Water pollution is the contamination of water bodies , usually as a result of human activities. Water bodies include for example lakes , rivers , oceans , aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment.

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. When waste is deposited onto an area of land, the permeability of the soil formations below the waste can increase or reduce the risk of land pollution.
The higher the permeability of the soil, the more likely that land pollution will occur. By utilizing the natural shale and clay in the land, the risk of land pollution has been significantly decreased.
Yet, while there are now significantly safer practices for disposing of waste, there are still many other factors contributing to and worsening the situation. While there are many causes of land pollution, here are a few of the main contributors:.
Littering, the improper disposal of waste products, is unfortunately common. Every cigarette butt tossed on the ground or food wrapper tossed out of a car window is a small contribution to a monumental issue. Not all litter, however, is intentional. A large volume of litter also comes from unsecured items that fall off the back of vehicles or out of trash receptacles. All litter, whether intentional or not, causes pollution by releasing chemicals and microparticles as it degrades.
Check out our blog post on littering to learn more about the effects of littering and how to reduce it in your community. While urbanization is not in itself littering, large quantities of people living, producing trash and littering in a dense area does inevitably lead to land pollution.
To accommodate this increased population, construction activities also occur, which result in large waste materials, such as metal, plastic, wood, and bricks. When these materials are not properly disposed of, it contributes to the land pollution of that area. Mining is the extraction of minerals and other geological materials from the ground, which are then used for a wide range of purposes, including but not limited to, producing gasoline for automobiles, generating electricity, and selling materials such as gold and silver.
This extraction and the methods used, however, deplete the earth of its natural resources and cause damage and pollution in its wake. Agriculture is foundational for both everyday life, as well as the economy as a whole. It also, however, can have profound effects on the planet. Agricultural pollution occurs when contamination created as a by-product of raising livestock and growing food crops is released into the environment, and the contamination is vast.
Land pollution touches essentially every area of the living world, including:. Given the disastrous effects of land pollution, taking preventive measures to reduce its impact moving forward is crucial. Given that the use of pesticides and chemicals in farming and agriculture greatly contribute to land pollution, finding alternatives will help to reduce the environmental impact. Farmers, for instance, can use natural ingredients by switching from bio-fertilizers to manure.
Another option is to contribute to or volunteer in an urban garden in your neighborhood. Reforestation involves replanting an area with trees.
This can be needed for areas that have experienced wildfires, for instance, or where trees had been chopped down and milled. This process helps to bind the soil, which helps to protect it from land pollution and prevents soil erosion and flooding. At the individual level, there are many things we can do to reduce our contribution to land pollution. With the growing awareness around what can be recycled and an increase in recycling bins in many cities, it has never been easier to recycle.
What is Land Pollution? Urbanization and Construction While urbanization is not in itself littering, large quantities of people living, producing trash and littering in a dense area does inevitably lead to land pollution.
Mining Mining is the extraction of minerals and other geological materials from the ground, which are then used for a wide range of purposes, including but not limited to, producing gasoline for automobiles, generating electricity, and selling materials such as gold and silver. Using Fewer Pesticides and Chemicals in Agriculture Given that the use of pesticides and chemicals in farming and agriculture greatly contribute to land pollution, finding alternatives will help to reduce the environmental impact.

Soil Contamination: Its Causes, Effects, and Solutions
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.
Soil contamination refers to the destruction of land that could be used constructively by human activities, either directly or indirectly. Presently, , ha of UK land is thought to be contaminated by toxic elements such as lead and arsenic. The same goes for the other industrialized nations which are the worst hit. The developing countries are also steadily but surely moving toward this direction. This should be cause for great concern considering the devastating effects soil pollution brings to the environment. Industries are by far the worst polluters of the soil with all the chemicals they release into the environment be it in liquid or solid form.
soil fertility in place of chemicals. Another common measure used to. minimize soil pollution is controlling.

For example, in some parts of China, soil that is polluted with heavy metals is nevertheless used to grow grain. How is climate change affecting the economy and society? We tend to look skywards when talking about pollution, but this problem is not confined to our skies.
We tend to look skywards when talking about pollution, but this problem is not confined to our skies. The soil in which our fruit and vegetables grow is also suffering its consequences, the effects of which getting to us directly, for instance, through the aforementioned foodstuffs. The time has come to look after what lies under our feet!
This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review.

Беккер оглянулся. Убийца целился, высунувшись из окна. Беккер вильнул в сторону, и тут же боковое зеркало превратилось в осколки. Он почувствовал, как этот удар передался на руль, и плотнее прижался к мотоциклу. Боже всевышний. Похоже, мне не уйти.
Работайте, - поторопил Фонтейн. На ВР последняя стена стала уже тоньше яичной скорлупы. Джабба поднял брови. - Хорошо, это ничего не дает. Начнем вычитание.
Его падение пронзило Стратмора холодным ужасом - отчаянный крик и потом тишина.
