Bioaccumulation
the increasing concentration of the material in an organism over time.
Phytoremediation
clean up of the environment using plants.
Leachate
liquid that dissolves and carries substances as it passes through soil.
Anaerobic
processes or environments that do not require or contain oxygen.
Biomagnification
the increase in concentration of a chemical or element as it moves up the food chain.
Dilution
mixing of a substance with air or water (which reduces its concentration)
Aerobic
processes or environments that require or contain oxygen.
Permeable
fluids can flow through.
Dispersion
scattering of a substance away from its source.
Factors affecting air transport
Pollutant’s properties
Wind speed
Direction of prevailing winds
Precipitation
Photolysis
breakdown of compounds by sunlight.
Deposition
the laying down of sediment carried by wind, flowing water, the sea or ice
Crude Oil
(petroleum) a mixture of many chemicals. This includes Paraffin Wax, Asphalt & Methane.
WHMIS (Workplace Hazardous Materials Information System)
a system of easy- to- see warning symbols on hazardous materials.
MSDS (Material Safety Data Sheets)
detailed information sheet about a potentially hazardous product.
Waste Collection Sites
where waste is collected in such a manner that does not allow harmful chemicals from entering the environment.
Transport of Consumer goods
when goods are transported to retailers through where the product is first bought
Transport
release of the chemical at the source
dispersion of the chemical in the atmosphere
deposition of the chemical in soil or water
Transport in Groundwater
Movement of underground water between soil grains
Factors Affecting Groundwater Transport
Number of pores in the soil
Connection of the pores
Substances that contaminate groundwater
Transport in Surface Water
The movement of water above ground to different water bodies
Transport in Soil
evaporation
absorption by plants
runoff
soaking into soil dissolving
Dispersion
scattering of a substance away from its source
Deposition
change of state from a gas to a solid
Water table
top of the groundwater zone
Permeable
fluids can flow through
Biodegradation
breakdown of materials by organisms like earthworms, bacteria, and fungi (through hydrolysis)
Factors affecting biodegradation
Temperature (bacteria like it warm)
Soil moisture (should be moist)
pH (preferably between 5-8)
oxygen supply (more O2 for aerobic bacteria)
nutrient availability (cut grass has more nutrients than paper but both decompose)
Impact of oil spills on the environment
they get evaporated or dispersed into water. This can make water unsafe for aquatic organisms to live in & unsafe for any other organisms to ingest.
Impact of oil spills on people
they leak into water sources & kill off the organisms we need for food sources, like fishing & hunting
New oil spill clean-up procedures
new & improved government regulations have been established to deal with future spills
Transport of Consumer goods
when goods are transported to retailers through where the product is first bought
Disposal of Hazardous Chemicals
when chemicals cant normally be disposed of, they must be disposed of in an orderly manner
Waste Collection Sites
where waste is collected in such a manner that doesnt allow harmful chemicals from entering the environment
Hydrocarbons
emissions that contaminate soil by clogging up soil pores
Concentration of pollutants can be changed using
Dispersion
Dilution
Biodegradation
Phytoremediation
Photolysis
