Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
Relating to or in the form of minute separate particles.‘particulate pollution’
- ‘The results of two recent studies have demonstrated an association between postneonatal mortality and particulate air pollution.’
- ‘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.’
- ‘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.’
- ‘The majority of bivalves feed by removing particulate organic matter from water that is circulated through the gills by cilliary activity.’
- ‘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.’
- ‘Moreover, the use of fossil fuels puts our own health at risk through the chemical and particulate pollution it creates.’
- ‘We cannot attribute the observed adverse effects to any single pollutant, although particulate pollution may be a strong candidate.’
- ‘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.’
- ‘This particulate pollution has been implicated in rising rates of asthma, now the most common chronic childhood disease in the United States.’
- ‘Bio-diesel fuelled engines, like their regular fuel counterparts, still emit carbon monoxide, unburned hydrocarbons, carbon dioxide and particulate matter.’
- ‘Healthy human volunteers experienced artery vasoconstriction when they breathed fine particulate air pollution and ozone.’
- ‘According to the Natural Resources Defense Council, particulate air pollution kills more than 5,000 people a year in that state.’
- ‘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.’
- ‘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.’
- ‘With less particulate matter, carbon monoxide and sulphur dioxide emissions are also less.’
- ‘During the early 1980s the primary sources of Arctic particulate pollution are believed to have been from Russia and Europe.’
- ‘A pond has far more organic particulate matter (small separate particles) than a chemically maintained swimming pool.’
- ‘The sulfur dioxide and other particulate emissions coupled with gasoline are not found in ethanol, making the alcohol fuel a much cleaner burning alternative.’
- ‘Zinc oxide is a common, biologically active constituent of particulate air pollution as well as a workplace toxin.’
- ‘City traffic is a significant source of pollutants such as sulphur dioxide, particulate matter, benzene, and carbon monoxide.’
Matter in particulate form.
- ‘These devices collect chemicals and particulates from the air close to the body to determine what is in the air the person is inhaling.’
- ‘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.’
- ‘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.’
- ‘By that date, diesel-engine manufacturers were to restrict emissions of nitrous oxides and particulates to tough new limits.’
- ‘Most of the particulates came from wallboard, ceiling tiles, window glass, concrete, and the fireproofing material covering the steel beams.’
- ‘The disadvantage is higher levels of NOX [nitrous oxides] and particulates.’
- ‘Biodiesel reduces emissions of unburned hydrocarbons, carbon monoxide, sulfates, polycyclic aromatic hydrocarbons, nitrated polycyclic aromatic hydrocarbons and particulates.’
- ‘If it's an outdoor pool, the wind brings all sorts of particulates (solid things, like dust and leaves) that land in the water and stay there.’
- ‘Aluminum is derived in a process that produces air pollutants (e.g., particulates and gaseous fluorides, sulfur dioxide, particulate matter).’
- ‘The results were consistent with the soluble metal concentrations of the particulates, rather than the total metal concentrations, with non-water soluble or biologically available forms of metal having no effect.’
- ‘Ship engines release significant amounts of nitrogen oxides, diesel particulates and sulfur into the atmosphere.’
- ‘‘Besides particulates, wood smoke contains nitrogen dioxide, carbon monoxide and many organic compounds such as aldehydes,’ says Rosenberg.’
- ‘Air movement and thermal currents transport dust and microbial particulates; particles that become airborne then can settle on open wounds.’
- ‘Climate change is caused by industries fouling the air with particulates, methane, carbon dioxide, and other gases.’
- ‘For example, high levels of carbon monoxide, nitrogen dioxide, and particulates (microscopic air panicles) are linked to increased cases of congestive heart failure and heart disease deaths.’
- ‘Outdoor burning releases high concentrations of carcinogens, particulates, carbon monoxide and many other toxins.’
- ‘The resulting harmful gases include carbon monoxide, nitrogen dioxide, sulfur dioxide, particulates and excess water vapor.’
- ‘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.’
- ‘We found no correlations between the levels of particulates, carbon dioxide, and other chemicals, and occupant complaints.’
- ‘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.’
Late 19th century: from Latin particula particle + -ate.
