Pollution

Pollution has become a preoccupation with scientists' minds. They are calling for a halt to this environmental pollution as a result of industrial renaissance and technological progress in this age.

Environmental pollution is no less dangerous than wars, conflicts and chronic diseases.

Recently, studies and legal thought have begun to deal with environmental issues, and many studies, conferences and agreements dealing with this issue have appeared to reduce pollution.

Sources of water pollution

Some ways to protect the land from pollution

1. Spread environmental awareness among citizens about the importance of the environment and its preservation, and the bad consequences of not maintaining it.

2. The enactment of laws and legislation that provide for the preservation of the environment and the punishment of any procrastinators.

3. Minimize logging because it works to soften the atmosphere for its oxygen production in photosynthesis.

4. Properly disposed of waste such as sanitary landfill or recycling, and dumped it in designated areas.

5. Reduce the excessive use of chemicals and pesticides in a manner that causes disease and poses a threat to living organisms in the environment.

6. The establishment of a forestation campaigns for vacant lands, in order to reduce soil erosion in order to preserve the environment in these areas.

7. Rationalization of the use of water and not wasteful, as well as not dumping pollutants in water sources.

8. Proper disposal of waste water and non-dumping in river or sea waters which constitutes a threat to marine life.

9. Reduce the noise of cars and factories, which are one of the largest environmental pollutants.

10. Do not kill wild animals or hunt it in a way that causes an imbalance in the ecosystem.

AIR POLLUTION • The condition in which air is contaminated by foreign substances, or the substances them selves. • Air pollution consists of gaseous, liquid, or solid substances that, when present in sufficient concentration, for a sufficient time, and under certain conditions, tend to interfere with human comfort, health , and cause environmental damage. by hiba ayadi tunisia

There are four main types of air pollution sources:

mobile sources – such as cars, buses, planes, trucks, and trains

stationary sources – such as power plants, oil refineries, industrial facilities, and factories

area sources – such as agricultural areas, cities, and wood burning fireplaces

natural sources – such as wind-blown dust, wildfires, and volcanoes

1.1 Introduction

In the current Anthropocene, environmental pollution is a global problem that is inextricably linked with rapid industrialization and urbanization. Pollution hampers the environment sustainability and ecosystem services. In this chapter, we will briefly introduce environmental pollution (now popularly called pollution science) before the introduction of the theme topic.

1.1.1 Pollution Science

Environmental pollution is the unfavorable alteration of our surroundings, wholly or largely as a byproduct of man's actions, through direct or indirect effects of the changes in the energy pattern, radiation levels, and chemical and physical constitution and abundance of organisms. Environmental pollution is a global problem and is common to both developed as well as developing countries, which attracts the attention of human beings for its severe long-term consequences. The decline in environmental quality as a consequence of pollution is evidenced by loss of vegetation, biological diversity, excessive amounts of harmful chemicals in the ambient atmosphere and in food grains, and growing risks of environmental accidents and threats to life support systems. Pollution is viewed from different angles by different people but is commonly agreed to be the outcome of urban-industrial and technological revolution and rapacious and speedy exploitation of natural resources, increased rate of exchange of matter and energy, and ever-increasing industrial wastes, urban effluents, and consumer goods. Holdgate (1979) defined environmental pollution as the introduction by man, into the environment, of substances or energy liable to cause interference with legitimate uses of environment. Singh (1991) has defined pollution in a very simple manner, i.e., "Disequilibrium condition from equilibrium condition in any system." This definition may be applied to all types of pollution ranging from physical to economic, political, social, and religious. Over the past couple of decades, various sources of pollution were identified that altered the composition of water, air, and soil of the environment. The substances that cause pollution are known as pollutants. A pollutant can be any chemical (toxic metal, radionuclides, organophosphorus compounds, gases) or geochemical substance (dust, sediment), biological organism or product, or physical substance (heat, radiation, sound wave) that is released intentionally or inadvertently by man into the environment with actual or potential adverse, harmful, unpleasant, or inconvenient effects. Such undesirable effects may be direct (affecting man) or indirect, being mediated via resource organisms or climate change. Depending on the nature of pollutants and also subsequent pollution of environmental components, the pollution may be categorized as follows:

Among these types of pollution, air pollution is the main type threatening the environment, humans, plants, animals, and all living organisms.

Motor vehicles cause most of our air pollution. They release more than 60 per cent of the dangerous gases into the air. In large cities cars are responsible for about 80 per cent of the air pollution.
