Soil & GW Remediation
(Civil and Environmental Engineering)
Solution
Qn# 1
EXPLANATION:
A) K ow - 3) octanol-water partitioning coefficient is the ratio of chemical concentration in octanol phase(hydrophobic) to its concentration in aqueous phase(hydrophilic). it is used to understand the hydrophobicity of the compound.
B) K d - 1) it is called as distribution coefficient is the soil-water partitioning coefficient. it is used to calculate the soil concentration that is proactive of ground water. so this is the linear coefficient between aqueous and solid phase.
C) K oc - 5) it is the soil organic carbon-water partitioning coefficient. it is the distribution coefficient restricted to total organic carbon content. used for predicting mobility of organic soil contaminants.
D) K H - 4) it is the air-water partitioning coefficient. so it is used for partitioning of a compound between liquid and gaseous phase.
E) V p - 2) it is used to describe the equilibrium between compound and gaseous phase.
ANSWER is
A) - 3)
B) - 1)
C) - 5)
D) - 4)
E) - 2)
