Causes And Effects Of Soil Pollution And Its Effects On Plants

Poor soil management can lead to biological, chemical, and physical degradation, which can in turn negatively alter the activity of

Bioremediators need to be able to grow in order to remediate the soil of pollutants. The purpose of this research is to determine whether the presence of Stropharia rugoso-annulata in the soil will support and accelerate the growth of ryegrass in a mutualistic symbiotic relationship. If the growth of the ryegrass is accelerated and supported, the combination of the two bioremediators could potentially accelerate the degradation of PAHs in the soil. Techniques such as soil washing, soil flushing, vitrification, etc., exist to remediate contaminated soil. Although, these techniques are effective, they also disturb the natural environment to some degree. Bioremediation is often accomplished in situ resulting in minimal environmental disturbance. This study is being performed because healthy soil is a limited resource that needs to be preserved and replenished. The state of soil can impact the health of humans, animals, and ecosystems, therefore, it’s important to be able to monitor and control the pollutants in

Other pollution sources include chemical plants, coal-fired power stations, oil refineries, nuclear waste disposal activity, large animal farms, plastic factories, and metal production factories. The soil becomes contaminated by many chemicals and pathogens; this passes on to humans through direct contact via food and water. Overuse of pesticides and chemical fertilizers causes toxins to enter the food chain.

Soil pollution also referred to as soil contamination occurs when degradation or destruction of the earth’s surface and soil occurs directly or indirectly as a result of human activities. As Americans we tend to abuse the use of things such as cars for driving, books, paper, and computers without the knowledge of where it will end up. According to the food and Agriculture Organization approximately 40 percent of food in the U.S. goes to waste. After the garbage man has taken the materials, it ends up in a huge or small landfill waiting to be emerged into the soil. The average person generates

Agricultural runoff is another big factor in water pollution and it is similar to the storm water process but only with more dangerous pollutants. Agricultural waste runoff from the barnyards finds its way into the drainage emerging with the water bodies. The runoff from the barnyard being polluted by the multiple fertilizers used in the crops, pesticides, and livestock waste. Then the polluted water from the runoff makes contact with the water bodies such as lakes and rivers polluting them. There are two essential chemicals for the growth of crops and livestock: nitrogen and phosphorus. However, nitrogen and phosphorous are very dangerous chemicals when they make contact with water or soil. High concentrations of nitrogen and phosphorus in

According to the European Union’s Joint Research Center, soil contains nearly one third of all living organisms, but only about one percent have been identified. Another study in 2003 featured in the journal Ecosystems estimated that 5% of the United State’s soil biodiversity was “in danger of substantial loss, or complete extinction, due to agriculture and urbanization.” (Robbins) The damage comes from multiple sources. Paving or building over soil effectively blocks out the air, water, and light needed to have a functioning soil biome meaning that roads, cities, sidewalks, houses, and businesses have destroyed the soil beneath it. Agricultural practices remove organic material, decreasing food, and then allows fallowed land to become dry and exposed to the elements. Household, industrial, and agricultural toxins can also sterilize soil if not disposed of

Deposition of the various wastes from the excavation process has a significant effect on the composition of micro-organisms on the environment. The remains are composed of biocides and heavy metal which have a significant effect on the environment and its inhabitants. Natural gases that escape such as methane mix with vapor from the environment, resulting in increased acidity of the soil. This reduces the productivity of land as crops do very poorly under such saline conditions (DiGiulion, Wilkin, Miller & Oberley, 2011). The acid levels leak to the earth’s surface changing the oxygen and bacterial contents of the soil structure. This in return results in the plants being unable to fix nitrogen, the consequence being the reduced hydration capability if the plant hampering the formation of cellulose hence weak and contaminated plants will be

Land pollution is one of many pollutions humans fight against. Other pollutions like water pollution, air pollution, soil pollution, thermal pollution, radioactive pollution, and more are crucial as well, but I believe land pollution is one of the major types of pollution because its aftermath. Anyhow, land pollution is the contamination of earth’s surface for the people’s misuse of the land. To be brief, there are different types of land pollution such as solid waste, pesticides and fertilizers, chemicals, and deforestation. According to the United Nations, the U.S is one of the top contributors to land pollution, disposing over 110 million tons of waste per year. Land pollution as well causes the Earth to lose approximately 25 billion tons of valuable topsoil each year. Additionally, it takes at least 500 years for a couple

Current conventional farming practices are also responsible for many pollution problems that would not exist otherwise. The land where we live and grow our food, the water we drink, and the air we breathe are all being contaminated. The large amounts of synthetic pesticides and fertilizers used on our crops are poisoning the soil, air, and water. Toxic heavy metals such

To understand what a contaminated site is, soil contamination should be defined to understand the scope of contamination that can affect a site when observed in a construction context. Soil contamination can be loosely defined as polluted soil, thereby including liquid or solid hazardous substances mixed amongst the earth’s

devastating issue. There many solutions we can think of to solve this problem but this three-way

Industrial pollution has been identified as a major problem in Egypt and is addressed under the National Pollution Prevention Program (NIPPP). (Abou Elela, 2002). Fertilizers industry is considered a sub-sector of the chemical industries which is based on the usage of numerous types of chemicals in large quantities. Increase in fertilizer use has become unavoidable to achieve maximum agricultural harvest. For instance, due to increasing population pressure, the use of chemical fertilizers has become essential in increasing crop production efficiency and meets the high needs for agricultural products in countries with a growing population. Waste from fertilizer factories usually ends up in sediments and soils. This waste may disturb the health of soil ecosystems. Soil quality and productivity in these areas have been dramatically reduced. Heavy metals contamination due to the emission of fertilizer industry is significant problem, which leads to negative influence on soil characteristics and limitation of productive and environmental functions (Kassir et al., 2012). A number of field studies have described the reaction of microarthropods on heavy metal pollution (e.g. Bengtsson and Rundgren, 1988; Hågvar and Abrahamsen, 1990; Rabitsch, 1995; Russell and Alberti, 1998). Soil organisms may play an important role in the transfer of metals through the ecosystem in metal-polluted environments (Janssen et al., 1991). The most numerous groups of microarthropods

Since the time of Darwin (1881), there has been a general perception that the earthworms are beneficial ecosystem engineers that significantly influence soil processes and ecosystem functioning. This has been shown in agricultural systems over the years, where earthworms increase nutrient transformation and plant nutrient uptake (Syers and Springett 1984; Edwards 2000). In addition, earthworms have been put to a use in organic waste management (Edwards 2000). Despite these beneficial effects in agriculture systems and probably in urban settings (Hendrix and Bohlen 2002), some other aspects of earthworm activities, in particularly those are from introduced invasive, are damaging to the natural ecosystems, as invasive earthworms alter plant community structure and diversity, change soil structure and microbial community, and indirectly impact other ground dwelling animals (Hendrix and Bohlen 2002; Bohlen et al. 2004; Hale et al. 2006; Mclean et al. 2006; Holdsworth et al. 2007; Loss et al. 2012).

This study also shows that Zea mays did better in the polluted soil left for six months than in the polluted soil left for three months and than the soil polluted and immediately planted on. This confirms that with time, natural biodegradation occur and the kerosene polluted environment has ability to purify itself, if and only if the source of pollutant is not intermittent.

Land pollution, in other words, means degradation or destruction of earth’s surface and soil, directly or indirectly as a result of human activities. Anthropogenic activities are conducted citing development, and the same affects the land drastically, we witness land pollution; by drastic we are referring to any activity that lessens the quality and/or productivity of the land as an ideal place for agriculture, forestation, construction etc. The degradation of land that could be used constructively in other words is land pollution.
