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.

Soil and Water Pollution Monitoring, Protection and Remediation

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 and water quality management and treatment will be covered. However, the main focus will be 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 will be interested in the detailed design, operation, management, process control for soil and water quality monitoring, and applied modelling issues presented in this issue. For this special issue, we invite authors to contribute original research as well as review articles on recent advances made on techniques and methodologies in the following areas: soil pollution prevention and remediation. This Special Issue will present a comprehensive collection of timely, novel, and innovative research case studies in the area of soil remediation and water treatment.

SOIL POLLUTION

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.

Metrics details. A mounting body of the literature suggests that environmental chemicals found in food and water could affect female reproduction. The potential impact of Bisphenol A BPA , Phthalates and Perfluoroalkyl substances PFAS on female reproduction, in particular on puberty, PCOS pathogenesis, infertility, ovarian function, endometriosis, and recurrent pregnancy loss, in both humans and animals, will be discussed in this report in order to provide greater clinician and public awareness about the potential consequences of these chemicals. Thus proper education about these chemicals can help individuals decide to limit exposure, ultimately alleviating the risk on future generations. The constantly increasing pollution of the environment has been one of the greatest concerns for science and the general public in the last few decades. Water and soil pollutants represent two major categories of environmental pollution [ 1 ]. Water- and soil-polluting substances are often due to man-made wastes such as household garbage, manufacturing and agricultural wastes, fertilizers used by farmers, oil spills, and radioactive materials [ 1 , 2 , 3 ].

Groundwater 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. 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.

Groundwater pollution also called groundwater contamination occurs when pollutants are released to the ground and make their way down into groundwater. This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution. The pollutant often creates a contaminant plume within an aquifer. Movement of water and dispersion within the aquifer spreads the pollutant over a wider area. Its advancing boundary, often called a plume edge, can intersect with groundwater wells or daylight into surface water such as seeps and springs, making the water supplies unsafe for humans and wildlife.

Environmental Risk Assessment of Soil Contamination. Environment pollution is a burning topic of the day. Air, water and soil are being polluted alike. Soil being a "universal sink" bears the greatest burden of environmental pollution. It is getting polluted in a number of ways. There is urgency in controlling the soil pollution in order to preserve the soil fertility and increase the productivity. Pollution may be defined as an undesirable change in the physical, chemical and biological characteristics of air, water and soil which affect human life, lives of other useful living plants and animals, industrial progress, living conditions and cultural assets.

Groundwater is also one of our most important sources of water for irrigation. Unfortunately, groundwater is susceptible to pollutants. Groundwater contamination occurs when man-made products such as gasoline, oil, road salts and chemicals get into the groundwater and cause it to become unsafe and unfit for human use. Materials from the land's surface can move through the soil and end up in the groundwater. For example, pesticides and fertilizers can find their way into groundwater supplies over time. Road salt, toxic substances from mining sites, and used motor oil also may seep into groundwater.

Подумать. - Что вы имеете в виду. - Да он смеялся над нами.

Как я могла не выключить монитор. Сьюзан понимала: как только Хейл заподозрит, что она искала что-то в его компьютере, то сразу же поймет, что подлинное лицо Северной Дакоты раскрыто. И пойдет на все, лишь бы эта информация не вышла из стен Третьего узла. А что, подумала Сьюзан, если броситься мимо него и побежать к двери.

Soil Contamination, Risk Assessment and Remediation

Я побежал позвонить в полицию.

Завтра они скажут мне спасибо, - подумал он, так и не решив, правильно ли поступает. Набрав полные легкие воздуха, Чатрукьян открыл металлический шкафчик старшего сотрудника лаборатории систем безопасности. На полке с компьютерными деталями, спрятанными за накопителем носителей информации, лежала кружка выпускника Стэнфордского университета и тестер. Не коснувшись краев, он вытащил из нее ключ Медеко.

Сьюзан словно отключилась от Хейла и всего окружающего ее хаоса. Энсей Танкадо - это Северная Дакота… Сьюзан попыталась расставить все фрагменты имеющейся у нее информации по своим местам. Если Танкадо - Северная Дакота, выходит, он посылал электронную почту самому себе… а это значит, что никакой Северной Дакоты не существует. Партнер Танкадо - призрак.

Но, увидев прислужника в конце ряда и два людских потока, движущихся по центральному проходу к алтарю, Беккер понял, что происходит. Причастие. Он застонал.

А в довершение всего - Цифровая крепость, величайшая опасность, нависшая над разведывательной службой. И со всем этим ему приходится справляться в одиночку. Стоит ли удивляться, что он находится на грани срыва?.

Он едва дышал. - Хоть что-нибудь, - настаивал Беккер.  - Может, вы знаете имя этой женщины. Клушар некоторое время молчал, потом потер правый висок.

Тоже неподвижная, она стояла у дверей шифровалки. Стратмор посмотрел на ее залитое слезами лицо, и ему показалось, что вся она засветилась в сиянии дневного света. Ангел, подумал .

Особенно таких, как Хейл, - зеленых и наивных. Сьюзан посмотрела на него и подумала о том, как жаль, что этот человек, талантливый и очень ценный для АНБ, не понимает важности дела, которым занимается агентство. - Грег, - сказала она, и голос ее зазвучал мягче, хотя далось ей это нелегко.  - Сегодня я не в духе.

Наконец она поняла, что каждая цифра обозначала букву с соответствующим порядковым номером. Она старательно расшифровывала текст, завороженная тем, как на первый взгляд произвольный набор цифр превращался в красивые стихи. В тот момент она поняла, что нашла свою любовь - шифры и криптография отныне станут делом ее жизни. Почти через двадцать лет, получив степень магистра математики в Университете Джонса Хопкинса и окончив аспирантуру по теории чисел со стипендией Массачусетского технологического института, она представила докторскую диссертацию- Криптографические методы, протоколы и алгоритмы ручного шифрования. По-видимому, ее работу прочел не только научный руководитель, потому что вскоре последовал телефонный звонок, а затем по почте ей доставили авиационный билет от АНБ.

 Сэр, - начал Беккер чуть громче, словно обращаясь к глуховатому человеку, - я хотел бы задать вам несколько вопросов.
