soil pollution an overview
Soil Pollution; An Overview
  • Soil pollution is the contamination of soil by harmful substances.
  • Pollution occurs when contaminants overload the storage and processing of substances in the soil.
  • Soil lacking in nutrients leads to less nutritious foods due to the contamination.
sources of contamination
Sources of Contamination
  • Point-source contamination is the cause of pollution in landfills, radioactive waste dump sites, drainage from mining, and vehicular emissions/spills.
  • Nonpoint-source contamination is caused by chemicals, medication, and microbes.
the extent of contamination
The Extent of Contamination
  • Soil pollution may be shallow, from the surface to a depth of 3 feet.
  • The soil can move through only the top 6 inches of soil.
  • Any deeper contamination is caused through seepage and flow of water.
soil cleanup
Soil Cleanup
  • The process of removing toxic substances is called remediation.
  • Current techniques include excavation of contaminated soil, washing the soil, and changing the properties of contaminants to make them less toxic.
sources of soil pollution
Sources of Soil Pollution
  • Agriculture chemicals such as pesticides, fungicides and herbicides.
  • The contents of landfills being carried by rain into the soil and water.
  • Industry pollution heavy metal and chemical pollutants being released.
  • Feedlots damage soil health

through excess manure.

  • Sewage sludge from

treatment facilities.

effects of soil pollution
Effects of Soil Pollution
  • Water pollution, caused by water running over polluted soil.
  • Air pollution produced by volatile compounds produced by the polluted earth.
  • Plant contamination through the soil where the vegetation is grown. Animals who eat the plants get the chemical in their body, which can lead to health issues if eaten.
  • Reduction of soil health, such as the

slowing of plant growth and acidity.

health effects from soil pollution
Health Effects from Soil Pollution
  • Cancer can be caused by pesticides commonly used on agricultural lands.
  • Neurological problems can be caused in children by lead in the soil.
  • Tissue damage and irritation can be caused by mercury in the soil.
methods of controlling soil pollution
Methods of Controlling Soil Pollution
  • Preventing soil erosion by planting new vegetation in areas prone to erosion.
  • Household chemical disposal through designated waste centers.
  • The proper use of chemical killers or the use of non-toxic killers.
