Relationship between plant animal and soil pollution - Soil pollution

relationship between plant animal and soil pollution

Soil is the link between the air, water, rocks, and organisms, and is These plants then provide valuable habitat and food sources for animals, bacteria, and other If rainfall contains harmful pollutants, the soil acts as a filter; contaminants are. Air is a third critical resource for humans, plants, animals and all other Pollution added to an atmosphere, water, or soil will directly or indirectly affect a natural. Oct 29, Here we link soil to plant transfer (SPT) models for potentially toxic model is used to assess the impact of soil contamination on animal health.

In dry regions, dust can also alert of an approaching enemy. In very dry regions, every time a weapon is fired, it sends out a cloud of dust, and it is difficult to see if the target is hit.

Soil Pollution -- What are the causes of soil pollution-- soil pollution effects

In military operations in the desert, take off formations are messed up by high concentrations of dust. Temperature Regulation Soil temperature plays an important role in many processes, which take place in the soil such as chemical reactions and biological interactions.

This includes important processes like seed germination, bugs and microbes that live in the environment, and how quickly plant and animals break down. In colder soils, there is less biological and chemical reactions compared to warmer ones, therefore, there may be more carbon stored in the soils. Carbon and Nutrient Cycling Soil contains large amounts of stored carbon, nearly 5 times more than the plants that grow in it.

Natural processes are all cyclical. On a global level, the total carbon cycle is more complex, and involves carbon stored in fossil fuels, soils, oceans, and rocks. Physical, biological, and chemical processes in the soil affect the balance in organic carbon compounds, and if they are released to the atmosphere as CO2, or stored in the soil.


This same process occurs with NitrogenPhosphorus, and all other materials. Water Filtration Without soil and soil particles, water would be running on bare rocks! When it rains, the soil acts as a sponge, soaking water into the ground.

From there a few things can happen to the water. The water can be taken up by plants, microbes, and other living things, or the water moves into the underground aquifers and lakes, and flows into streams before eventually making it to the ocean. Man-made soil pollution is usually caused by the improper disposal of waste coming from industrial or urban sources, industrial activities, and agricultural pesticides.

The main pollutants of the soil are the biological agents and some of the human activities. Soil contaminants are all products of soil pollutants that contaminate the soil. Human activities that pollute the soil range from agricultural practices that infest the crops with pesticide chemicals to urban or industrial wastes or radioactive emissions that contaminate the soil with various toxic substances.

Biological Agents Biological agents work inside the soil to introduce manures and digested sludge coming from the human, bird and animal excreta into the soil.

Agricultural Practices The soil of the crops is polluted to a large extent with pesticides, fertilizers, herbicides, slurry, debris, and manure. However, there is little new land that can be brought into production and existing land is being lost and degraded. The United Nations Food and Agricultural Organization states that annually, 75 billion tons of soil, the equivalent of nearly 10 million hectares, which is about 25 million acres, of arable land is lost to erosion, water-logging and salination and another 20 million hectares is abandoned because its soil quality has been degraded.

Contact with contaminated soil may be direct, from using parks, schools etc. Causes of Soil Pollution The redundant, ever-increasing use of chemicals such as pesticides, herbicides, insecticides and fertilizers is one of the main factors causing soil pollution by increasing its salinity making it imperfect for crop bearing and adversely affecting the microorganisms present in the soilcausing the soil to lose its fertility and resulting in the loss of minerals present in the soil, thus causing soil pollution and killing off more than just the intended pest.

Other types of soil contamination typically arise from radioactive fallout, the rupture of underground storage tanks, percolation of contaminated surface water to subsurface strata, leaching of wastes from landfills or direct discharge of industrial wastes to the soil, unfavorable and harmful irrigation practices, improper septic system and management and maintenance, leakages from sanitary sewage, acid rain falling onto the soil, fuel leakages from automobiles, that get washed away due to rain and seep into the nearby soil and unhealthy waste management techniques, which are characterized by release of sewage into the large dumping grounds and nearby streams or rivers.

The harmful effects of soil pollution may come from direct contact with polluted soil or from contact with other resources, such as water or food which has been grown on or come in direct contact with the polluted soil.

Soil Pollution - Everything Connects

Humans Many common soil pollutants are carcinogenic causing humans who are exposed to these pollutants to be far more likely to develop cancer than those who are not. For example, regular exposure to benzene is known to cause leukemia in both children and adults and exposure to polychlorinated biphenyls PCBs is linked to liver cancer.

Soil pollution can also cause neuromuscular blockage as well as depression of the central nervous system, headaches, nausea, fatigue, eye irritation and skin rash.

Soil does not need to be highly contaminated to be harmful to humans. Soil that is not significantly polluted may still harm humans directly though bioaccumulationwhich according to Pollution Issuesoccurs when plants are grown in lightly polluted soil, which continuously absorb molecules of the pollutants.

Since the plants cannot get rid of these molecules, they accumulate in the plant, causing higher amounts of pollution to exist in the plant than in the soil.
