- Pollution Management
- Definition: contamination of the earth and atmosphere to such an extent that normal environmental processes are adversely affected.
- polluted elements are disagreeable, toxic, harmful, objectionable
- Point source & non-point source
- Point source: discrete sources of contamination that can be represented by single points > sources can be tracked
- Non-point source: disperced sources from which pollutants originate and enter the natural environment (numerous sources)
- Cost of pollution
- Death
- Decreased levels of health
- declining water resources
- reduced soil quality
- poor air quality
- Monitoring methods
- soil pollution
- Soil quality is tested using physical, chemical and biological properties, processes and characteristics = monitors changes in soil quality
- Water quality
- Test performed by portable equipment (detects nitrate, nitrite, free chlorine, chloride, fluoride, hardness, etc)
- River-quality tests = BOD (biochemical oxygen demand), COD (chemical oxygen demand), turbidity, ammonia and dissolved oxygen.
- soil pollution
- Biochemical oxygen demand (BOD)
- The more organisms in an area, the more oxygen used.
- BOD is determined by: number of aerobic organisms at that point AND their rate of respiration
- The more organisms in an area, the more oxygen used.
- Definition: contamination of the earth and atmosphere to such an extent that normal environmental processes are adversely affected.
