Slide Content
Nitrogen dioxide (N in air is oxidized); No sum of NO, NO , other oxides of N Brownish gas irritates the respiratory system originates from combustion Burning fuels including petrol, diesel, and coal Ground level O3 (primary constituent of smog) Reaction of VOC + nox in presence of heat +sun light Vehicles and industries are the major source Carbon monoxide Reduces bloods ability to carry O Produced by the incomplete burning of carbon-based fuels & natural and synthetic products such as cigarettes Carbon dioxide Principle greenhouse gas. Emitted as a result of human activities such as the burning of coal, oil, and natural gases Sulphur dioxide Precursor to acid rain along with Nox Formed when fuel (coal, oil) containing S is burned and metal smelting Chorofluoro carbon (CFC) Ozone depletion Released from air- conditioning systems and refrigeration. Lead Cause learning disabilities in children , toxic to liver, kidney, blood forming organs Present in petrol, diesel, lead batteries, paints, hair dye products, etc Particulate matter (PM 10 & 2.5)
