Question 6

silicates (clay), carbonates, lignin, and other biological mater

Answer 6

Components of soil.

Question 7

lignin

Answer 7

the stringy fibres from wood, breaks down into fulvic acid, composes 0.1-7% of the soil

the stringy fibres from wood, breaks down into fulvic acid, composes 0.1-7% of the soil

Answer 8

lignin

Question 9

fulvic acids

Answer 9

chemicals that form due to the breakdown of lignin. Have multiple benzene rings and many acidic active groups.

Question 10

chemicals that form due to the breakdown of lignin. Have multiple benzene rings and many acidic active groups.

Answer 10

Fulvic Acids

Question 11

Important properties for soil contaminaation

Answer 11

lipophilicity, and vapor preasure

Question 12

lipophilicity, and vapor preasure

Answer 12

Important properties for soil contaminaation

Question 13

Volitization

Answer 13

the spontanious escape of chemicals into the air

Question 14

the spontanious escape of chemicals into the air

Answer 14

Volitization

Question 15

wicking

Answer 15

the particles are able to volitize more easiy in wet soil because they are drawn upwards through the water.

Question 16

the particles are able to volitize more easiy because they are drawn upwards through the water.

Answer 16

wicking

Question 17

vapor preasure and volitization rate

Answer 17

the higher the VP the faster it will volitize

Question 18

leaching

Answer 18

when the chemical in the soil gets washed away by water

Question 19

when the chemical in the soil gets washed away by water

Answer 19

leaching

Question 20

Leaching equation

Answer 20

R=1/(Kd(1-p^(2/3))dx) where Kd is the soil/water partition, d is the soil density, and p is the pore water fraction

Question 21

R=1/(Kd(1-p^(2/3))dx) where Kd is the soil/water partition, d is the soil density, and p is the pore water fraction

Answer 21

Leaching equation

Question 22

mobility index for a particle in the soil

Answer 22

MI=log(SV/Kom) Where S is the solubility in mg/L, V is the vapor pressure in mm mercury, and Kom is the soil partition coeficient

Question 23

MI=log(SV/Kom) Where S is the solubility in mg/L, V is the vapor pressure in mm mercury, and Kom is the soil partition coeficient

Answer 23

mobility index for a particle in the soil

Question 24

calculating Kd=

Answer 24

=Kom*Fom where F om is the fraction of organic matter in the soil.

Question 25

=Kom*Fom where Fom is the fraction of oraganic mater in the soil.

Answer 25

calculating Kd=
