Pollution

• Introduction of contaminants into the natural environment that cause adverse change.

• Pollution can take the form of chemical substances or energy, such as noise, heat or light.

• Pollutants is the components of pollution (i.e the make up)

Merriam-Webster Online Dictionary

Classification of Pollution

• Sources– Point Source – Non Point

• Forms• Causes• Pollutants• Hazardous effects

Major types of Pollution

• Air Pollution• Water Pollution• Environmental or Soil Pollution

Other types of Pollution

• Noise Pollution• Radioactive Pollution

Air Pollution• Machinery emits harmful chemicals as wastes.• Chemicals contains mostly poisonous and toxic gases• E.g of air pollutants includes benzene, methane CO

etc.• The chemical company permits these toxins to be

released without treating them.• The untreated, toxic chemicals are released directly

into the air and causes different types of effect spanning from the environment to the human health.

Spengler et all, 1983

Air Pollution in different forms

Water Pollution

• Presence of solid, liquid, or gaseous contaminats in water.

• Chemicals are released into the stream water without being treated.

• Also cause different types of health effects in both plant and animals

Environmental or Soil Pollution

• Polluting the Environment in diffrent forms• A good example is a mechanical motor garage

that work on cars accumutaling waste oil on the soil

• Pollutants are absorbed by plants• Toxic absorbed chemicals enters the nutrient

cycle, food web, or food chain.

Effects of Pollution

1. Environmental Degradation 2. Health Effects3. Effects on Global Warming4. Ozone Layer Depletion

Environmental Degradation

– Increase in CO, CO2 causes smog– Smog reduces the sunligh that reaches plants– Plants cannot process photosynthesis with

reduced Sunlight– Smog reduces transperancy in water– Oxides of Sulfur causes Acid rain

– Increase in CO, CO2reduces O2 availability

Human Effects of Pollution

Global Warming Effect of Pollution

• Increase of Earth's average surface temperature.

• Increases in gaseous pollutants especially CH4, Oxides of Nitrogen, CO and CO2 Increases global warming

Effect of Global Warming

• These images show the five-year average variation of global surface temperatures in 1884, 1927, 1969 and 2012. Dark blue indicates areas cooler than average. Dark red indicates areas warmer than average. Source: NASA/Goddard Scientific Visualization Studio

Ozone Layer Depletion Effect

• Ozone Layer is the thin shield high up in the sky that stops ultra violet rays from reaching the earth.

• Pollutants such as CFCs, CH4, CO CO2 were released in to the atmosphere which contributed to the depletion of ozone layer.

Pollution Prevention and Its Social Values

• It means the control of emissions and effluents into air, water or soil.

• Without pollution control, the waste products will degrade the enviroment for the public use.

• Pollution prevention are more desirable than pollution control in the society

Socials Values in Preventing Pollution

• Social Value: is created when resources, inputs, processes or policies are combined to generate improvements in the lives of individuals or society as a whole.

• The following slides will showcase examples of social values in Preventing pollution

Our Recommendations

• Educational programes and awereness advert on T.V, bilborad etc should increase.

• More researches equating the amout of waste to substacial values or materials so the lay man can understand the great demage he his causing by polluting the environment

• Usage of biodegradable products• Laws and legistalations against pollution
