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.
Environmental Risk Assessment of Soil Contamination. Environment pollution is a burning topic of the day. Air, water and soil are being polluted alike.
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.
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.
Soil Contamination, Risk Assessment and Remediation
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. Developing countries tend to be less tightly regulated despite some of them having undergone significant industrialization.
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.
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.
Soil Pollution Diseases
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.
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!
Никогда о таком не слышал. Беккер заглянул в справочник Управления общей бухгалтерской отчетности США, но не нашел в нем ничего похожего. Заинтригованный, он позвонил одному из своих партнеров по теннису, бывшему политологу, перешедшему на службу в Библиотеку конгресса. Слова приятеля его очень удивили. Дело в том, что АНБ не только существовало, но и считалось одной из самых влиятельных правительственных организаций в США и во всем мире.
Коммандер устало опустил глаза, затем поднял их вновь. - Сьюзан, выслушай меня, - сказал он, нежно ей улыбнувшись. - Возможно, ты захочешь меня прервать, но все же выслушай до конца. Я читал электронную почту Танкадо уже в течение двух месяцев.
Он понимал, что мы могли решиться на это только в одном случае - если нашли Северную Дакоту. По спине Сьюзан пробежал холодок. - Конечно, - чуть слышно сказала .
