and advanced optics, we have reached even lower sensitivity levels. Using the EPA 40 CFR 136 protocol, we have determined the method detection limit ...

Economic benefits from reducing mercury emissions
Large benefits can be achieved for society by reducing global emissions of mercury. Global savings of US$1.8-2.2 billion (€1.3-1.6 billion) can be made by reducing damage to IQ alone, according to recent research. Mercury emitted to the atmosphere primarily comes from combustion of fossil fuels (about 46 per cent of global mercury emissions) and high temperature processing of minerals, such as ...

Bacterial genes involved in making toxic methylmercury are identified
Research into mercury has identified two genes in bacteria that appear to be required for turning the metal into its most toxic form, methylmercury. The study adds to a growing body of research that helps us to understand the transformations that mercury undergoes in the environment and the microbes involved in these transformations. Mercury is harmful to animals and humans and its more toxic ...

Mercury Hotspots Detected in Eastern U.S. and Canada
WASHINGTON, DC (ENS) – U.S. sources of mercury emissions, particularly coal-fired power plants, are the major cause of five biological mercury hotspots identified in New England, New York and Nova Scotia, according to two new scientific studies. The findings indicate the U.S. Environmental Protection Agency, EPA, is greatly underestimating local and regional impacts of mercury emissions, but ...

Forest fires increase mercury emissions
Mercury is a global pollutant arising from many sources, including biomass burning (BMB), which includes both wildfires and intentional fires to clear land. A recent study estimates that mercury emissions from BMB make up 8 per cent of total global mercury emissions. Mercury emissions from BMB have received growing attention. Forests in particular act as mercury sinks because atmospheric ...

GM bacteria may mop up mercury more efficiently
Using genetically modified (GM) bacteria may be a cheaper and easier way to clean up waterways contaminated with one of the most toxic heavy metals, mercury, according to a study. Mercury emissions are rising globally, largely from coal-fired power stations, waste incinerators, and the mining of gold and silver in developing countries — where millions are affected directly through mining ...

Mercury conference to address global treaty implementation
The International Conference on Mercury as a Global Pollutant (#ICMGP) will take place in Edinburgh, Scotland, from 28th July – 2nd August 2013. The event is the 11th in a series that began in Sweden in 1990 and follows closely behind an international agreement to reduce global mercury emissions. Themed ‘Science Informing Global Policy’ the ICMGP events have been created to ...

EPA Adds 12 Hazardous Waste Sites to Superfund’s National Priorities List
The U.S. Environmental Protection Agency (EPA) is adding 12 new hazardous waste sites that pose public health and environmental risks to the National Priorities List (NPL) for cleanup under the Superfund program. EPA is also proposing to add another eight sites to the list. Superfund is the federal program that investigates and cleans up the most complex, uncontrolled or abandoned hazardous ...
