The Effects Of Soil Contamination On The Environment

In the world we are living in today, with a growing population of approximately 7 billion, demands on fossil fuels are now greater than ever. Although innovative research on green energy sources have flourished during the past years, fossil fuels remain the dominant source of energy in the world. Methods of extraction and storage for crude oils can become detrimental to the environment if not properly handled. Starting from marine spills, to leakage of underground storage tanks, these anthropogenic activities intoxicate soil and water bodies impacting both terrestrial and aquatic life. However, through a natural process called bioremediation, microbes are able to degrade toxic pollutants and even result in the complete restoration of contaminated sites. This paper will focus mainly on bioremediation of oil-contaminated soils.
Introduction
Soil contamination occurs when an excessive amount of a substance is present in the soil at higher than normal concentration without necessarily causing any direct harm (Vance, Pierzynski, & Sims, 1994). Soil contamination can lead to soil pollution, which is the evolution of soil contamination, causing some type of direct harm; thus a soil can be contaminated but not polluted (Vance et al., 1994). In most cases, oil contaminated soils have some type of direct or indirect negative consequences on the environment. Crude oils, when found in little to excessive amount, can destroy ecosystems and impact human health. A thorough description of
question is what effect does pesticides have on our environment? There is a causation between the usage of pesticides and the impacts on the environment. Before talking about the impacts that pesticides have on the environment, I will briefly explain what is a pesticide and why do farmers use them. My overall topic for my research paper is about how pesticides are effecting our environment. Pesticides have a huge effect on the aquatic life, human health, birds, water(contamination), and soil fertility.
The most significant issues with the land pollution are deforestation, soil contamination, and the improper disposal of garbage. “Land pollution is the degradation or destruction of earth’s surface and soil, directly or indirectly because of human activities; it refers to any activity that lessens the quality and/or productivity of the land as an ideal place for agriculture, forestation, and construction” (CEF, Land Pollution, para. 2). Some people understand land pollution as damaging the earth’s

A. ANALYSIS OF ENVIRONMENTAL IMPACT ON REMEDIATION AND REUSE OF CONTAMINATED LAND.
A contaminated land is a land which contains substances that are actually or potentially hazardous to health or the environment. Land can also be defined as contaminated if only there is significant pollutant linkage. This means that, there must be:
* an evidence of the presence of a contaminant, a pathway and a receptor that might suffer ‘’significant harm’’,
*
will have an effect on existing structures, as they are sensitive. Therefore damage to the structures can occur if proper measures and ground investigations are not carried out. If the soil is compressible it can cause subsidence to adjacent surface structures. Physical conditions of existing structures should be obtained and laboratory tests taken to provide information, which is clear about the behaviour of the surrounding structures.

harmful things. Pollution is the introduction of harmful or poisonous effects of a substance into the environment. It disrupts the balance of people’s lifestyle when they are contaminate. Pollution balance in the environment and ecosystem. The environment is in the process of becoming unsafe or unsuitable to use. Pollution can come in many different form, such as air, water, soil can have pollutant that can wreak havoc on the environment. Pollution can be a form of anything and cause so much harm. It can
question is what effects does pesticides have on our environment? There is a correlation between the usage of pesticides and it's impacts on environment. Before talking about the impacts that pesticides have on the environment, I will briefly explain what is are pesticides and why do farmers use them. My overall topic is about how pesticides are effecting our environment. I have divided the impacts of pesticides in five main topics: aquatic life, health, birds, water(contamination), and soil fertility
Are Conservative and Zero Tillage Systems Beneficial To Enhancing Soil Properties?
Introduction
There are two types of tillage systems that farmers use today, conventional and conservative or zero tillage. Conservative tillage or zero tillage systems are operations where the fields that are seeded have minimal soil disturbance. Conventional tillage systems are operations where the soil has been plowed or cultivated and the soil has been overturned. Conservative tillage includes the uses of
of the detonation of the atomic bomb is the radiation contaminations that are left over. These contaminations spread into water, air, animals, soil and into the atmosphere. What’s worse is that these contaminations have materials that have very long half-life meaning that their radiation effects do not decay quickly. “Many of the substances
living organism is dependent on its immediate environment. Biotic and abiotic components within an environment play an influencing role within the environment, thus organisms can either influence or be influenced by its environment. Environments that are considered to be of a good health are beneficial for a sustainable ecosystem. Environmental health directly affects ecosystems functioning and human health. Unfortunately the health of many environments within South Africa has deteriorated as a result
Pollution is harmful substances in the air that affect the environment and poisonous gases are released in the atmosphere. There several types of pollution, which includes: water, land, and air pollution. All three are very harmful to Earth, and has a dangerous effect in the end, which is included, but not limited to global warming. Pollution that is in the air can eventually lead to health problems among humans, and can even affect the environment for Mother Nature itself, and also animals. Respiratory
