Fate of chemicals in the environment

Fate of contaminant depends on:

• its chemical characteristics

• nature of medium

• environmental conditions

• all answers are right

Partition coefficients tells you about how a substance distributes between two phases

• True

• False

Environmental partition coefficients water and lipid is

• Henry's Law Constant

• Octanol-water partition

• Sorption coefficient

• Bioconcentration factor

Henry's law constant shows environmental partition coefficients of

• water and air

• water and lipid

• water and solid

• water and biota

Henry's Law Constant describes

• a substance dissolving in water (concentration at saturation)

• the tendency of a chemical to volatilise from water into the atmosphere

• the tendency of a chemical to dissolve from water into the soil

• the tendency of a chemical to dissolve from soil into the water

Henry's law states

• $P=K_H\times C$

• $P=\frac{K_H}{C}$

• $P=\frac{1}{K_H\times C}$

• $P=\frac{K_H\times C}{R\times T}$

When log H > 1 substances are called

• volatile

• aerophilic

• aviator

• fliers

When log H < - 2

• hydrophillic

• swimmers

• soluble

• aquaman

When -2< log H < 1 substances are called

• Soliphilic

• Aerobic

• Solid

• Hoppers

Kow is measured in the laboratory and it is a constant

• True

• False
