  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. 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]

    Long-term exposure to PM 2.5 (fine particulates) increases the overall risk of non-accidental mortality by 6% per 10 μg/m 3 increase. Exposure to PM 2.5 is also associated with an increased risk of mortality from lung cancer (range: 15–21% per 10 μg/m 3 increase) and total cardiovascular mortality (range: 12–14% per 10 μg/m 3 increase ...

  5. Venturi scrubber - Wikipedia

    en.wikipedia.org/wiki/Venturi_scrubber

    Particles and droplets impact on the pool of liquid, reducing wear on the scrubber shell. A common technique to help reduce abrasion is to use a precleaner (i.e., quench sprays or cyclone) to remove the larger and more damaging particles. This also has the added benefit reducing the particle load carried by the liquid.

  6. Nonpoint source pollution - Wikipedia

    en.wikipedia.org/wiki/Nonpoint_source_pollution

    These toxins are a particular problem in systems used for drinking water because some toxins can cause human illness and removal of the toxins is difficult and expensive. Bacterial decomposition of algal blooms consumes dissolved oxygen in the water, generating hypoxia with detrimental consequences for fish and aquatic invertebrates. [11]

  7. Particle counter - Wikipedia

    en.wikipedia.org/wiki/Particle_counter

    A particle counter is used for monitoring and diagnosing particle contamination within specific clean media, including air, water and chemicals. Particle counters are used in a variety of applications in support of clean manufacturing practices, industries include: electronic components and assemblies, pharmaceutical drug products and medical devices, and industrial technologies such as oil ...
