What are the common air cleaning devices?

Particle Removal Two types of air cleaning devices can remove particles from the air — mechanical air filters and electronic air cleaners. Mechanical air filters remove particles by capturing them on filter materials. High efficiency particulate air (HEPA) filters are in this category.

What is the name of the instrument used for monitoring ambient air quality?

The air quality meter PCE-RCM 15 is specially designed to monitor the quality of indoor air. Among other things, the air quality meter measures the parameters for PM1, PM2. 5, PM10, TVOC, formaldehyde, humidity and temperature.

What is ambient air quality monitoring system?

Ambient air monitoring is the systematic, long-term assessment of pollutant levels by measuring the quantity and types of certain pollutants in the surrounding, outdoor air.

Who is most sensitive to poor air quality?

What Groups are Most “Sensitive” to Air Pollution?

  • Anyone who suffers from heart disease, congestive failure or coronary artery disease.
  • Expectant women.
  • Individuals that already suffer from lung conditions such as chronic obstructive pulmonary disease, emphysema, and asthma.
  • People who work outdoors.

What are the five major components to be taken as criteria for air pollution and why?

Criteria Air PollutantsThese pollutants are particulate matter, photochemical oxidants (including ozone), carbon monoxide, sulfur oxides, nitrogen oxides and lead.

What is ambient pollution?

Ambient air pollution is a broader term used to describe air pollution in outdoor environments. Poor ambient air quality occurs when pollutants reach high enough concentrations to affect human health and/or the environment.

What is normal ambient air?

Ambient air is typically 78% nitrogen and 21% oxygen. The extra 1% is made up of a combination of carbon, helium, methane, argon and hydrogen. The closer the air is to sea level, the higher the percentage of oxygen.

What is the largest source of air pollution in the world today?

Human activities that are major sources of outdoor air pollution, include: Fuel combustion from motor vehicles (e.g. cars and heavy duty vehicles) Heat and power generation (e.g. oil and coal power plants and boilers) Industrial facilities (e.g. manufacturing factories, mines, and oil refineries)
