Definition of particulate in English:



  • Relating to or in the form of minute separate particles.

    • ‘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.’
    • ‘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.’
    • ‘City traffic is a significant source of pollutants such as sulphur dioxide, particulate matter, benzene, and carbon monoxide.’


  • Matter in the form of minute separate particles.

    ‘sooty particulates from diesel exhausts’
    • ‘As a smoker, I fully agree that non-smokers are entitled to a smoke-free environment, but in the bus stations diesel buses are entering and leaving, emitting particulates and exhaust gases which are all-pervading.’
    • ‘Putting a lacquer on the outside of a piece of timber and having zinc oxide nano particulates embedded in that lacquer makes that lacquer protective against ultra violet radiation.’
    • ‘A major stumbling block in the development of these technologies to complement diesel engines has been the high levels of sulphur and of sooty particulates which rapidly foul emission reduction systems.’
    • ‘Erosion consequent on agriculture, deforestation, construction, or mining operations can deposit particulates like soil into water bodies.’
    • ‘The M.E.N. research, published on Friday, shows the quantity of particulates - solid dust and fume which can be inhaled into the lungs - has risen by 10 per cent at Manchester's Piccadilly and a site in Bolton since 1998.’
    • ‘Admittedly, while petrol engines emit more carbon dioxide, diesels emit more particulates, which cause pollution at local level.’
    • ‘Carbon monoxide and various hydrocarbons and particulates are also in the fumes’
    • ‘‘Nitrogen dioxide and particulates do exceed the criteria at some urban roadsides,’ said a spokeswoman.’
    • ‘Indeed, it reduces harmful emissions by 75 per cent with less carbon dioxide than petrol and fewer particulates and nitrogen oxides than diesel.’
    • ‘But they could not take the carbon monoxide and diesel particulates and wilted.’
    • ‘When the solar power fades, a diesel generator would kick in, but a more efficient engine would be installed that produced one-third of the carbon particulates that direct-drive diesel engines emitted.’
