Ambient air is the atmospheric air that surround

ﺇﺩﺍﺭﺓ ﺟﻮﺩﺓ ﺍﻟﻬﻮﺍﺀ Ambient air is the atmospheric air that surround us , Ambient air is typically • 78% nitrogen • 21% oxygen • 3% carbon dioxide • 1% is made up of argon and other gases. The process of air pollution occurs if there is a change in the composition of ambient air caused by air pollutants such as: smoke, dust, gases, vapors, spray and substances that smell, affect public health or cause damage to plants and properties of buildings.

ﺇﺩﺍﺭﺓ ﺟﻮﺩﺓ ﺍﻟﻬﻮﺍﺀ How air pollution affects humans The increase in the level of air pollutants leads to low air quality and can cause various health problems related to the respiratory system and heart. Some air pollutants such as benzene are also classified as carcinogens. Air pollution is highly harmful to the environment. Sources of air pollution: • • • Transportation Power generation Industries Oil Refineries Household resources and others

ﺇﺩﺍﺭﺓ ﺟﻮﺩﺓ ﺍﻟﻬﻮﺍﺀ Air quality monitoring Pollutants monitored for air quality measurements are: • Ozone • Suspended particles with a diameter less than 2. 5 microns and 10 microns • sulfur dioxide • Nitrogen Oxides • Carbon Monoxide In addition to measuring volatile organic compounds and meteorological data such as wind speed, temperature, humidity.

ﺇﺩﺍﺭﺓ ﺟﻮﺩﺓ ﺍﻟﻬﻮﺍﺀ Why do we care about dust storms? Dust storms can cause many health problems through the penetration of particles to the lungs and thus cause serious damage to human health such as breathing problems, cough, runny nose and chronic problems in breathing and lung. Causes of dust storms: • Climate conditions • Conditions of the natural environment • Human activity • High winds

ﺇﺩﺍﺭﺓ ﺟﻮﺩﺓ ﺍﻟﻬﻮﺍﺀ Some individual initiatives to help reduce air pollution: • As the transport sector is the main cause of air pollution, use environmentally friendly transport methods such as walking, cycling and public transport. • Maintain the vehicle periodically. • Check tire pressure per month. • Avoid filling the tank with fuel to the upper limit.
