TRANSPORTATION OF CONTAMINATION

What is the meaning of transportation contamination?

• Support the ecosystem with biotic reaction

• Describes mechanisms to move contaminants from source to recepto

• Transport bacteria to the stem cell

• Transport sources of organic to land

Following are the three mechanism of transportation of contamination except:

• Diffusion

• Advection

• Photosynthesis

• Dispersion

How the transformation process happen?

• Through chemical process and biochemical process

• Through abiotic and biotic process

• Through solid, air and gas medium

• Through the velocity and porous space

What is diffusion?

• is the process by which a contaminant in water will move to the high velocity

• is the process by which a contaminant in water will move through the porous space

• is the process by which a contaminant in water will move from an area of greater concentration toward an area where it is less concentrated.

• is the process by which a contaminant involve with chemical process and reaction

What is advection?

• Advection is the movement of dissolved solute with abiotic factors

• Advection is the movement of dissolved solute under chemical process

• Advection is the movement of solute to the earth

• Advection is the movement of dissolved solute with flowing groundwater

What is the types under dispersion?

• solid and air dispersion

• chemical and nonchemical dispersion

• fast and slow dispersion

• longitudinal and transverse dispersion

Following are chemical reaction under abiotic except:

• Hydrolysis

• Dehydrohalogenation

• Hetetrophic

• oxidation reduction

What is biotic?

• Living process

• Living dead decay

• Living microorganisms

• Living algae

The most important mechanisms of transport of contaminants through soil is

• Dead Living

• Microorganisms

• Leaching

• Landfill

The organisms present in environment must contain:

• carbon

• water and air

• chemical

• oxygen
