Carbon Dioxide uses a lot of space in the air instead of oxygen creating an asphyxiating feeling.  There are many symptoms caused by CO2 such as dizziness and headache. Thi colorless gas usually comes from industrial processes that produce hydrogen and ammonia from natural gas, coal, or large-volume fermentation operations are some of the largest commercial producers of carbon dioxide. High concentration of carbon dioxide can toxic.

      Carbon Dioxide (CO₂ )

      CO₂ is a greenhouse gas that is natural and harmless in small quantities but as levels rise it can be dangerous to your health. Most commonly produced by the air we exhale, CO₂ levels concentrate indoors with less ventilation.

      Exposure to high carbon dioxide levels can cause: suffocation by displacement of air, incapacitation and unconsciousness, headaches, vertigo and double vision, inability to concentrate, tinnitus, seizures. 

      Fine particles (PM2.5)

      PM2.5 are 2.5 micrometers in diameter or smaller, and can only be seen with an electron microscope. Fine particles are produced from all types of combustion, including motor vehicles, power plants, residential wood burning, forest fires, agricultural burning, and some industrial processes.

      Exposure to PM2.5 has multiple short-term and long-term health impacts. The short term includes irritation in the eyes, nose, and throat, coughing, sneezing, and shortness of breath. Prolonged exposure to PM2.5 can cause permanent respiratory problems such as asthma, chronic bronchitis, and heart disease.

      Coarse dust particles (PM10)

      PM10 is 2.5 to 10 micrometers in diameter. Sources include crushing or grinding operations and dust stirred up by vehicles on roads. These tiny particles which are about 30 times smaller than the width of the hair on your head are small enough to get inhaled past our defensive nose hairs and into our lungs.

      Formaldehyde (HCHO)

      HCHO is a colorless, poisonous, highly water-soluble gas with an obnoxious odor. Used in the manufacture of disinfectants, preservatives, and hundreds of industrial and consumer products such as adhesives, carpeting, decorative paneling, foam insulation, drapery, fiber and particle boards, and permanent press fabrics.
