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.

What Is Soil Pollution?

In this special issue we have invited authors who are scientists and engineers to contribute original research as well as review articles on recent advances made on techniques and methodologies for the soil pollution prevention and remediation. This journal is in the field of soil science and reflects its multidisciplinary nature including treatments for soil treatment and reclamation. Soil pollution probably represents the most faced problem in environmental pollution. This is because soil is a point of concentration and recovery of toxic compounds, chemicals, salts, radioactive materials, or disease causing agents, which have adverse effects on plant growth and animal health.

Soil pollutants can contaminate water: water infiltration is the movement of water from the soil surface into the soil profile and soil is a valuable resource that support cultures and plant life. Soil pollution is the decrease in the productivity of soil due to the presence of soil pollutants. Moreover soil pollutants have an adverse effect on the physical, chemical, and biological properties of the soil and reduce its productivity.

Main causes of soil pollution are as follows: industrial activity, especially since the amount of mining and manufacturing has increased; agricultural activities, pesticides and fertilizers which are full of chemicals that are not fully degradable in nature and are widely utilized around the world; waste disposal, where there is also a large amount of industrial and municipal waste that is dumped directly into landfills without any treatment; and accidental oil spills, where oil leaks can happen during storage and transport of chemicals.

Main effects of soil pollution are effect on health of humans ; effect on growth of plants ; decreased soil fertility ; and toxic dust. Through expanding our understanding and development of innovative techniques to analyze and treat polluted soils, scientists and engineers can play a crucial role in bringing models and technologies to deal with the environment pollution problem effectively.

The relevant fundamental principles of soil quality management and treatment have been covered. However, the main focus is on assessing sustainable treatment technologies and current case studies related to soil remediation, natural and conventional water treatment, and sustainable drainage systems applied for diffuse pollution treatment. Academics, professionals, and students in the soil, water, and environmental engineering, science, and management areas, as well as the geologist and hydrological engineers, should be interested in the detailed design, operation, management, and process control for soil and water quality monitoring and applied modeling issues presented in this issue.

This special issue presents a comprehensive collection of timely, novel, and innovative research case studies in the area of soil remediation. It demonstrates to practitioners how natural and innovative systems can be integrated into traditional soil remediation, which are predominantly applied for the treatment of diffuse pollution. Also, it assesses the design, operation, and management of soil remediation technologies and water treatment performance of sustainable drainage systems including hydrology and modeling.

Topics of interest include soil remediation, clogging and soil hydraulic conductivity, phytoremediation and soil remediation technologies, storm water management, urban runoff treatment, and soil quality parameters.

Specifically papers included in the special issue are related to role of inorganic and organic fractions in animal manure compost in lead immobilization and microbial activity in soil; cadmium phytoremediation potential of Napier grass cultivated in Kyushu, Japan; phytoremediation of gold mine tailings amended with iron-coated and uncoated rice husk ash by vetiver grass Vetiveria zizanioides L.

Storm water runoff from paved streets, sidewalks, and parking lots, and through lawns and storm drains flows, collects and transports waste, salt, pesticides, fertilizer, oil and grease, and other pollutants [ 1 ]. This water drains directly into rivers and sea, without receiving treatment.

During their flow through soil pores, the pollutants are subjects to a series of interactions such as adsorption, volatilization, and plant uptake. Polluted storm water therefore can harm soil plants, fish, and wildlife, while degrading the quality of soil and water. Phytoremediation is an environmentally friendly and low-cost approach for the decontamination of polluted sites and has been greeted with a high degree of public acceptance [ 2 , 3 ].

Therefore research using phytoremediation technology has been encouraged. In particular, metal hyperaccumulation in different species is investigated with the aim of determining the mechanisms associated with the accumulation and detoxification of heavy metals and using these macrophytes and their rhizomes, roots, stems, and leaves for the decontamination of polluted sites.

What is Soil Pollution?

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.

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.

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.

You were introduced to wastes and pollutants in Study Session 1, where we discussed the interactions between humans and our environment. Pollution was defined as the introduction into the environment of substances liable to cause harm to humans and other living organisms. Many human activities pollute our environment, adversely affecting the water we drink, the air we breathe, and the soil in which we grow food.

Могли сбой произойти внезапно, сам по. Размышляя об этом, Сьюзан вдруг вспомнила фразу, сказанную Стратмором: Я попытался запустить Следопыта самостоятельно, но информация, которую он выдал, оказалась бессмысленной. Сьюзан задумалась над этими словами. Информация, которую он выдал… Она резко подняла голову. Возможно ли .

Скорее. Еще одна спираль. Ему все время казалось, что Беккер совсем рядом, за углом. Одним глазом он следил за тенью, другим - за ступенями под ногами. Вдруг Халохоту показалось, что тень Беккера как бы споткнулась. Она совершила судорожный рывок влево и вроде бы закружилась в воздухе, а затем снова прильнула к центру лестницы. Халохот сделал стремительный прыжок.

Старик внимательно разглядывал подозрительного посетителя. Беккер перешел чуть ли не на шепот: - Я здесь, чтобы узнать, не нужно ли вам чего-нибудь.  - Скажем, принести пару таблеток валиума. Наконец канадец опомнился.

В комнате тут же стало тихо. Старший дешифровщик, нескладный тип по имени Морант, не выпускавший сигареты изо рта, недоверчиво уставился на Беккера. - То есть вы хотите сказать, что эти знаки имеют множественное значение.

 - Обычно травматическая капсула не убивает так. Иногда даже, если жертва внушительной комплекции, она не убивает вовсе. - У него было больное сердце, - сказал Фонтейн. Смит поднял брови.

Soil Pollution Prevention and Remediation

Я попросил оказать мне личную услугу. И он согласился поехать. - Конечно, согласился. Вы же мой шеф. Вы заместитель директора АНБ.

Это было письмо. Дорогие друзья, сегодня я свожу счеты с жизнью, не в силах вынести тяжести своих грехов… Не веря своим глазам, Сьюзан медленно читала предсмертную записку. Все это было так неестественно, так непохоже на Хейла, а список преступлений больше напоминал перечень сданного в прачечную белья.

Направь мне официальный запрос. В понедельник я проверю твою машину. А пока сваливай-ка ты отсюда домой. Сегодня же суббота. Найди себе какого-нибудь парня да развлекись с ним как следует.
