    • ‘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.’
