Looking for an explanation of what air pollution is?
The disgraceful lack of control and study of the Alberta tar sands exploitation is leading to people's health problems. As the US considers its imports from Canada, it would be wise to consider just how neglectful the Canadians have been to their residents, air quality, water purity and forests.
Air pollution is rarely linked to water pollution, but the strong links will soon be obvious, just as the surface air movement is influenced by the ocean currents and the temperatures of both. While scientific models can tell us what is going to happen as the earth warms, climate change will also be influenced by small so far neglected fluctuations in chemistry such as these pH changes in our oceans, affecting billions of creatures, and of course, us.
Ecologists call for remaining biodiversity protection. 'Water purity, food production and air quality' are often taken for granted but do not simply 'come for free.'
Mountain pine beetles not only kill trees, they increase VOC levels in forested areas, a new study shows.
Even a short fall in air pollution can improve heart health, a study undertaken during the Beijing Olympics has discovered.
New research warns that the economic costs of asthma caused by traffic pollution are higher than previously thought.
Aerosols in the atmosphere can create severe storms, rain and snow in some areas and increase drought in others, according to leading scientists.
While air pollution is endangering tens of thousands in UK cities, the Government is seeking to reduce standards, so it can avoid European Union fines, it is claimed.
Air pollution exposure has been linked to a 30-percent increase in the risk of premature low-weight births among women living in Los Angeles, California. Air quality information was derived from three separate sources, and included data regarding concentrations of carbon monoxide, nitrogen dioxide, ozone, and fine particulate matter.
It may seem like common-sense to think that an individual living in the city is more likely to suffer from the effects of air pollution than someone in the country. However, you may want or need to consider a face mask if cycling in the city as a study has found increased black carbon intake for city cyclists.
This week the cost of development coming home to roost, literally, with the sky falling down, smoggiest levels for five years in the US and northern birds. One of several issues covered in our weekly roundup of environmental news up to 23rd September 2011.
A proposed ethanol-production facility in Mozambique will reduce deforestation, improve local farmer's sustainability, and help reduce air pollution. The plan calls for construction of an integrated food-energy business that will replace charcoal-burning fireplaces with ethanol-burning stoves.
In order to keep oil away from the shoreline of the Gulf of Mexico large amounts of the oil spilled by the Deepwater Horizon well in 2010 were burned, now scientists have measured the impact that decision had on air quality.
President Obama's U-turn over pressing for cleaner, smog-free air only makes sense in the hothouse of presidential re-election politics. In the real world, jobs, health and lives are at stake - and a faith in the American system of being able to deliver on its promises.
The Eyjafjallajokull volcano in Iceland came to global notice in April 2010 when its eruption and the resulting plume wreaked havoc on European air transportation. Researchers in Germany and Austria published a study on the consequences of the Eyjafjallajokull eruption on air quality.
New project launches to help improve scientists ability to track air pollutants via satellite. Low flying planes will be seen across Maryland in a programme called DISCOVER-AQ which is designed to improve the ability of satellites to measure the ground level air quality on earth from space.
Warm nighttime temperatures change wind patterns, trapping pollutants in cities. Amongst U.S. cities, Houston has some of the highest levels of pollutants like ozone at the ground level. In Houston, urban development inhibits winds from sweeping pollutants out to the ocean at night.
Choosing detoxifying houseplants can improve indoor air quality by reducing pollutants and airborne bacteria.
New transportation options can help to cut back on greenhouse gasses and reduce air pollution in the environment.
A customized tool for picking up on very low levels of noxious burning byproducts has enabled NOAA scientists to sniff out isocyanic acid - a chemical linked to known health problems - in LA smog and wildfire smoke. This compound is though likely to be at worryingly high levels in cigarette smoke, as well as homes using poorly-drafted wood fires, and may increase as the planet hots up, says the paper in the Proceedings of the National Academy of Sciences.
Pollution levels in China's rural areas to be cut by 2015. China's rapid industrial growth over the last generation has come at a cost. Air pollution causes an estimated 400,000 deaths a year along with 75 million asthma attacks. This year the Chinese government announced an ambitious programme to cut the country's pollution, embarking on a programme beginning in 2011 until 2015.
Feeling a bit short of breath? You can blame pollution. A research group based at the University of Rochester Medical Centre in New York has been measuring our response to miniscule particles found in our atmosphere. The pollutant particles, which we breathe in as part of our everyday life, have long been associated with and thought to exacerbate several cardiovascular and respiratory conditions.
We all know chemicals in the air can harm us but new research centers in American universities are getting government cash to examine how pollutants interact. Scientists in American universities will receive money from the US Environmental Agency to investigate how pollution in the air affects us by examining how pollutants act together when mixed. Each of four new centers will receive $8million dollars over the next five years to examine how possibly harmful chemicals interact with each other.
As China heads towards revealing a major plan to reduce air pollution, residents of Beijing are suffering from some of the worst air conditions to date. Beijing air quality levels were recorded by the U.S. Embassy staff based in the city as exceeding the standard levels. The maximum level of the air quality charts is 500 API (Air Pollution Index), but in Beijing the recordings soared to a massive 595 API.
Excess nitrogen is responsible for marine dead-zones, global warming and smog, and now two scientists want us all to measure our nitrogen footprints. Scientists at the University of Virginia have produced a 'nitrogen footprint' calculator to raise awareness of an environmental problem little known outside specialist circles.
New 'contraption' aims to tackle London's air quality by 'gluing pollution to the streets'. The latest bid to tackle London's increasingly poor air quality will see a special solution sprayed onto the capital's roads.
