  2. Particulate pollution - Wikipedia

    en.wikipedia.org/wiki/Particulate_pollution

    PM 10, also known as coarse particulate matter, consists of particles 10 micrometers (μm) and smaller, while PM 2.5, also called fine particulate matter, consists of particles 2.5 μm and smaller. [29] Particles 2.5 μm or smaller in size are especially notable as they can be inhaled into the lower respiratory system, and with enough exposure ...

  3. Microparticle - Wikipedia

    en.wikipedia.org/wiki/Microparticle

    Microparticles are particles between 0.1 and 100 μm in size. Commercially available microparticles are available in a wide variety of materials, including ceramics, glass, polymers, and metals. [2] Microparticles encountered in daily life include pollen, sand, dust, flour, and powdered sugar.

  4. Particulates - Wikipedia

    en.wikipedia.org/wiki/Particulates

    Particulates or atmospheric particulate matter (see below for other names) are microscopic particles of solid or liquid matter suspended in the air.The term aerosol refers to the particulate/air mixture, as opposed to the particulate matter alone, [1] though it is sometimes defined as a subset of aerosol terminology. [2]

  5. Aerosol - Wikipedia

    en.wikipedia.org/wiki/Aerosol

    An aerosol is a suspension of fine solid particles or liquid droplets in air or another gas. [1] Aerosols can be generated from natural or human causes. The term aerosol commonly refers to the mixture of particulates in air, and not to the particulate matter alone. [2] Examples of natural aerosols are fog, mist or dust.

  6. Dust - Wikipedia

    en.wikipedia.org/wiki/Dust

    Dust in homes is composed of about 20–50% dead skin cells. [2] The rest, and in offices and other built environments, is composed of small amounts of plant pollen, human hairs, animal fur, textile fibers, paper fibers, minerals from outdoor soil, burnt meteorite particles, and many other materials which may be found in the local environment. [3]

  7. Infiltration (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Infiltration_(hydrology)

    Clay particles in the soil may swell as they become wet and thereby reduce the size of the pores. In areas where the ground is not protected by a layer of forest litter, raindrops can detach soil particles from the surface and wash fine particles into surface pores where they can impede the infiltration process.

    en.wikipedia.org/wiki/Marine_sediment

    Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.These particles either have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea, or they are biogenic deposits from marine organisms or from ...
