Study Session 7 Pollution: Types, Sources and Characteristics

Jump to navigation. British poet W. This widespread problem of water pollution is jeopardizing our health. Unsafe water kills more people each year than war and all other forms of violence combined. Without action, the challenges will only increase by , when global demand for freshwater is expected to be one-third greater than it is now. Sip a glass of cool, clear water as you read this, and you may think water pollution is a problem. But while most Americans have access to safe drinking water , potentially harmful contaminants—from arsenic to copper to lead—have been found in the tap water of every single state in the nation.

When many of us think of pollution, images of smoggy cities and litter-infested oceans come to mind. While littering and gasoline-fueled cars are a major contributor to pollution, there are many other influences that are important to be aware of. Essentially, pollution occurs when substances are introduced to the environment that have harmful effects, damaging the quality of land, water, and air. The cause is the accumulation of solid and liquid waste materials that contaminate groundwater and soil. These waste materials are often referred to as municipal solid waste MSW , which includes both hazardous and non-hazardous waste.

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. In this and the next study session we will look more closely at pollution. In this session you will learn about the different types and sources of pollution and the various human activities that can cause pollution. We will also describe the ways pollution can affect different sectors of the environment: water, air and soil. Study Session 8 describes some of the significant effects of pollution on the environment and on human health.

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.

Water Pollution: Everything You Need to Know

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.

Land Pollution: Causes, Effects, and Prevention

Pollution , also called environmental pollution , the addition of any substance solid , liquid , or gas or any form of energy such as heat , sound, or radioactivity to the environment at a rate faster than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form. The major kinds of pollution, usually classified by environment, are air pollution , water pollution , and land pollution. Modern society is also concerned about specific types of pollutants, such as noise pollution , light pollution , and plastic pollution. Pollution of all kinds can have negative effects on the environment and wildlife and often impacts human health and well-being. Pollution occurs when an amount of any substance or any form of energy is put into the environment at a rate faster than it can be dispersed or safely stored. The term pollution can refer to both artificial and natural materials that are created, consumed, and discarded in an unsustainable manner.

Jerry Spiegel and Lucien Y. Over the course of the twentieth century, growing recognition of the environmental and public health impacts associated with anthropogenic activities discussed in the chapter Environmental Health Hazards has prompted the development and application of methods and technologies to reduce the effects of pollution. In this context, governments have adopted regulatory and other policy measures discussed in the chapter Environmental Policy to minimize negative effects and ensure that environmental quality standards are achieved. The objective of this chapter is to provide an orientation to the methods that are applied to control and prevent environmental pollution. The basic principles followed for eliminating negative impacts on the quality of water, air or land will be introduced; the shifting emphasis from control to prevention will be considered; and the limitations of building solutions for individual environmental media will be examined. It is not enough, for example, to protect air by removing trace metals from a flue gas only to transfer these contaminants to land through improper solid waste management practices.
