When many of us think of pollution, images of smoggy cities and litter-infested oceans come to mind.

The main air pollutants are represented by gases forms, particles in suspension, different ionizing radiation and noise.

You were introduced to wastes and pollutants in Study Session 1, where we discussed the interactions between humans and our environment. Pollution was defined as the introduction into the environment of substances liable to cause harm to humans and other living organisms. Many human activities pollute our environment, adversely affecting the water we drink, the air we breathe, and the soil in which we grow food.

TYPES , CAUSES , IMPACTS AND MANAGEMENT FOR THE HEALTH AND SOCIO-ECONOMIC WELL-BEING

Pollution , we probably hear of this term every other day at school, college, and offices. We also come across the term in newspapers, online journals, and media in general. So what is it and why is it deemed harmful? Pollution occurs when pollutants contaminate the natural surroundings; bringing about changes that affect our normal lifestyles adversely. Pollutants are the key elements or components of pollution which are generally waste materials of different forms.

Pollution touches all parts of the planet. It is affecting our health through the food we eat, the water we drink and the air we breathe. Approximately 19 million premature deaths are estimated to occur annually as a result of the way we use natural resources to support global production and consumption and which impact the environment. Approximately 19 million premature deaths are estimated to occur annually as a result of the way we use natural resources and impact the environment to support global production and consumption. How does pollution fit in that picture? Pollution can take many forms, ranging from organic compounds and other chemical substances to different types of energy.

Water pollution , the release of substances into subsurface groundwater or into lakes , streams, rivers , estuaries , and oceans to the point where the substances interfere with beneficial use of the water or with the natural functioning of ecosystems. In addition to the release of substances, such as chemicals or microorganisms, water pollution may also include the release of energy , in the form of radioactivity or heat , into bodies of water. Water pollution is the release of substances into bodies of water that makes water unsafe for human use and disrupts aquatic ecosystems. Water pollution can be caused by a plethora of different contaminants, including toxic waste , petroleum , and disease-causing microorganisms. Human activities that generate domestic sewage and toxic waste cause water pollution by contaminating water with disease-causing microorganisms and poisonous substances. Oil spills are another source of water pollution that have devastating impacts on surrounding ecosystems.

Land Pollution: Causes, Effects, and Prevention

Theory of Environmental Pollution is one among them. In this article, we have thoroughly discussed the types, causes and impacts of different pollutions affecting humankind. Kidney problems, irritation in eyes, nose and throat, asthma, hypertension and carcinogenic effects on lungs. The improvement of nutrients in water bodies causes eutrophication. Domestic waste discharge, agricultural waste, land drainage and industrial waste in a water body leads to a rapid increase in nutrients in a water body which initiates early ageing of water bodies.

pollution due to urbanization and other anthropogenic substances causes soil pollution. Industrial waste: lead, cadmium, mercury, alkalies, organic substances, and chemicals. Agricultural waste: fertilizers, pesticides, insecticides, and manures. Discarded materials and radioactive elements and plastic bags.


WATER POLLUTION

The planet keeps nudging us with increasingly extreme droughts, reminding us that water is life. It is an essential resource upon which all living beings depend and it is crucial to all social and economic development, as well as energy production and adaptation to climate change. Nevertheless, we are now facing a gigantic challenge. How do we stop contaminating our rivers, seas, oceans, canals, lakes and reservoirs?

One of our era's greatest scourges is air pollution, on account not only of its impact on climate change but also its impact on public and individual health due to increasing morbidity and mortality. There are many pollutants that are major factors in disease in humans. Among them, Particulate Matter PM , particles of variable but very small diameter, penetrate the respiratory system via inhalation, causing respiratory and cardiovascular diseases, reproductive and central nervous system dysfunctions, and cancer. Despite the fact that ozone in the stratosphere plays a protective role against ultraviolet irradiation, it is harmful when in high concentration at ground level, also affecting the respiratory and cardiovascular system. Furthermore, nitrogen oxide, sulfur dioxide, Volatile Organic Compounds VOCs , dioxins, and polycyclic aromatic hydrocarbons PAHs are all considered air pollutants that are harmful to humans.

So, in land pollution as well, solid or liquid waste materials get deposited on land and further degrade and deteriorate the quality and the productive capacity of land surface. However, in fact, soil pollution is just one of the causes of the land pollution. Like the other types, land pollution also arises as a global environmental problem, specifically associated with urbanization and industrialization, that should be dealt with globally concerted environmental policies.
