SOIL POLLUTION
AND
SOIL REMEDIATION
Soil pollution
Metal and Heavy Metal Radionuklides
BTEX (Benzene, Toluene, Ethyl-
benzen, Xylene)
PAH (Polycyclic Aromatic
Hydrocarbon)
PCB (Polychlorinated
Byphenyl)
Human Activities
Xenobiotic Chemicals
Industrial Activities
Agricultural Activities
Pesticides and Fertilizers Waste Disposal
Oil and Fuel Dumping
Natural Sources
Mineral Degradation Weathering
Effects of Soil
PollutionsHealth of Humans
Effect the genetic-make up of the body causing congenital illness , chronic health, sicken livestock and food poisoning
Growth of Plants
Most plant are unable to adapt, lack quality
and nutrients, may contain poisonous
substance
Decreased Soil
fertilityFungi and bacterial that bind it together begin to decline
Changes The Soil
Structure
The death of many soil organism can lead to
alteration in soil structure and force other predators to
move in search of food
Change cin
Climate Patterns
Hazardous pollution can lead the loss of ecosystems

Bioremediation Thermal Treatment
Thermal TreatmentEx-situ & In-situ Treatment
Examples of in-situ thermal treatment (ISTT) by applying steam-air-injection (TUBA method) or thermal wells (THERIS method) to remove source zones like CHC or BTEX.
Bioremediation Intinsic• Using indigenous
microorganism to degrade contaminant
Bioventing • Stimulation in gas
condition adding in soil
Biostimulation• The adding of
nutrient such as N and P
Bioaugmentation• Adding inoculation
Phytoremediation• Using plants to
absorb contaminant
Phyto-extration
• Absorbing contaminant by roots plants and translocation it to the part of plants
Rizo-filtration
• Absorbing contaminant by the root plants and precipitate the metal contaminant from wet land or groundwater
Phytodegradation or Phytotransformation
• Breakdown contaminants taken up by plants through metabolic process whitin the plant
Phytistabilization
• Immobilization of contaminants in soil through absorption & accumulate by roots, adsorbtion onto roots or precipitation within root zone
Phytovolatilization
• Evaporate contaminants which are water soluble by taken up it
