Soil Contamination, Risk Assessment and Remediation
Soil pollution has many sources, from agriculture to industry to human activity. Polluted soils affect harm life and, in turn, wildlife. Depending upon the polluting agent, pollutants can persist in the environment. Solutions, therefore, involve not just removing a source of pollution but also cleaning up and restoring the polluted area. Adding to the complexity of soil pollution is nonpoint source pollution NSP , which enters the environment through runoff.
Take any action at your disposal to reduce soil pollution, as you may not always find a clearly defined source. Sulfur dioxide emissions can cause acid rain and forest destruction. Fortunately, the introduction of scrubbers on smokestacks of coal-burning power plants has produced some progress in this arena. The U. Environmental Protection Agency EPA reports a 71 percent decrease in sulfur dioxide concentrations from to Help solve the problem by contacting your legislators and asking them to encourage development of alternative fuel sources.
In the home, conserve energy use; the less you use, the less pollution ends up in the air and soil. Consider the amount of needlessly generated waste. According to the Clean Air Council, almost one-third of the waste in the U. Chemicals used in paper manufacturing can end up in the soil.
Choose wisely when shopping; avoid purchasing products with excessive packaging. Reuse holiday wrap, or cut down on the amount you use. The EPA has identified agricultural runoff as the primary source of water pollution. Runoff contains pesticides, fertilizers, and agricultural waste that can have harmful effects on soils.
Excessive amounts of phosphates, phosphorus and nitrogen found in fertilizers can cause fish and plant kill, resulting in contaminated soils. Use organic herbicides when gardening, or none at all. Plant native plants, which thrive in local conditions, often making pesticide use unnecessary. Help restore polluted wetlands. A single acre of wetlands can hold more than of one and a half million gallons of water, which runoff can taint, eventually leading to soil pollution.
Work to restore wetlands and reduce NSP. Support local conservation efforts by donating to or volunteering with organizations such as The Nature Conservancy that purchase land for restoration. Finally, simply reduce your negative impact on the environment. Despite educational efforts, the average American generates more than four pounds of trash daily, more than seventy percent of which ends up in landfills, where toxins leach into the soil.
Recycle whenever possible to help ease soil pollution. Use cloth bags instead of paper or plastic at the grocery store, and substitute polycarbonate bottles for plastic water bottles.

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. However, like all other forms of nature, soil also suffers from pollution. The pollution of soil is a common thing these days, and it happens due to the presence of man-made elements. According to Environmental Pollution Centers, soil pollution is,.
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.
Soil Pollution Diseases
While exposure to soil pollutants is generally less problematic than exposure to air and water pollution, it might still have serious effects on children who usually play on the soil. Being in closer proximity to potential pollution, children could accidentally swallow soil particles while playing on the ground. Soil pollutants, including chemicals and pathogens, have interchangeable liquid, solid or gaseous forms that mix until an equilibrium is reached between the three. The solid forms are absorbed or mixed with soil particles, liquids fill the voids made of pores between soil particles, and the gaseous forms surround the air between soil particles. This means that we can be exposed to gaseous, liquid and solid forms of soil pollution separately or together at the same time. Soil pollution may enter our bodies directly - through the inhalation of soil dust or soil particles, or through skin contact, or indirectly - through the consumption of food, especially vegetables grown in contaminated soil, or by inhaling the toxic vapors of volatile chemicals polluting the soil.
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.

The land within the boundaries of the United States—covering nearly 2. The use of land, what is applied to or released on it, and its condition change constantly: there are changes in the types and amounts of resources that are extracted, the distribution and nature of land cover types, the amounts and types of chemicals used and wastes managed, and perceptions of the land's value. While human activities on land including food and fiber production, land development, manufacturing, and resource extraction provide multiple economic, social, and environmental benefits to communities, they can also involve the creation, use, or release of chemicals and pollutants that can affect the environment and human health. EPA works with other federal agencies, states, and partners to protect land resources, ecosystems, environmental processes, and uses of land through regulation of chemicals, waste, and pollutants, and through cleanup and restoration of contaminated lands. The complex responsibilities of land management underscore the challenges of collecting data and assessing trends on the state of land. Numerous agencies and individuals have responsibilities for managing and protecting land in the United States.
Господи Иисусе! - воскликнул водитель. - С вами все в порядке. Мы уж думали, вы все погибли. Сьюзан посмотрела на него отсутствующим взглядом. - Чед Бринкерхофф, - представился. - Личный помощник директора. Сьюзан сумела лишь невнятно прошептать: - ТРАНС… Бринкерхофф кивнул.
Отлично. Он обедает там сегодня с одной из наших сопровождающих. - Ролдан понимал, что сейчас они скорее всего лежат в постели, но ему не хотелось оскорблять чувства звонившего. - Оставьте паспорт у администратора, его зовут Мануэль. Скажите, что вы от. Попросите его передать паспорт Росио.
ТРАНСТЕКСТ выступал серым силуэтом в слабом сумеречном свете, проникавшем сквозь купол потолка. Все лампы наверху погасли. Не было видно даже кнопочных электронных панелей на дверях кабинетов.
Тень Гиральды падала на площадь, как срубленная гигантская секвойя. Халохот внимательно проследил взглядом всю ее длину. В дальнем конце три полоски света, прорываясь сквозь прорези, четкими прямоугольниками падали на брусчатку мостовой. Один из прямоугольников вдруг закрыла чья-то тень.
Она вглядывалась в глаза Танкадо - и видела в них раскаяние. Он не хотел, чтобы это зашло так далеко, - говорила она. - Он хотел нас спасти. Но снова и снова он протягивал руку, так, чтобы люди обратили внимание на кольцо.
Это абсолютно исключено. - Спасибо.
Есть ли в Севилье такое место, где тусуются панки. - No lo se, senor. He знаю.
Пуля ударила в закрывающуюся дверь. Пустое пространство зала аэропорта открылось перед Беккером подобно бескрайней пустыне. Ноги несли его с такой быстротой, на какую, казалось ему, он не был способен. Когда он влетел во вращающуюся дверь, прозвучал еще один выстрел.
Он разглядывал роскошную внутреннюю отделку, выстроившиеся в ряд компьютеры, диваны, книжные полки, залитые мягким светом. Увидав королеву шифровалки Сьюзан Флетчер, Чатрукьян моментально отвел .
