example
The majority of bivalves feed by removing 'particulate' organic matter from water that is circulated through the gills by cilliary activity.
The results of two recent studies have demonstrated an association between postneonatal mortality and 'particulate' air pollution.
'particulate' matter
Healthy human volunteers experienced artery vasoconstriction when they breathed fine 'particulate' air pollution and ozone.
But there's another major contributor to small 'particulate' pollution that most of us don't know about: those increased levels of wood smoke in winter.
With less 'particulate' matter, carbon monoxide and sulphur dioxide emissions are also less.
Perhaps these findings suggest a causative link between the rising levels of 'particulate' air pollution from motor vehicles and the increase in the prevalence of atopy.
This 'particulate' pollution has been implicated in rising rates of asthma, now the most common chronic childhood disease in the United States.
Moreover, the use of fossil fuels puts our own health at risk through the chemical and 'particulate' pollution it creates.
The sulfur dioxide and other 'particulate' emissions coupled with gasoline are not found in ethanol, making the alcohol fuel a much cleaner burning alternative.
Bio-diesel fuelled engines, like their regular fuel counterparts, still emit carbon monoxide, unburned hydrocarbons, carbon dioxide and 'particulate' matter.
City traffic is a significant source of pollutants such as sulphur dioxide, 'particulate' matter, benzene, and carbon monoxide.
We also identified sites with higher levels of 'particulate' pollution than did previous studies, the purpose of which was to maximize the effect of the exposure.
During the early 1980s the primary sources of Arctic 'particulate' pollution are believed to have been from Russia and Europe.
Zinc oxide is a common, biologically active constituent of 'particulate' air pollution as well as a workplace toxin.
According to the Natural Resources Defense Council, 'particulate' air pollution kills more than 5,000 people a year in that state.
This ratio is driven by the settling rate and the nature of organic matter and 'particulate' iron, as well as the supply of oxygen, nitrate, and sulfate to the sediment.
We cannot attribute the observed adverse effects to any single pollutant, although 'particulate' pollution may be a strong candidate.
A pond has far more organic 'particulate' matter (small separate particles) than a chemically maintained swimming pool.
Other precautions include staying inside on high 'particulate' pollution days and making sure your child is not exposed to too much diesel pollution on school buses.
Despite these differences, it appears that asthma disease is exacerbated by 'particulate' pollution in Anchorage, as it is in other cities in which it has been studied.
The number of ozone-alert days is used as an indicator of air quality, as are the amounts of pollutants, including 'particulates' , carbon monoxide, sulfur dioxide, lead, and volatile organic chemicals.
Ship engines release significant amounts of nitrogen oxides, diesel 'particulates' and sulfur into the atmosphere.
Biodiesel reduces emissions of unburned hydrocarbons, carbon monoxide, sulfates, polycyclic aromatic hydrocarbons, nitrated polycyclic aromatic hydrocarbons and 'particulates' .
The rail companies will use the grant to retrofit 10 switcher locomotives in the valley to reduce emissions of nitrogen oxides, sulfur dioxide and diesel 'particulates' .
Outdoor burning releases high concentrations of carcinogens, 'particulates' , carbon monoxide and many other toxins.
Climate change is caused by industries fouling the air with 'particulates' , methane, carbon dioxide, and other gases.
According to EPA's ‘Green Vehicle Guide,’ diesel engines emit 16 times more 'particulates' than gasoline engines, although standards set for 2007 should lessen the problem.
The disadvantage is higher levels of NOX [nitrous oxides] and 'particulates' .
The 'particulates' , or soot, in diesel exhaust cause a host of health problems, from asthma to lung disease to premature death, according to the Environmental Protection Agency.
