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.

Find out its causes and effects, but most importantly the solutions to control and prevent land pollution, and how you can contribute to reduce it. Land pollution is a heavy topic. With its direct impact on the environment and consequently on the health of humans, animals, and plants, soil pollution is a real problem that involves both political powers and citizens. Soil is not a renewable resource. Its degradation can be rapid a few years or decades while it takes several thousands of years to form and regenerate.

Soil Pollution Diseases

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. The concern over soil contamination stems primarily from health risks, from direct contact with the contaminated soil, vapours from the contaminants, or from secondary contamination of water supplies within and underlying the soil. In North America and Western Europe the extent of contaminated land is best known, with many of countries in these areas having a legal framework to identify and deal with this environmental problem.

Soil Contamination, Risk Assessment and Remediation

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.

Solutions for Soil Pollution

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.

Environmental Risk Assessment of Soil Contamination. Environment pollution is a burning topic of the day. Air, water and soil are being polluted alike.

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 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. Responsibilities may include protecting resources associated with land e.


Soil is fundamental to human life on Earth. Most plants require a soil substrate to provide water and nutrients, and whether we farm the plants.


SOIL POLLUTION

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.

 И вы не хотите ничего предпринять. - Нет. Он подстраховался - передал копию ключа анонимной третьей стороне на тот случай… ну, если с ним что-нибудь случится. Это можно было предвидеть, - подумала Сьюзан. -Ангел-хранитель.

Он это сделал. Идиот! - Она замахала бумагой.  - Он обошел Сквозь строй. Посмотри.

Из темноты раздался протяжный вопль, и тут же, словно из-под земли, выросла громадная фигура, эдакий грузовик, несущийся на полной скорости с выключенными фарами. Секундой позже произошло столкновение, и Стратмор, сбитый с ног, кубарем покатился по кафельному полу шифровалки. Это был Хейл, примчавшийся на звук пейджера.
