What is AIR POLLUTION? AIR POLLUTION affects many aspect such as; Health Environment Destroys living organisms Economic status
short-term or long-term adverse effect. Based on research; Around 3 billion people cook and heat their homes using open fires and leaky stoves burning biomass (wood, animal dung and crop waste) and coal. Nearly 2 million people die prematurely from illness attributable to indoor air pollution from household solid fuel use. Nearly 50% of pneumonia deaths among children under five are due to particulate matter inhaled from indoor air pollution. More than 1 million people a year die from chronic obstructive respiratory disease (COPD) that develops due to exposure to such indoor air pollution. Both women and men exposed to heavy indoor smoke are 2-3 times more likely to develop COPD.
Formation of VOC through evaporation and incomplete combustion. Biological generation of VOC. Formation of liquid aerosol droplets through shear and turbulence related processes, from cooking and household solvent based cleaners. Anthropomorphic generation of particulate aerosol. PRIMARY MECHANISM OF AIR POLLUTION
Biological formation of particulate aerosols through decomposition and spore formation. Particulate aerosol floral and weather based phenomenamation from geologic. SECONDARY MECHANISM OF AIR POLLUTION Condensation -- Liquid aerosol droplet formation due to condensation of gaseous phase components.
Adsorption -- Adsorption of gaseous phase and liquid aerosol components onto particulate surfaces, resulting in particulate aerosols with modified surfaces from adsorption of organic compounds and hydrous inorganic phases. Nucleation -- Liquid aerosol formation through precipitation onto micro particulate nucleation sites.
AIR POLLUTION IMPACTS TO ENVIRONMENT AND PEOPLE: PollutantSourceHealth Ozone (O3)Action of sunlight on NO 2, HC's Asthma ; Bronchitis ; Irritation to the eyes and mucous membranes ; Headaches ; Nose & throat irritation LeadTransportation Industry Reduced birth weight and lowered intelligence Carbon dioxideBurning of fossil fuels Combustion in motor vehicles Headaches Asphyxiation Impairment of performance on tasks requiring attention Aggravation of cardiovascular disease Enhances global warming Suspended particlesBurning of fossil fuels, untarred roads, mining dust and agriculture Damage to lung tissues causing respiratory disease
Sulphur dioxideBurning of fossil fuels (coal) Causes constriction of the airways in people with asthma, repeated exposure causes a condition similar to bronchitis. Increased risk of acute respiratory disease Causes acid rain Nitrogen dioxideBurning of fossil fuels especially motor vehicles Can irritate the lungs, aggravate the condition of people suffering from asthma or chronic bronchitis HydrocarbonsVehicles and inudstrial processes Can cause some defects in babies during pregnancy or cancer. Precursor to photochemical smog, which causes respiratory diseases Carbon monoxideVehicle emissionsRestricts oxygen uptake Causes drowsiness, headaches, death
MITIGATION OF AIR POLLUTION AIR POLLUTION CONTROL ACT OF 1995 was the first United States Clean Air Act enacted by Congress to address the national environment problem of air pollution on July 14, 1995.
CONCLUSION AND RECOMMENDATION Air Pollution is not a huge problem for every country if we are responsible for our own acts. Air pollution can trigger us into danger, especially our health and environment.
FIVE STEPS TO CLEAN UP: 1.Clean up coal-fired power plant 2. Strengthen ozone air standards voluntarily 3. Clean up oceangoing vessels 4. Improve the pollution-monitoring network 5. Enforce the law
