Overall, when simulation models are used for studies related to solute transport, polluted soil remediation, irrigation management and others, erroneous measurement of the SWRC for fine textured soils, may lead to erroneous computation of the soil water balance.
Higher mass concentrations have been found during summer when convection occasionally transports polluted air masses to JFJ and SNB.
We are addressing the major causes of greenhouse gas emissions: polluting transport, old and/or poorly isolated buildings and energy supply.
Imagining a world where the freeways aren't clogged with huge, noisy, loud, polluting transport trucks presents a tempting vision, especially for frequent commuters.
When every form of transportation is inherently polluting (and travel requires transport) what is really "green" other than pitching a tent in your back yard?
To turn the pollution clock back, Beijing has brought down the number of cars that can be sold in a year, denied any significant price advantage to diesel cars, introduced Euro V standards, invested in public transport and reined in polluting industries.
Agriculture and international shipping "pollute more than the air transport industry," he said, adding that the industry had reduced aircraft noise 70 percent in the past 20 years.
"Suppose we get half a million cars off the streets, we would be sending 800,000 people to the public transport system, which pollutes between four and five times more than private cars".
The first, on land, concerns a proposed European effort to discourage more-than-usually polluting sources of transport fuel, known as the Fuel Quality Directive.
The reason is aviation's massive contribution to global warming: it appears to be at least as polluting as road transport in terms of greenhouse gas emissions and depletion of the ozone layer.
