The fine particles are mostly made from gases. There are four major origins for that gases which are responsible for these particles: rock (vaporized during combustion or casting), carbon from combustion, organic carbon, sulfates and nitrates. Take sulphur dioxide. It is created during engine combustion, but when it climbs into the atmosphere and mixes with rain it will become sulphuric acid. We all probably know very well what that will do- since it is highly corrosive and dangerous in concentration. The manual wheelchair has been around use for many years and has gone through many changes. The constant feature has been that this chair is self propelled by pushing for the hand edges that surround the wheels. The owner actually pushes the wheels around and around to get in one location to another. In addition to that, the footrests with a manual wheelchair is easy to remove and the user can walk the chair forward together with his feet. Particulate air pollution is really a combination of solid and liquid particles which are suspended up which you breathe. It is best to classify air particles through the aerodynamic properties since these properties determine removing them through the air, and where they deposit in your the respiratory system.
