Soil Contamination, Risk Assessment and Remediation

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.

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.

What on earth is not polluted? How far this is going to bother us and our coming generations? We need to be prepared when the coming generations point their fingers to us for contaminating the earth so badly. Even the soil, the richest form of earth is polluted, how? Let us look in to what is soil pollution, its causes , types , prevention and effects. Soil pollution is the addition of chemicals to the soil in quantities that are toxic to the environment and its residents. This addition is mostly by human activities such as mining, modern practices in agriculture, deforestation, indiscriminate dumping of human generated trash and unregulated disposal of untreated wastes of various industries.

In the case of contaminants which occur naturally in soil, even when their levels are not high enough to pose a risk, soil pollution is still said to occur if the levels of the contaminants in soil exceed the levels that should naturally be present. All soils, whether polluted or unpolluted, contain a variety of compounds contaminants which are naturally present. Such contaminants include metals, inorganic ions and salts e. These compounds are mainly formed through soil microbial activity and decomposition of organisms e. Additionally, various compounds get into the soil from the atmosphere, for instance with precipitation water, as well as by wind activity or other types of soil disturbances, and from surface water bodies and shallow groundwater flowing through the soil. When the amounts of soil contaminants exceed natural levels what is naturally present in various soils , pollution is generated. There are two main causes through which soil pollution is generated : anthropogenic man-made causes and natural causes.


soil fertility in place of chemicals. Another common measure used to. minimize soil pollution is controlling.


Land Pollution: Causes, Effects, and Prevention

With the rise of concrete buildings and roads, one part of the Earth that we rarely see is the soil. It has many different names, such as dirt, mud, and ground. However, it is definitely very important to us. The plants that feed us grow in soil, and keeping it healthy is essential to maintaining a beautiful planet.

Soil Contamination: Its Causes, Effects, and Solutions

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. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge.

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. However, as a first and foremost step, it requires to be understood very Skip to main content Skip to table of contents. This service is more advanced with JavaScript available.

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! Soil pollution is mostly caused by chemical substances produced by human activity. The soil is the skin of the earth, a mantle full of scars, thousand-year-old wrinkles and more recent injuries caused both by man and nature itself. Some of these ulcers are incurable — such as the extinction of species —, whereas others jeopardise health and food security, all of which threaten the well-being of the world's 3. This invisible affliction appears when the concentration of pollutants on the surface becomes so high that it harms land biodiversity and endangers health, particularly through food.


Some the causes of soil pollution can be as follows: • Industrial effluents like harmful gases and chemicals. Use of chemicals in agriculture like pesticides, fertilizers and insecticides. These chemicals also effect beneficial organisms like earthworm in the soil and lead to poor soil quality.


SOIL POLLUTION

Soil contamination or soil pollution as part of land degradation is caused by the presence of xenobiotics human-made chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste. The most common chemicals involved are petroleum hydrocarbons , polynuclear aromatic hydrocarbons such as naphthalene and benzo a pyrene , solvents , pesticides, lead , and other heavy metals. Contamination is correlated with the degree of industrialization and intensity of chemical substance.

Она взглянула на него с холодным презрением. Бринкерхофф поднял руки в знак капитуляции. - Извини. Беру свои слова обратно.

 Должно быть, Танкадо держится в стороне от таких вещей, но всем известно, что он гений. Это культовая фигура, икона в мире хакеров. Если Танкадо говорит, что алгоритм не поддается взлому, значит, так оно и .

Странно, но его очки ничуть не пострадали. Странные очки, подумал Беккер, увидев проводок, который тянулся от ушных дужек к коробочке, пристегнутой к брючному ремню.

Стратмор, глядя в темноту, произнес бесцветным голосом, видимо, уже все поняв: - Да, Сьюзан. Главный банк данных… Сьюзан отстраненно кивнула. Танкадо использовал ТРАНСТЕКСТ, чтобы запустить вирус в главный банк данных.

Все стояли не шелохнувшись. - Да вы просто с ума все сошли, что ли? - закричал Джабба.  - Звоните Танкадо.

ГЛАВА 33 Токуген Нуматака смотрел в окно и ходил по кабинету взад-вперед как зверь в клетке. Человек, с которым он вступил в контакт, Северная Дакота, не звонил. Проклятые американцы. Никакого представления о пунктуальности.

Pollution, Land

Но вместо признаков срыва Фонтейн обнаружил подготовительную работу над беспрецедентной разведывательной операцией, которую только можно было себе представить. Неудивительно, что Стратмор просиживает штаны на работе.
