EPA releases new mobile source emissions model
WASHINGTON - An updated version of the Motor Vehicle Emission Simulator (MOVES) model – MOVES2010 – is now available for use to estimate air pollution from cars, trucks, and other on-road mobile sources. The model can also calculate the emissions reduction benefits from a range of mobile source control strategies, such as inspection and maintenance programs and local fuel standards. EPA will ...

New review of odour emissions modelling with model intercomparison
Dispersion modelling plays an important role in the assessment of potential odour annoyance for planned activities and the investigation of complaints related to existing facilities. However, compared to general air pollution modelling there are particular challenges associated with modelling odour dispersion and exposure due to the importance of odour variations over short timescales to the ...

8 states join forces to promote clean cars
Eight states, including California and New York, pledged Thursday to work together to dramatically multiply the number of zero-emission cars on the nation's roads by speeding the construction of charging stations and other infrastructure. The goal is to put 3.3 million battery-powered cars, plug-in hybrids and other clean-burning vehicles on the roads in those states by 2025. That's more than 15 ...

Hearing air pollution: sound art from WM-Air
Air pollution concentration data for the West Midlands (UK), modelled with CERC's ADMS-Urban model, have had new interpretations created by sound artist Robert Jarvis which are now available to experience online. Listeners can watch the variation of air pollution with synchronised audio based on the spatially and temporally varying concentration levels representing either an average daily cycle ...

New emissions certification test for cars could be improved, study concludes
A test currently under development for certifying levels of vehicle emissions may not adequately represent real world driving conditions, a new study suggests. The authors measured emissions during the new Worldwide Light-Duty Test Cycle (WLTC) compared with those in existing driving cycles and highlighted areas where the test could be potentially improved. In the EU, tailpipe emissions from new ...

Climate Models Project Increase in U.S. Wildfire Risk
Scientists using NASA satellite data and climate models have projected drier conditions likely will cause increased fire activity across the United States in coming decades. Other findings about U.S. wildfires, including their amount of carbon emissions and how the length and strength of fire seasons are expected to change under future climate conditions, were also presented Tuesday at the ...

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 ...

Better estimates of worldwide mercury pollution
Original story at MIT News Once mercury is emitted into the atmosphere from the smokestacks of power plants, the pollutant has a complicated trajectory; even after it settles onto land and sinks into oceans, mercury can be re-emitted back into the atmosphere repeatedly. This so-called “grasshopper effect” keeps the highly toxic substance circulating as “legacy emissions” ...

Geotech’s first GA5000 landfill gas analyser takes 100,000 readings for SUEZ environnement
Geotech's first GA5000 analyser, manufactured three years ago, was recently spotted in the company's calibration rig. This portable landfill gas monitor was the first production unit of the newly launched GA5000 gas analyser range and has prompted Geotech to look into the analyser's life since then. The analyser was on its sixth service since manufacture, under Geotech's Service Plus scheme, ...
