Soil contamination refers to the destruction of land that could be used constructively by human activities, either directly or indirectly. Presently, , ha of UK land is thought to be contaminated by toxic elements such as lead and arsenic.

What Is 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.
Land Pollution: Causes, Effects, and Prevention
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.
Types of soil pollution may be agricultural pollution, Industrial wastes and urban activities. Agricultural processes contribute to soil pollution. Fertilizers increase crop yield and also cause pollution that impacts soil quality. Pesticides also harm plants and animals by contaminating the soil.
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.
Soil Pollution Prevention and Remediation
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.
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.

Applied and Environmental Soil Science
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. In this and the next study session we will look more closely at pollution. In this session you will learn about the different types and sources of pollution and the various human activities that can cause pollution. We will also describe the ways pollution can affect different sectors of the environment: water, air and soil. Study Session 8 describes some of the significant effects of pollution on the environment and on human health.
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.
