Tyre Wear Particles Focus Tyre Toxicity Issue
The Tyre Industry Project, the cooperative group of tyre manufacturers that addresses common industry issues across the tyre sector has been, for some time, investigating how it can address issues related to tyre wear particles, which end up in the soil and in the waterways and oceans as microplastics. We have seen issues related to Quinone 6PPD, a derivative of an additive to tyre rubber ...

Greenland’s health ministry signs cooperation agreement with EEA
The Ministry of Health in Greenland has signed an agreement with the European Environment Agency (EEA). The two organisations committed to exchange personnel, and share knowledge, data and other expertise on environment-related health issues. The aim is to improve the sharing of data and information. Both parties hope that this will contribute to the quality and timeliness of assessments of ...

Melting glaciers free trapped pollutants
Melting glaciers in the Swiss Alps are releasing pollutants that have been frozen in the ice for decades. A recent study suggests that by accelerating global ice loss, global warming is likely to increase environmental contamination with persistent organic compounds that are no longer widely used, such as PCBs and DDT. Persistent organic pollutants are chemicals that can travel long distances in ...

With three new reference materials, NIST gets the dirt on soil
The National Institute of Standards and Technology (NIST) has issued three new certified reference materials for soil. Intended for use as controls in testing laboratories, the new Standard Reference Materials (SRMs)—gathered from the San Joaquin Valley in California and from sites near Butte and Helena in Montana—will aid in determining soil quality, detecting soil contamination, and monitoring ...

New Jersey Waters Fall Short of State Standards
TRENTON, New Jersey (ENS) - Many waters in New Jersey are not meeting state water quality standards for aquatic life, fish consumption and freshwater recreational uses, according to a new comprehensive report issued today. Still, most waters in the state are healthy enough to support drinking water supply, shellfish harvesting, and ocean beach recreational uses, the report concluded. The ...

ASTM G91 - 11 Standard Practice for Monitoring Atmospheric SO2 Deposition Rate for Atmospheric Corrosivity Evaluation
Atmospheric corrosion of metallic materials is a function of many weather and atmospheric variables. The effect of specific corrodants, such as sulfur dioxide, can accelerate the atmospheric corrosion of metals significantly. The sulfation plate method provides a simple technique to ...

Microplastic particles in North Sea could harm marine organisms and enter human food chain
Researchers have discovered high levels of plastic particles and fibres, as well as black carbon (BC), which is formed by the incomplete burning of fossil fuels, in the waters of the Jade Bay, an inshore basin off the coast of Germany in the Southern North Sea. The concentration of suspended particles are of concern because they have the potential to be ingested by fish and other marine life, and ...

Public Invited to Comment on Revised Plan to Reduce Nutrients from 31 States to Mississippi River
Public Invited to Comment on Revised Plan (see PDF in Articles section) to Reduce Nutrients from 31 States to Mississippi River. The Gulf Hypoxia Task Force, chaired by EPA, has just released its 2008 revised Gulf Hypoxia Action Plan that identifies efforts to track progress, update the science and adapt actions to reduce nutrients flowing from 31 states into the Mississippi River. Those excess ...

Environmental education award presented to old town, me teacher
Ed Linsdsey, a teacher at Old Town High School, was recently awarded the President's Innovative Award for Environmental Educators (PIAEE). Mr. Lindsey is one of two teaches selected to receive this award in EPA’s New England Region. As discussed in the "America's Great Outdoors: A Promise to Future Generations" report, in order to make environmental stewardship and conservation relevant to ...

How valuable are satellite observations of seawater quality?
Global Earth Observation (GEO), such as satellite observations, helps manage environmental resources and prevent disasters. However, they are expensive. A recent study proposes a framework to assess the value of GEOs in which stakeholders are consulted. GEO consists of all observational information about the state of the world, including satellite observations and 'in situ' information. Many ...

EPA Everglades Study Shows Contamination has Declined, but Risks Still Remain
(ATLANTA – September 19, 2007) The U.S. Environmental Protection Agency released a report today documenting the ecological condition of the entire 2,063-square-mile freshwater portion of the publicly- owned Everglades. The report documents the third phase of an 11-year study of the Everglades marshes, which determined that mercury in prey fish is declining, but still elevated, while phosphorous ...

Europe still playing catch-up on air pollution, despite reduction successes
The European Union appears to have met several objectives to reduce the impacts of air pollution, according to the original scientific understanding used to set the objectives. But when using the improved scientific understanding of air pollution now available, it becomes clear that emissions need to be even further reduced to protect health and the environment. The European Environment Agency ...

Historic agreement on improving Lake Tahoe clarity signed by California and Nevada governors
U.S. Senator Dianne Feinstein today hosted the 15th Annual Lake Tahoe Summit, at which California Governor Edmund G. Brown, Jr., Nevada Governor Brian Sandoval and U.S. EPA Regional Administrator Jared Blumenfeld signed a roadmap to return the lake to almost 100 feet of clarity within 65 years. The water clarity of Lake Tahoe declined from a visibility level of 105 feet in 1967 to an all time ...

Greenland ice core reveals history of pollution in the arctic
New research, reported this week in the online early edition of the Proceedings of the National Academy of Sciences, finds that coal burning, primarily in North America and Europe, contaminated the Arctic and potentially affected human health and ecosystems in and around Earth's polar regions.The study, titled 'Coal Burning Leaves Toxic Heavy Metal Legacy in the Arctic,' was conducted by the ...

Study reveals mercury contamination in Fish Nationwide
Scientists detected mercury contamination in every fish sampled in 291 streams across the country, according to a U.S. Geological Survey study released today. About a quarter of these fish were found to contain mercury at levels exceeding the criterion for the protection of people who consume average amounts of fish, established by the U.S. Environmental Protection Agency. More than two-thirds ...

Reduced heavy metals and nitrogen in mosses reflect falling air pollution across Europe
Deposition of heavy metals and nitrogen is falling across Europe, a new study suggests. The researchers used the levels of these pollutants in mosses as indicators of how deposition has changed from 1990 to 2010. These reductions are likely to be the result of effective air pollution policies, they say. Heavy metals, such as lead and cadmium, can be toxic to both humans and wildlife, and ...

New insight on the spread of contamination from Fukushima
A study on the transport of radioactive isotopes from Fukushima in the two months after the nuclear incident suggests that they were at official levels of contamination for 34,000 km2 of Japan, and that 2.8% of iodine radionuclides from the event were calculated to have reached the EU. The 2011 nuclear accident at Fukushima, Japan, caused the release of large amounts of radionuclides (unstable ...

IONICON PTR-TOF-MS helps providing new insights and a SCIENCE paper
J.-H. Park et al. were relying on an IONICON PTR-TOF 8000 instrument to study fluxes of an unprecedented number of volatile organic compounds (VOCs) simultaneously. Their results, “Active Atmosphere-Ecosystem Exchange of the Vast Majority of Detected Volatile Organic Compounds“, have recently been published in the prestigious SCIENCE Magazine. Using traditional measurement techniques, ...

Landmark US Geological Survey study demonstrates how methylmercury, known to contaminate seafood, originates in the ocean
A new landmark study published today 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 ...
